On the other hand, why would the bridge need to carry balls at all? Just put the bridge on the section of track that separates the reliable modules from the unreliable modules' loop. But I suppose if the bridge does nothing at all with balls (not (...) (18 years ago, 5-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)

(...) I am 100% thinking along the same line. At first I thought of simply stopping the ball lift and immediately raising the bridge, letting balls along the slope drain backward into a hopper, but after watching the bridge raise and lower, I doubt (...)

(...) Not long at all. With the 3'+ slopping double-beam track I had at BF '06, I think it only took less than five seconds for them to clear the end... and that was for a *very* shallow slope. Given the time it takes to lift and lower the bridge, (...) (18 years ago, 7-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)

(...) Heres a thought. Just have the slope going in the other direction. That way when it lifts, the balls keep rolling the same direction. (Faster and efficient!) If the raising is too bumpy, just find a way to place a third or fourth overhead rail (...) (18 years ago, 7-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)

(...) One down side here, is that the "ball-lift" must be shut-off when the bridge is raised, and the controller for the ball lift is on the "bridge" (other) side of the opening. But, along those lines, if there is a bin to catch lose balls, the (...) (18 years ago, 7-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)
