Differential Drive/Tilter Mechanism
After about a week of work, I have finished modeling/animating a differential drive concept that could be used to power a tilter. This could also be converted to power a DR4B quite easily. I worked on this with some help from my fellow SCA member @ThirdDegree. It uses a differential to share motor power between the chassis and the tilter. When both motors move the same way, the fact that gears move in opposite directions force the mini 4-bar to move forwards, and the opposite when they are reversed. When the motors move in opposite directions, the gear ratios force the 4-bar to stay stationary, as the motors are trying to pull it both ways, but at the same time rotate the gears, spinning the wheels.
