Control and Power SUMO Wrestler® and Other Robotic Vehicles! Portable! Battery Powered!
The KELVIN® SUMO Car Wrestler® Controller is a wired controller that can be used to add remote control. Ideal for testing vehicles with no waiting - have a few in the classroom or students can even take it home! Connect to four motors - two to drive and two for flippers.
For battery operation,  'D' batteries are required (Alkaline, #220015 or Ni-Cad, #220027).
For a classroom competition, we recommend the yellow KELVIN® Power Supply, #841051, which requires no batteries and has constant voltage and current.
