Re: Bridge lower-er Motor? (HELP!)
We use a window motor with an arm and a catch. The arm contacts the ramp on the catch, so that the robots forward driving motion pushes the ramp down. This is achieved by having the pivot for the arm several inches above the top of the bridge, although the drive-train has about a 5-1 mechanical disadvantage it is still more than capable of pushing the ramp down.
