==Robot Combat Kits==
Many people don't have the fabrication or design experience to make a robot on their own, so starting out with a pre-designed kit is a great way to get into the sport. Check out your local events to see what weight-classes are supported. Make sure you know what is included in your kit; radios, batteries, or battery chargers are often optional items.

[[File:Viper_Kit.png|thumb|FingerTech Viper Antweight with Flipper option]]
==150g Kits==
The '''[https://shop.bristolbotbuilders.com/product/antkit/ Bristol Bot Builders]''' kit has the parts you'll need to get started but you'll need to make your own chassis. 
'''[https://nutsandbots.co.uk/product-category/robots/ Nuts and Bots 150g kits]''' come in three flavors, a wedge, a flipper and a grabber. These kits are underweight giving you room to add armor or to customize them. 
'''[https://turnabot.com/ Turnabot]''' has several 3D printed non-destructive robots with lifters and grabbers. The kits come as parts that you can put together yourself, or fully assembled at extra cost. '''[https://turnabot.com/?product=slipper Slipper]''', a Lifter. '''[https://turnabot.com/?product=squeezy Squeezy]''', a Horizontal Grabber.

[[File:SSP Promo Pic.jpg|thumb|SSP Beetleweight Lifter Kit as seen at NHRL]]
The [https://justcuzrobotics.com/shop/p/ssp-robot-kit SSP Lifter Kit] is a fantastic option for beginners as it has a lifter rather than a dangerous spinner, and at just 2.25 pounds for a base kit, it's easy to upgrade.

The '''[https://www.botkits.com/collections/combat-robot-kits/products/mw1-combat-robot-chassis-kit MW1]''' kit is basically half a D2 kit, having only drive wheels and a billet aluminum frame, and is intended for advanced builders who want to add their own weapons and who have the facilities to mill the frame to their requirements. 
The '''[https://kitbots.com/shop/ols/products/weta-x-beetleweight Weta]''' drum bot kit is a classic design with protected wheels for more advanced builders who are ready for an active weapon. 
The '''[https://www.endbots.com/products/vector-beetleweight-kit Vector]'''Link dead 2023-03 kit has a powerful horizontal spinner. This kit and website have been discontinued.

The '''[https://www.fingertechrobotics.com/proddetail.php?prod=ft-3lb-beater-bot FingerTech Beater Bundle]''' offers a menu of materials to make a beater bar bot, but leaves it to the builder to cut and shape the materials to make the frame. 
'''[https://repeat-robotics.com/buy/pbk/ Peter Bar Kit]''' is a highly destructive and successful vertical spinner design, recommended for experienced builders. 
The pricey '''[https://shop.kiwi.engineering/products/beetleweight-drum-robot-kit-exile Exile]''' kit has a tool steel drum spinner and one-piece billet aluminum frame. 

==Bigger Robot Kits==
'''[http://www.battlekits.com/ BattleKits]''' aren't fully functional kits but are drive platforms for larger robots ranging from sixty pound lightweights to two hundred fifty pound Battlebots. You'll need to fashion your own wedge or weapon to make these bots ready for combat.

[[File:RC_Transmitter.jpg|thumb|Dual-stick transmitter]]
Combat robots usually use R/C hobby radio equipment.[http://runamok.tech/RunAmok/radio_func.html] This includes:
*A '''transmitter (Tx)''', the part that the driver/operator of the bot holds. It sends your instructions to the robot.
*A '''receiver (Rx)''' module in the robot to receive your instructions and operate the devices on the bot.
**The receiver module has multiple outputs to connect to those devices. The standard device is a servomotor (servo) for moving things. You can also use adapters, such as [[ESCs]], to make outputs for turning things (like wheels).
**There are combination Rx and ESC available for building small bots and other RC devices.

Many transmitters only work with a few models of receiver. The receiver must be bound (paired) with the transmitter for them to communicate. Most transmitters sold today can be set up to bind to multiple devices, so a single one can operate multiple robots, one at a time.

 
'''Follow directions to safely switch on or off your radio equipment without accidentally activating your robot’s devices.'''
 

=Choosing a Radio=
[[File:FlySkyNoble.jpg|thumb|Pistol transmitter]]
When choosing a radio there are many things to consider but there are three fundamental things that will drive your choice.
*'''Safety:''' Runaway robots can be dangerous, so it is critical that your radio system properly handles what is known as a '''Failsafe''' situation. When the robot loses signal from the transmitter, the receiver must stop all movement and turn off weapons. (Many events require that the radio be turned off while people are in the arena to insure that the robot isn't moved accidentally by a person.) Not all radios have a failsafe feature, and many must be set up or programmed for the correct behavior. For instance, aircraft receivers may continue flying or attempt to land if the transmitter signal is lost.
*'''Form factor:''' You may have a preference on the form factor of your radio transmitter. The pistol-grip types have a throttle trigger and steering wheel, and may be easier to learn, though some people feel they lack fine control. Dual-stick radios are generally the most flexible and often have switches which can be programmed for special operations. Transmitters in the shape of game controllers are increasingly common; you may find this type to be more familiar to operate, and the controls may require very short movements. With time and enough practice, the differences between types may become insignificant. See also: '''[http://runamok.tech/RunAmok/pistol.html Using Pistol Grip Transmitters with Robot Speed Controllers]'''
*'''Functionality:''' Each robot's requirements are different. A simple wedge robot may only need two channels with a third channel enabling a weapon, but some robot designs need even more channels or other radio programming features. If your ESC doesn't have built-in mixing you'll need to find a radio that can do tank-steering [[Radios/Mixing|Mixing]]. See also: '''[http://runamok.tech/RunAmok/radio_func.html Combat Robot Radio Systems - what functions do you actually need?]'''

If you are looking to purchase a radio, take a look at the '''[[Radio List|list of radios]]''' that are known to be suitable for robot combat.

=Common problems=
Since the radio receiver passes signals to the robot's '''[[ESCs|Electronic Speed Controllers]]''' to drive the robot's functions, it can sometimes be difficult to determine if the problem is with the radio or the ESC. To make troubleshooting easier, solutions to common problems that affect the whole system are described here.

Team Run Amok's '''[http://runamok.tech/AskAaron/radio_guides.html Ask Aaron]''' site is a good resource for additional information and troubleshooting.

''This section needs additional details.''

*'''Failsafe:''' What does your receiver do when it loses its signal? Some inexpensive radio systems will act unpredictably with signal loss, while other systems will continue on with their last good signal until they can reconnect. This 'continue' behavior can be useful for some RC systems but can be dangerous for robot combat. Check out the '''[[Radio List|radio list]]''' for systems that can be set up to failsafe appropriately. If your radio system can't failsafe then most events will not allow it, especially for bots that have active weapons. It's important to remember that often the radio defaults will not work correctly and you will need to adjust them.
*'''Signal Loss:'''
*'''Not Binding / Connecting:'''
*'''Compatibility:'''
*'''Too Responsive:'''
*'''Controls Reversed:''' The 'channel mixing' that allows a single transmitter stick to control forward/reverse motion as well as left/right rotation involves the coordination of multiple robot components. Errors in mixing set-up are common and may result in the robot failing to respond to stick inputs in the expected manner. These set-up errors can be difficult to identify and correct. The '''[http://runamok.tech/RunAmok/mixfix4.html Team Run Amok Mixer Fixer]''' will sort out your response symptoms and provide specific instructions to restore correct stick response.
*'''Only one motor responds:'''
*'''Robot hums or whines:'''
*'''Robot won't stop moving:'''

=Radio features and their uses=
If you decide to study all the features of a radio control system, you'll run into language peculiar to those hobbies. Here is a guide to some of the abilities and specs your transmitter and receiver may have, and how they might be useful in robot combat.

*'''Number of channels''' refers to the number of devices that can be operated remotely. Most modern radios have 6 or more, which is fine. A 3 channel truck transmitter might be adequate for a pusher bot only.
*'''Channel mixing''' can break out the motion of 1 stick into 2 motors, allowing 1-stick steering. See [[Radios/Mixing]].
*'''Model memory''' stores a list of robots; they can all have different settings, and you can control any of them with one transmitter.
*'''Reversing''' means the transmitter can command motion in the opposite direction. Some transmitters can be programmed to reverse direction of motion with a switch; if your bot still moves while upside-down, flicking this switch lets you operate the bot with the same stick motions instead of with backwards motions.
*'''Trim''' adjusts the center point of controls. In particular, when a joystick is released and springs back to the center position, proper trim means that the Tx will send a neutral signal.
*'''Sub trim''' adjusts the center point of receiver outputs. You might need that to make sure ESCs shut off when the Tx sends a neutral signal, or to set a default weapon position.
*'''Dual rate (rate limit)''' lets you switch on or off a lower-speed, more sensitive motion mode. This could be used to set a speed limit on a "hot" high-speed bot, but still allow a skilled driver to push it to the limit.
*'''End point adjust''' sometimes called 'ATV' or 'Travel Adjust' - sets travel maximums for a servo or limits an ESC speed output. Examples: can set the perfect level for the tip of the lifter to glide across the arena floor, or reduce a motor speed a bit to match the motor on the other side.
*'''Exponential rate (expo)''' changes the response curve of your joysticks. Changing from linear to exponential response could help you move or steer with precision using short joystick actions, with rapidly increasing speed the farther you push the joystick.
*'''Telemetry''' lets the transmitter receive data from the receiver, and display it or give an audio signal. The most advanced combat robots report things like battery status, overheating parts, electronic overload, and other useful info from the bot to help the team shape their strategy during a fight.
*'''Trainer''' features let you link two transmitters together. This was originally designed to allow for a pilot and his instructor to share the task of flying aircraft. In combat robotics, the trainer feature could be used to let two people control a bot with different roles (e.g., driver & weapon) using two transmitters. (While some bot teams use trainer features, others have two or more separate, non-linked sets of transmitters and receivers for the same purpose.)

Satchmo: /* Choosing a Radio */ added link to explanation of radio features

[[File:RC_Transmitter.jpg|thumb|Dual-stick transmitter]]
Combat robots usually use R/C hobby radio equipment.[http://runamok.tech/RunAmok/radio_func.html] This includes:
*A '''transmitter (Tx)''', the part that the driver/operator of the bot holds. It sends your instructions to the robot.
*A '''receiver (Rx)''' module in the robot to receive your instructions and operate the devices on the bot.
**The receiver module has multiple outputs to connect to those devices. The standard device is a servomotor (servo) for moving things. You can also use adapters, such as [[ESCs]], to make outputs for turning things (like wheels).
**There are combination Rx and ESC available for building small bots and other RC devices.

Many transmitters only work with a few models of receiver. The receiver must be bound (paired) with the transmitter for them to communicate. Most transmitters sold today can be set up to bind to multiple devices, so a single one can operate multiple robots, one at a time.

 
'''Follow directions to safely switch on or off your radio equipment without accidentally activating your robot’s devices.'''
 

=Choosing a Radio=
[[File:FlySkyNoble.jpg|thumb|Pistol transmitter]]
When choosing a radio there are many things to consider but there are three fundamental things that will drive your choice.
*'''Safety:''' Runaway robots can be dangerous, so it is critical that your radio system properly handles what is known as a '''Failsafe''' situation. When the robot loses signal from the transmitter, the receiver must stop all movement and turn off weapons. (Many events require that the radio be turned off while people are in the arena to insure that the robot isn't moved accidentally by a person.) Not all radios have a failsafe feature, and many must be set up or programmed for the correct behavior. For instance, aircraft receivers may continue flying or attempt to land if the transmitter signal is lost.
*'''Form factor:''' You may have a preference on the form factor of your radio transmitter. The pistol-grip types have a throttle trigger and steering wheel, and may be easier to learn, though some people feel they lack fine control. Dual-stick radios are generally the most flexible and often have switches which can be programmed for special operations. Transmitters in the shape of game controllers are increasingly common; you may find this type to be more familiar to operate, and the controls may require very short movements. With time and enough practice, the differences between types may become insignificant.
*'''Functionality:''' Each robot's requirements are different. A simple wedge robot may only need two channels with a third channel enabling a weapon, but some robot designs need even more channels or other radio programming features. If your ESC doesn't have built-in mixing you'll need to find a radio that can do tank-steering [[Radios/Mixing|Mixing]]. See also: '''[http://runamok.tech/RunAmok/radio_func.html Combat Robot Radio Systems - what functions do you actually need?]'''

=Common problems=
Since the radio receiver passes signals to the robot's [[ESCs|Electronic Speed Controllers]] to drive the robot's functions, it can sometimes be difficult to determine if the problem is with the radio or the ESC.

Some inexpensive radio systems will act unpredictably with signal loss, while other systems will continue on with their last good signal until they can reconnect. This 'continue' behavior can be useful for some RC systems but can be dangerous for robot combat. Check out the [[Radio List|radio list]] for systems that can be set up to failsafe appropriately.

Satchmo: /* Programming */ Clarified the mixing set-up process for an Elevon mix

'''Channel mixing''' can direct the motion of 1 control stick on the transmitter into 2 motors, allowing driving and steering with a single control. Without this ability, you would have to control the wheels on the left and right side of the bot with two separate controls (called "tank steering"). Some drivers prefer tank steering, but on many radios it's much harder to activate a robot weapon when both hands are needed for driving.

Channel mixing can be done in the robot with a Dual ESC board that has that feature. When you want to drive a bot with independent [[ESCs]] using a single control, you will either need an inexpensive channel mixing device in the bot, or will need to program mixing in the transmitter.

=Programming=

Most twin-stick transmitters have a menu option for 'Elevon' or 'Delta Wing' mixing. Turning on this option and plugging your left drive motor ESC into receiver channel CH1 (Aileron) and upir right motor ESC into CH2 (Elevator) give you basic forward/reverse throttle and left/right rotation control on your right-stick if using the US standard stick assignments.

'''Important:''' Some transmitters may have no mixing at all. If they have at least TWO programmable mixes it is possible to program your own mix:

ESCs

2021-06-05T01:41:33Z

Satchmo: /* Selecting an ESC */ Clarified 'Channel Mixing' as impacting only dual-channel ESCs

'''Electronic Speed Controllers''', or '''ESCs''', are circuits that let you control motor speed and direction remotely, using a signal from the radio receiver. One circuit board may have one or more motor controllers, and some small ESCs are integrated with a receiver to minimize size and weight for small bots.

[[File:Scorpion_Mini.jpg|thumb|Scorpion Mini ESC by RobotPower]]

=How ESCs work=
An ESC plugs into the receiver. It changes the pulses that would have moved a servo, and makes them into a variable motor voltage instead. ESCs have a connection to draw power from the battery, and another to attach to the motor(s).

There are two completely different types.
*'''Brushed ESCs''' only drive brushed DC motors.
*'''Brushless ESCs''' only drive brushless motors.
*'''Hybrid controllers''' there are some ESCs like some from [https://home.castlecreations.com/ Castle Creations] that can be set to either brushed or brushless mode.

=Selecting an ESC=
'''Note''': Beginners may be quickly overwhelmed at the selection of ESCs available. It is convenient to choose ESCs that are specifically sold for use in combat robotics. A wide range of other ESCs are available for model hobby purposes, but you must select carefully. When in doubt, ask other builders.

Considerations in selecting a suitable ESC include:
*'''Battery Voltage''' - ESCs are rated for a maximum voltage. Exceeding this voltage may lead to immediate failure of the ESC.
*'''Continuous Current''' - An ESC should be able to provide the anticipated current requirement of the motor it controls for the full length of a match. An ESC that cannot provide the required current for the required time will stop working or burn out from thermal overload.

It may be possible to reflash the firmware on an ESC meant for other uses to make it reversible. Here are some examples of ESCs that could be repurposed for robot combat.
*ESCs for '''car and truck''' applications have reversing ability, unless they have the very simplest of radio controls.
*ESCs designed for '''airplane''' flight are often intended to spin a propeller one way only. To save weight, airplane ESCs may also have smaller, lighter heat sinks intended for air cooled operation.
*ESCs made for '''quadcopter/drone''' applications are normally brushless and non-reversible, but can often be modified by reflashing.

Satchmo: /* Selecting an ESC */ General re-write to better define ESC ratings and features

'''Electronic Speed Controllers''', or '''ESCs''', are circuits that let you control motor speed and direction remotely, using a signal from the radio receiver. One circuit board may have one or more motor controllers, and some small ESCs are integrated with a receiver to minimize size and weight for small bots.

[[File:Scorpion_Mini.jpg|thumb|Scorpion Mini ESC by RobotPower]]

=How ESCs work=
An ESC plugs into the receiver. It changes the pulses that would have moved a servo, and makes them into a variable motor voltage instead. ESCs have a connection to draw power from the battery, and another to attach to the motor(s).

There are two completely different types.
*'''Brushed ESCs''' only drive brushed DC motors.
*'''Brushless ESCs''' only drive brushless motors.
*'''Hybrid controllers''' there are some ESCs like some from [https://home.castlecreations.com/ Castle Creations] that can be set to either brushed or brushless mode.

=Selecting an ESC=
'''Note''': Beginners may be quickly overwhelmed at the selection of ESCs available. It is convenient to choose ESCs that are specifically sold for use in combat robotics. A wide range of other ESCs are available for model hobby purposes, but you must select carefully. When in doubt, ask other builders.

Considerations in selecting a suitable ESC include:
*'''Battery Voltage''' - ESCs are rated for a maximum voltage. Exceeding this voltage may lead to immediate failure of the ESC.
*'''Continuous Current''' - An ESC should be able to provide the anticipated current requirement of the motor it controls for the full length of a match. An ESC that cannot provide the required current for the required time will stop working or burn out from thermal overload. Note that inexpensive 'hobby' ESCs often advertise current ratings that are unrealistically high.
*'''Peak Current''' - If brought to a stop by excessive load (stalled) an electric motor can consume a great deal of electrical current. Motors should be geared to avoid stalling, but combat damage can increase loading. Estimate the peak current your motor may require and select an ESC that will not be damaged by that current level.

**Reversible: If you are using the ESC to operate any motor that has to spin both ways (drive wheels, for example), the ESC must be "reversible" — that is, capable of bidirectional operation.
**Battery monitoring and protection, which shuts off the motor to save the battery from destruction due to overuse. Consider if you want your ESC to cut off power to your motor and leave you vulnerable late in a match -- it may be worth risking battery damage to keep fighting!

ESCs may be judged by:
*'''Voltage''' of the battery (and by extension, the motors). Never operate an ESC on a voltage greater than its highest rating.
*'''Current''', which along with voltage determines how much power can be delivered to the motors. An ESCs should be rated higher than the stall current of the motor(s) connected to it; several times higher, if possible.
*'''Cooling''', since combat robotics is extremely demanding on its circuits even though most matches are only a few minutes long. An underrated or low-quality ESC will stop working or burn out if it is driven beyond its capacity to stay cool.
*'''Size''' as all things in robot combat, the physical size of the ESC is a consideration when choosing one for a specific bot. This is especially true in small insect-class robots where every gram counts.

Battery eliminator circuit (BEC)

2021-06-04T21:56:46Z

Satchmo: Added info on linear vs. switching regulators and warning on power consumption by telemetry receivers.

A '''battery eliminator circuit''' (BEC) accepts battery voltage and provides a lower voltage for other circuits, such as the receiver (Rx) or the [[Servos]]. It is so named because it eliminates the need to have a second battery (often called the "receiver battery") of a different voltage.

=How it works=
For several decades, most digital electronic circuits were made to operate using a steady 5 volt (5V) supply of power. There are very few batteries, or combinations of cells, that equal exactly 5V, so in radio-control systems you may see fairly forgiving radio receivers (Rx) and servos that are supposed to be operated with 5 volts, but which work just fine on as little as 4V or as much as 6.5V.

Unfortunately these circuits can be damaged by higher voltages, and the LiPo batteries used in combat robotics are usually a minimum of 7.4V, with larger battery packs much higher. A BEC is a small voltage regulator circuit connected to the full voltage of the battery, which delivers a steady voltage so that the digital electronics operate correctly.

Two types of circuits are used to regulate voltage for a BEC:
* '''Linear Regulators''' are simple and inexpensive, but are inefficient as they simply convert excess current into waste heat. Their capacity to provide current decreases with increasing source voltage. Linear regulators are the common type built into Electronic Speed Controllers (ESCs).
* '''Switching Regulators''' are more complex circuits that very rapidly turn the souce voltage on and off to maintain a stable level, avoiding current waste. Switching regulators are the common type found in standalone BECs.

=BECs built into ESCs=
Many [[ESCs|electronic speed controllers]], such as the RobotPower Wasp and the FingerTech TinyESC, include a BEC circuit that feeds 5 volts back to the receiver. The amount of current provided is sufficient to operate a standard R/C receiver, but may be insufficient to operate a receiver with telemetry - particularly when used with a high souce voltage. Built-in BECs generally do not provide enough power to operate servos connected to the Rx.

=Standalone BECs=
There are several small and light BECs on the market that will provide 5 volts with enough current to run multiple servos and receivers. If you use one of these, be sure to disable the BEC in your ESCs (if any) by using the disable feature or by disconnecting the 5 volt wire from the ESC to the Rx.

=Troubleshooting the BEC=
*If your Rx is not powered at all (no lights, for instance), make sure there is at least one BEC connected and providing power.
*Avoid connecting multiple BECs to the same Rx, unless they are designed to operate that way. Disconnect all but one 5V supply wire to the Rx. Don't disconnect Ground wires; they are still needed. Also, don't disconnect the 5V wires that provide power from the Rx to servo(s).
*If the Rx lights are on, but its behavior is erratic, use a voltmeter to measure the voltage across 5V and Ground terminals on the Rx. (Many Rx will also report their voltage back to the transmitter, which can display it on a screen.)
*If the Rx is working correctly, but the servo(s) are not, the voltage may be just low enough (below 4.8V) that most servos will not operate. Consider adding a standalone BEC, or using a servo that can run on a higher voltage, and therefore get its power directly from the battery.

Choosing a Radio 
When choosing a radio there are many things to consider but there are three fundamental things that will drive your choice.
*Safety: Run away robots can be dangerous, so it is important that your radio system properly handles what is known as a Failsafe. A proper failsafe causes all of the robot systems to stop when it's signal cuts out. Many event procedures require that the radio be turned off while people are in the arena to insure that the robot doesn't move. Not all radios have a failsafe feature and some aircraft radios have the feature set to continue the 'last known signal' instead of having everything turn off. 
*Form Factor: Most people have a strong preference on the form factor of their radio. There are many different styles but the dual-stick and pistol-grip radios are the most common. Pistol grip radios are typically easier to learn but some people feel they lack the fine control of the dual-stick radios. In the end its usually a personal preference and with enough practice the differences are indistinguishable. 
*Functionality: Each robot's requirements are different. A simple wedge robot may only need two channels with a third channel enabling a weapon but some robot designs need even more channels or other radio programming features. 
Team Run Amok's [http://runamok.tech/AskAaron/radio_guides.html Ask Aaron] site is a good resource for additional information and troubleshooting. 
 
Common problems 
Since the radio sends a signal to the robot's Electronic Speed Controllers to drive the robot's functions, it can sometimes be difficult to determine if the problem is with the radio or the ESC. To make troubleshooting easier, solutions to common problems that affect the whole system are described here.
*Failsafe: 
*Signal Loss: 
*Not Binding / Connecting 
*Compatibility:
*Too Responsive:
*Controls Reversed:
*Only one motor responds:
*Robot hums or whines:
*Robot won't stop moving:
