• Length: 9.75cm (3.84")
• Height (ground to top of standoff): 3.77cm (1.48")

• Motors: 4x 35:1 Spark Gearmotors
• Wheels: 4x Cobra mini-sumo wheels.  Shore A20 polyurethane - the highest traction mini-sumo wheels available.
• Sensors: Includes three QRD1114 floor sensors (2 front, 1 rear) mounted to chassis.
• Scoop: 0.020" stainless steel angled scoop (can be legally sharpened to 0.010")
• Steel Ballast: An underweight mini-sumo is at a disadvantage!  This steel ballast keeps the center of gravity low.

Requires:

• Battery: 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.
• Electronics: In the chassis kit, the brains are up to you. You could use an Arduino Board or another controller.
• Sensors: Opponent detection can be anything you desire. Choose your sensors here.
• Motor drivers: (if not already included in your brain)
