Merx Mini Sumo Robot – Solarbotics Sumovore Robot Kit
My first mini sumo project which is made at 2005. Beautiful robot kit from Solarbotics. I changed It’s motors to slower model. Slower motors have more torque. Changed wheels with silicone bands.
It works with 6 Cells of Alkaline batteries.

Motors
They are Solarbotics GM2 model motors. all motor gears made from hard plastic so I don’t recommend for new designs. It has 46 rpm and 56 oz-inch stall torque at 6V.
Motor’s reduction ratio is 224:1 It’s very high! Actually not for today’s mini sumo robots.
Wheels
Wheels are standard wheels from mini sumo kit. I added two brass weights for more wheel traction. Additionally, wheel’s outer rings are made from 20 shoreA softness silicon.
