Re: FP 9003 vs 9012 (was Attention Robot Inspectors:)
Well, hopefully we were the only team that got bit by this mistake. We used 9003s in our prototype design, not thinking there was a difference. The design worked great, and we were lifting 160 pound bots on our ramps with no problems in our lab. Thursday morning at the Phoenix Regional, a student reminded us we had to use the 9012s so we made a quick swap out on the bot, thinking there would be no big deal. After the first few matches of not being able to lift anyone we were going nuts trying to figure out what happened..?? After two days of trying to figure it out, we realized that the current limiter was cutting us off on any bot over about 100 pounds. That being said, our primary design/plan of lifting 2 bots per match securing 60 points, got us 0 bots per match. We were dead in the water and useless at the Phoenix regional because of it. Just a valuable lesson for anyone trying to lift bots or making any last minute switches on these motors.
