Mr. Rush,
You have jumped to a number of assumptions as well. The original poster and I have communicated privately and I am merely adding to the discussion for the benefit of those others that are reading this thread. Don't forget, there are many who lurk here who will gather wrong impressions if just reading uniformed posts. When someone asks for help (including you) I will give them as much information as I deem necessary for the original question(s).
As to the van door vs. drill, you have now taken it to another level as the drill motors draw between 95 and 100 amps depending on which factory they came from. Should there only be two motors then the issue with the power source remains but is lessened over the short term. Beyond about 4-5 minutes of run time, the battery will still fall to below the required eight volts at which the RC ceases to function or switches to backup battery. Since no backup battery is visible I can assume that the RC is an early version and will simply shut down during these high current situations and the result is a four to five second reboot. I believe it was stated earlier that this is a 2001 robot which would put the RC in the pre backup version.
As to the composition of the cleats, being plastic or rubber or aluminum does violate 2008 rule R06 "Traction devices shall not have surface features such as metal, sandpaper, hard plastic studs, cleats, or other attachments". Since this important for students thinking about their 2009 robot, I included it in my previous discussion.
As to gathering knowledge, is it better to fail and fail and fail yet again or ask and receive knowledge from one who has experience. It seems like the old adage "Don't reinvent the wheel" applies.
