 FIRST is similar to real life in that nothing is perfect and you have to deal with the circumstances as they arise and make the best of it! - Sean_330 [more] |

Re: Interesting/Cool Scaling Mechanism Designs
How does 4060 ensure that as the balloon thing collapses when lifting up, that it stays within the 15" extension zone?
It doesn't look like it sticks too far out in the video but also seems like it could potentially end farther out. I'm sure they thought this through so I'm just curious as to how they're solving that issue. I would think some strong attached to the middle with a spring or something could guide it to collapse back into the robot.

Link to a match where both us (226) and 217 scaled. We have a multi-stage lift made using rev-rail, and is connected to a series of constant load springs. The bottom of the mechanism is attached to a winch. At the end of the match the driver reverses the winch, allowing for the mechanism to go up, and then brings it down to scale. We used 2 cims for the scaler, and a back drive gearbox with a servo. I'm not sure about 217's scaler, but I think it uses similar tactics with a lock to firmly grip the rung.
