The Cobra conforms to the mini-sumo ruleset of RoboGames, the world's largest robot competition. Most smaller events uses these rules, but always check with your event organizer to make sure.

Part List

  • 1/16" thick garolite baseplate chassis (pic). Has mounting holes for scoop, standoffs, and 3 QRD1114 floor sensors (2 front, 1 rear).
  • 4x 50:1 Spark Gearmotors
  • 4x Cobra mini-sumo wheels.  Shore A20 polyurethane - the highest traction mini-sumo wheels available.
  • 3x QRD1114 floor sensors (2 front, 1 rear) mounted to chassis.
  • 0.020" stainless steel angled scoop (can be legally sharpened to 0.010")
  • 1x Steel Ballast:  An underweight mini-sumo is at a disadvantage!  This steel ballast keeps the center of gravity low.
  • 4x 6-32x0.375" screws for mounting the scoop, ballast and stand-offs.  Four for securing circuit board to standoffs.
  • 2x hex wrenches included for tightening screws and setscrews.

Compatible Parts

You will need

  • The chassis has a spot to accomodate a 26x53x26mm (2x1x1") battery.  Our Rhino 11.1V 360mAh fits perfectly and will run the robot for dozens of matches.  Some Velcro will secure it in place.
  • In the chassis kit, the electronic brain is up to you.
  • Opponent detection sensors can be anything you desire.
  • If your "brain" does not include motor drivers, two tinyESCs can be used (1 per side). They are very small and can be controlled using simple Servo PWM - only one data line each is required!
