Re: Caster Mechanism

In 2002 Team Paragon also used a castor option to add 2 wheel steering behavior to our tank tread drive, which of course was a bear to steer & overheated the motors when turning a lot.

We used a seat motor & cords pulling a couple of flaps with castor wheels mounted, one in each corner of the chassis. It worked great, outside the 4 second activation time - As noted above, worm drive motors llike the seat & window motors take about that much time to lift 60 lbs.

Depending on the game dynamics, I would lean to either using a small pneumatic cylinder & pre-charged onboard air tank(s) without the compressor, or a fisher price gearbox or similar driving a cam.
It depends on how often you'd have to drop down on all fours for shoving matches.
