Re: Over weight robot
A few things:
-Replace all of the sheet metal with similar thickness polycarbonate. -I can't see your battery mount, but based around the way the bot is built, it's probably overbuilt, but easy to modify -Drop all the clips that hold in the pneumatic tanks and use 3-4 zipties. Best of luck! |

Re: Over weight robot
It looks like you have a lot of fasteners on your robot. If they are stainless steel or steel. if they are you could replace a lot of those with nylock or aluminum.
Hope this post helps. ![]() |

Our robot also has a weight issue... How strictly is the 120 pound rule enforced?

Re: Over weight robot
It's a rule in the Game Manual. If you don't meet the rule, your robot is illegal and thus can't compete. And yes, all robots are weighed, at each competition.

Re: Over weight robot
You have got to be kidding me.... How heavily enforced is the bag and tag rule?

Re: Over weight robot
It is also a rule...it doesn't matter if it is enforced heavily or not. What matters is that it is an official FIRST rule, which all teams should follow. If you break the rule, your robot is illegal. All other teams are stopping work on their robot today...why should you be an exception?

Re: Over weight robot
You should actually aim to bring your robot in a few pounds under 120 so that you can make minor modifications at the competition. The 120 pound limit is strictly enforced and you can be reinspected at any point.
Yeah, I know... that advice really helps now, doesn't it? If you have four CIMs in your drivetrain, you can solve most of your problem just by getting rid of two of them. Yes it will affect your performance... but perhaps not by as much as you fear. I've found that replacing all the steel screws holding the electronics down with nylon screws can shave about a pound. The best weight loss program I've seen dropped 30lbs from a robot on Thursday, at an event. We've done ten or fifteen pounds, but it took us a weekend of build time. One thing you might want to consider is rebuilding one of your components out of lighter weight materials. You can do this as part of your "withholding" limit. Then you could unbolt your current "heavy" unit and replace it with the "lighter" unit at the event... Jason |

Re: Over weight robot
I removed 8 lbs of redundant and oversized hardware from a robot once. Remove large screws that aren't needed, replace screws holding on light components and other items with zip ties, and cut down pieces of aluminum that have excess length that aren't holding anything. Holes only go so far...
