1. we have two shells. The first is made from .225" Grade 5 Titanium with interchangable S7 and O1 Toolsteel Teeth (depending on which tooth) and the second is made of 1/4" 6061 Aluminium (aircraft grade) with stainless steel teeth.
2. Two S28-150 Magmotors power the spinning shell and another two power the four wheel drive.
3. The most critical lesson I have learned is have ALL your wires running through the middle of the robot. We had them running along the outside edge two years ago and when someone punctured our shell a peice of our own shell went through and ripped some wires out. we lost power immediately. having redundant wiring is not such a bad idea either
I thought of this at least a couple of years ago, but I didn't post because I didn't want to give Dave any fiendish ideas. He has enough without our help. - ChrisH [more]
