(...) 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, (...) (17 years ago, 7-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 (...)

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 (...) (17 years ago, 5-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)

(...) You'd need a hopper to store balls that arrive while the bridge is raised. You could probably rig a gate/door onto it that is open when the bridge is down and closed when the bridge is up. Or the entire hopper could tilt backwards with the (...) (17 years ago, 5-Feb-07, to lugnet.robotics, lugnet.org.us.laflrc)

| | FLL at Science Central

This weekend, I was working on a FLL robot for the Science Central event in a couple weeks. That went well. It's not 100% reliable, because it's hard telling how many atoms are coming off the table, and sometimes the stain-resistant fabric just (...) (17 years ago, 5-Feb-07, to lugnet.org.us.laflrc)

I suppose this doesn't have to really be for the GBC only, but that was why I decided to build it. I've been playing with this idea since Brickfest '06 when Steve Hassenplug suggested a way to go in & out of the GBC area without crawling under the (...)
