Types of Drives?

Its been worked on, and should actually be mechanically simpler and much more robust than last year's drive. Of course, we will only go ahead if it is consistant with our strategy, which will be decided come January.

The programming will be tough, but thats not my deptartment (i'm just the lead designer). Control should be a breeze. If we manage to get the solid-state gyro online enough to give us a consistant heading so that pushing the joystick north, regardless of the facing of the robot, will cause the robot to move north. and same with all the other directions. With a twist-stick joystick, we can add translational and rotational movement all into one hand . . . it is a good plan, I think. We will see. The biggest problem will be to make the chips and drills run at the same speed not only at 100% throttle, but at all the various percentages in between. Like I said, we will see how things go.

Getting the Chips and Drills to run the same all the time is just in our gearing. You have many options to that.
