 Whether or not your team has the technical mentors, as long as your kids are still inspired by the adult technical mentors of other teams, and get the picture that we're trying to portray in this program, the best that you can do is the best you can do. Do it, and be proud of your results. - Beth Sweet [more] |

Re: pic: Cooney 269's Worm Crab Gearbox Interior
The problem with Worm drive on the main wheels is that Worm drive is very ineffecient. What this means is that it draws a lot of battery power to drive the wheels. Last year team 772 . used a worm and wheel and at the start of a match could drive up last years ramp- ( the ball shooter ramp) . but at the end of the match after they run the battery down for 2 mins. could not.
Worm and wheel is good for high reduction ratios and if the worm pitch is choosen properly- self locking. - that a bout it.- they are generally high is sliding friction and cannot coast. If you want a "coastable" robot - do not use it. In a nut shell- don't waste your time.- if it was good all the good teams would be using it.!
