Good news, our autonomous is well on its way to completion. That robot in the picture isn't actually ours, but I've run extensive diagnostic tests to see exactly how fast the robot moves at full battery. The results:
Forward/backward: 13 inches per second
90 degree turn: 1.9 seconds
Claw rise/lower: 3.5 seconds
Of course, these results are all approximate, because it may not be the same fully charged battery every time, there could be mechanical errors that need fixing, etc. But it's a good estimation, and the courses should only require slight modification, depending on the box the program is directing the robot to.
