Q. First of all, the wiper motors and their grounding to the base. The list says this mustnt be so. Does this mean that i have to take apart the motor and cut/insulate whatever is grounding the case? simply mounting the motor on wood wouldnt work, as the chain still conducts electricity.

Answer:Correct you are. Insulation is important. You can get a grounded motor from Justin at OTC.

Q. Secondly, about the wiper motor. What guage wire must be used? I think right now it has some 14 guage 2 contact wire connecting it to the speed controller. It is what we used last year.

Answer: #14 is OK.

Q. The list says the electronics box mustnt have any exposed wires. I redid our electronics box over the summer, as it was a complete mess. I used quick-connect style terminals and ring terminals from my dad's work supply. They do not have the plastic casing, like the occra ones, though. I did a pretty nice job with the crimping and everything, and it looks quite pretty. would you consider this an exposed wire at inspection? Im sorta reluctant to replace them, because those things arnt cheap! If so, would electrical tape solve the violation?


Answer: Exposed wires or wires not in shielded connectors is a Problem if touches by a falling spike or victor causing a short. See inspectors at the competition early.

Q. On the list, it says the electronics box mustnt be altered and components can not be removed. Right now, we only have 3 relays inside (and we are only using 1!) and the automotive relay isnt in there because we arnt using that either. the RC, fuse panel, ground panel, main circut breaker, and all 4 speed controllers (3 being used) are all in there. Do i have to add the 5 more unused relays and the unused automotive relay to pass inspection?

Answer: Your control box should have the Min. parts as shipped last year. The extra spikes are not required.

Q. our electronics box is sitting on a piece of plywood, between some sheet metal and more plywood (so it isnt going anywhere) It is duct taped to the robot. is the duct tape sufficiant "mounting" for the elctronics box?

Answer: While duct tape is legal this year please make sure your robot is well built and not tacky looking. Duct tape was intended for emergency repairs not a construction standard.
