FIRST Team 2620 Wheel Teaser, You'll like this ;D

[Lee Reed]

Ya, its got some problems. If the angle on the latch mechanism is too great the latch may let go when we don't want it to. If the angle is too small the window to reset will be too small & will miss. We are still working on that. But in any event this has been a great learning experience. Some day these kids will rule the world.

Could you actuate a reset by driving against a wall, if you do this do the wheel modules ride up as the torque is transferred from the wheel to the module due to the wheel stall? If this is the case, then you could both reset and deploy them at the same time, as soon as you came into contact with the bump, eliminating the need for a latch, or a lifting mechanism all together.
