Our rookie year last year wouldn't had been successful if it would not have had ZIP-TIES. They are legal on robots and you can do anything with them. Got a loose part? zip tie it. Need some extra support? Zip tie it. Got a robot accessary to add to suprise the competition? Zit tie it! Our Light and tether were both held on by zip-ties!
Oh and get as many varieties as possible.
They also work well at keeping all that wiring together and in a nice tidy order.

ther are probably 80 zip ties in that one picture. I will say again that if you really need something, it will be zip-ties. We saw many teams who had wires every where, and when they went to work on their robot they had to be careful of all the wires. And plus it makes the electrical inspection easier.
