Re: gearing the minibot

Sorry for lack of info. It is mouted by just using some eletrical tape woulnd around it to have it large enough to be held by the mounts. The main issue I'm having now is now gearing it to make up for some of the power lost by removing the gearbox. I tried going from the smallest gear on the motor to the medium gear on the wheel today only to find that that did not provide enough torque to lift the robot and almost burned out a motor although I'm not sure if this might be because of the battery not being fully charged. Tomorrow I will try replacing the 80 tooth gear on the wheel with the 120 tooth wheel to see if that will provide enough torque to lift the bot up the bar And the gear ratio I am going to use is not for speed but for power as I feel the way the tetrix gearbox on the motor sacrifices too much speed so I am replacing it with a gear ratio to give it enough power to lift itself without sacrificing too much speed
