Re: Al's Annual Inspection Thread

Third Installment...
Well I hope everyone finally got their robot bagged. For those of you attending district events, you have the ability to open your bag, under certain specific conditions, to perform additional work. Please check under Robot Transportation in Section 5 of the manual. Be sure to document your bag open on your Robot Lockup Form.
Electrical Continued...
1. Visibility of components. This is really an important one. The robot rules require that electrical components be visible for inspectors to see values and wire types as well legal motors etc. We will make every effort to check these items but if you make them invisible it will be difficult to get through inspection. We must be able to compare breakers to wires and check wiring of the radio, cRio, etc. I just read a team post this morning about electrical students wiring with undersized wire that smoked and melted due to being the wrong gauge.
2. Wire color code must be followed. I get the complaint every year that the automotive industry uses different colors than those specified. Yes, but the robot rules are very specific. The Q&A also answered this question earlier in the season. You must use the color code supplied in the Robot Rules.
3. Motors. Only the legal motors please, those listed in R29 of the Robot Manual. Fisher Price and Globe motors are no longer legal motors.
4. Servos. You may use servos but they are limited by power output to 4 watts@6 volts based on the industry standard, Stall Torque x No Load Speed.
5. Main breaker accessibility. This is an important one. Please do not put your main breaker behind your signage or inside a hole that my hand cannot fit through. Marking it's location is a huge plus. When your robot sets itself on fire, we want to shut it off. If we can't get to the main breaker to turn off your robot, it may self destruct. We may also suggest that you move your breaker to a more secure location if we think it may actually be in a position that it will get bumped off by another robot or the ball.
