These ties are used all over our robot to secure things. They hold all of our wires. We use them to secure our GoPro Camera (in tandem with the GoPro mount). Also, they are great for keeping pneumatic tubing straight. You can sut them on the band saw to fit them in tight places. The adhesive is really strong once firmly pressed on, and they have screw mounts if you wanted to use them for heavier things, though we mainly use them for routing. Some of our programmers use them to run cables in their computer cases at home, and I use them on my boat, exposed to the saltwater, without incident.
Also, make sure you buy good Zip-Ties that don't break when pulled tight. We used crappy zip-ties to hold down are pneumatics tanks, and all but one snapped. Luckily we didn't lose them onto the field, but now our air tanks are held by ~3/8" wide zip ties. By the way, in my personal opinion, zipt ties are the quintessential tool. We use them for all of our routing. They hold down all of our pneumatics except the compressor. We zip tie our battery connector each match so we don't lose power. We even made an emergency repair on our robot and zipped down the C-RIO, which is pretty darn secure now. Additionally, if anybody saw the picture of our shooter from last year, specifically the one where it snapped off and fell at Duel on the Delaware, we made an emergency repair during Elims, and held in a ~20 lb shooter with only zip-ties. Surprisingly, the autonomous worked, though since it was the lazy susan bearing that failed, we couldn't use our turret.
In short, Zip Ties and Square Tie Downs are awesome.
