[CRUSH-build] lifting with springs

[Bill Bennett]

This gives example information for the extension rate for an unloaded spring. Would be interesting to see a curve of the extension rate as a function of load, so we could compare the loaded to unloaded rate. We want the loaded rate to be fast enough (reasonable amout of time to lift at end of game) and the unloaded rate to be slow enough (safe).

  Here is a good explaination.  (see attached PDF)

    One of the ideas we're discussing is lifting the partner's robot with springs, for example, nitrogen filled gas shocks like are used in car trunk lid lifters. We'll have to understand how these are controlled, since if the lift is released with no load (no robot on it), it will still have to rise safely. Can we get one to study this?
