Re: How Would You Change Your Robot

Assuming we're going with the same basic design:
  • Decouple the pickup and shooter mechanisms. Our shooter springs were inside the arms that had our pickup rollers on the end, and this caused much weirdness when we wanted to pickup with the shooter cocked. If we had to redo it, I'd have gone with a more standard linear punch than our slingshot design.
  • Remove the open/close of the shooter/pickup claw. This didn't get us much except the ability to catch, which we never used once, and a LOT of headaches with our lead screw and sensor. We could probably figure out how to make it able to shoot and pickup with changing the openness of the claw.
In other words, I'd try and make our robot a lot more like the H.O.T. Team's bot - they certainly seemed to be one of the most effective implementations of the two-sided pivoting claw/arm/pickup/shooter design this year (which very few teams seemed to do!). Ultimately our biggest problems were trying to do too much and making our systems too integrated to the point that if one function failed, many others would as well.
