Weight bonuses do NOT stack. If you have any questions, feel free to ask on our discord.

For Plant:

   We used a modified weight bonus system that encourages technological innovation:

      Non traditional locomotion(shufflers, gyro walkers, bristlebots, etc.) = 1.25lbs

      Swerve drive and true multibot(50/50 or 51/49 split) = 1.5 lbs

      True walker (at least 3 individually controlled DOF between all legs) = 2 lbs

   The only allowed plastics are PLA(+), PETG, ABS, and ASA.

   COTS parts are allowed where necessary.

   Custom TPU wheel cores are NOT allowed.

   Under no reasonable circumstance should a non printed component be impacted in a way which protects the robot

   Thermal post processing of parts (salt annealing) is not allowed.
