The gearbox was built as a separate component to the actual robot. It uses 12.7:1 gear ratio to produce 94 gf x cm of torque and 1039 rpm. We used this gearbox to replace the original gearbox in the robot.
Because the first gearbox did not have enough torque, we had to rebuild the mechanism. Whilst rebuilding, we also tightened up the gears to reduce play throughout the mechanism.
As we began to test our gearbox and motor assembly onboard the trackbot, we quickly realized that the gearbox had too much play, and was not delivering enough torque to the wheels. To combat these issues, we decided to rebuild the gearbox to a setting with more torque.
We also realized that the motors were spinning in opposing directions. To combat this issue, we decided to rewire the motors.
Today, we programmed and refined our bumper sensor, optimizing it for head-on collisions with objects. We also finished programming the accelerometer, measuring x,y, and z acceleration. Furthermore, we began programming our light sensor to detect the black line that it will be following in the final test.
