We are having a major problem with our chipphua motors. When we try to drive the robot, if you go any faster than just barely moving, the speed controllers controlling the motors begin randomly turning on and off. This happens with even greater frequency when we try to run the motors in opposite directions to turn. We had the same problem last year, due to a short so we checked every single connection on the robot, replaced the speed controllers, and even the control board. Then we thought that the problem could be due to not enough reduction on the motor, since we used the reduction from the motor gear and the gear that came in the kit, and then atached that gear to a shaft driving a 23 tooth sprocket connected by chain to another 23 tooth sproket, which drove the 4 inch diameter pulley for our 2 inch wide treads. We thought this might have been the cause since the robot ran fine when it was up on blocks, no trouble turning or going full speed. To test this out, we removed our top section containing the bulk of our weight, about 90 pounds. With the 40 pound base, the motors still gave us touble when driving the robot, but worked fine when all load was removed from the tread drive. Has anyone else had a similiar problem or have a solution?
