Re: Robot Lifting

We are going for 3-5 seconds for BOTH cable attachment to tower bar using a latex tubing snap bar, and then fast elevation of our bot with pneumatic cable tensioning speed, having saved all of our air for the end game ( our kicker is a winder that stores bungee tension & releases at any point during the wind up for variable kick power). If you can't make this happen quickly there is little time left to help partners get off the floor. Yeah, the two points is marginal, but 5 or 8 starts looking worth it.
The initial pneumatic pull up will be supplemented by having more winder pulling available at a stronger than pneumatic force levels from our same kick winder mechanism. So, if partners can get hooked on to our deployed hanging Kevlar cables, even with a mere static hook at top of their frame, we can still hoist them up off ground using our kick winder drive pulling at 250+ pounds of lift. Heck, we will even loan them a hook to mount on their frame before the match begins!
