I was wondering if anyone had built a small tank drive like ev. From my use with chairs, I dont know if its the small motors or retarded programming, but they go with the slope. So, driving on the edge of the road, it pulls to the gutter. On a chair, you just move the joystick to about 10 oclock position to go in a line, but with less speed then before.
My idea was to use a gyro to sense left and right movement and maybe rig this to the controls so it can compensate for this or for quick jerks in direction like if you hit a pot hole with one side or rut. Just an idea jeff richmond, va http://www.wheelchairmodifications.org
