Things you only do ONCE!
 

I was just thinking about this while writing in another thread. This may prove to be just a thread to make people chuckle but it also may serve to remind teams about safety and best practices. So here goes a start for the list...

1. Touch a soldering iron to see if it turned on.
2. Carry a battery with one hand, and dropping it. (on your foot or on the ground)
3. Put the red wire on the black battery terminal.
4. Wire the radio to a normal 12 volt output on the PD.
5. Use a crescent wrench as a hammer. (power on or off, you choose.)
6. Hold a robot part in your hand while drilling. ( a variety of errors jump to mind)
7. Put a practice battery on the robot. (actually happens more than you know)
8. Build to last year's dimensions because "they never change".
9. Use a dremmel tool to grind right next to your custom 3D printed part.
10. Mount your bumpers upside down. (except teams 11, 111, 1111)
