Session 8: Robot Rules
This section lists the main rules and requirements for the design and construction of a “competition legal” robot. Robots must meet all of these criteria to pass inspection prior to the beginning of each tournament. This list is just a summary. There is significantly more detail for each of these rules listed in the game manual.
The Robot
<R1> Each team can have only one robot. You will make changes to this robot throughout the season.
<R2> Your robot must pass inspection before being cleared to compete.
<R3> Robots must fit in an 18″ x 18″ x 18″ volume, checked with the official VEX sizing tool.
<R4> Team numbers must be displayed on robot license plates. The plates must be placed on at least 2 horizontally opposing sides (not the top).
<R5> The robot must let go of scoring objects after the match (without requiring the robot to have power after a match).
<R6> Robots must use only one VEX V5 brain.
<R7> The on/off power button on the V5 brain or battery connection must be accessible without moving or lifting the robot.
<R8> Teams must use VEXos version 1.1.5 or newer firmware.
<R9> A “Competition Template” must be used in your program with “when started,” “when driver control,” and “when autonomous” sections
<R10> Motors are limited and the total combined power cannot exceed 88W. VEX sells both 11W and 5.5W motors and they can be used in any combination.
<R11> Drivetrain Motors are limited and the total combined power cannot exceed 55W. These motors cannot provide power to any mechanism not a part of the drivetrain.
<R12> Robots can only use one V5 battery to power the V5 Brain. (You can use a rechargeable battery pack plugged into the V5 controller during a match.)
<R13> Robots must use the VEXnet system for wireless communication.
<R14> The V5 radio should be mounted so that no metal surrounds the radio symbol. This will help prevent robot communication issues.
<R15> One or two controllers can be used to control a single robot.
<R16> Robots are built from the VEX V5 system using only official VEX V5 components (unless specifically noted within these rules). You can check the V5 Competition Legal Parts List.
<R17> New VEX parts released during the competition season are considered legal unless otherwise noted.
<R18> Some materials are prohibited. Robots must be safe. They should not have mechanisms that could damage field elements, scoring objects, or other robots. No 3D printed parts.
<R19> Certain non-VEX parts are allowed (non-aerosol-based grease for lubrication, hot glue to secure cables, 1/4″ diameter or smaller string, bundling material for cables and pneumatic tubing, rubber bands, zip ties, anti-slip drawer liner…).
<R20> Custom V5 smart cables can be built with non-VEX connectors as long as official smart cable stock is used.
<R21> A limited amount of tape can be used to secure wires, label, decorate.
<R22> Certain non-VEX fasteners can be used (screws up to 2.5″ long, shoulder screws, nuts, washers, standoffs, spacers).
<R23> Non-functional decorations are allowed as long as they don’t affect robot performance.
<R24> A limited amount of non-shattering plastic (up to 0.070″ thick) can be used. Robots are limited to 12 individual pieces no larger than 4″x8″. These include polycarbonate (lexan), delrin, acetron GP, POM, ABS, PET, nylon, and polypropylene.
<R25> Pneumatics are limited to a maximum of 2 VEX pneumatic air reservoirs charged to a maximum of 100 psi.
<R26> The VEX Pressure Gauge is required if your robot uses pneumatics.
<R27> Most modifications to non-electrical components are allowed.
<R28> No modifications can be made to electronic or pneumatic components.
