Re: Disk brakes
Team 38, The Nonebots, used a disk brake on their arm in 2005. If you look in the linked photo, you'll see if just below the middle student's left wrist. IIRC, it worked pretty darn well, as they were a regional champion is Rochester (?) that year...

Re: Disk brakes
We have been using disk brakes for 3 years now, and they are really good to have. We didnt use the ones from a bike though we went out and bought some from a go-kart shop.

Re: Disk brakes

Re: Disk brakes
I have an omni drive proof-of-concept machine i'm working on right now, uses just 2 motors to do swerve drive and am using a solenoid to actuate the disc brake on a part of the machine.
Yes, yes i know that you can't use solenoids, but if anybody ever needs to have a way to do it easily outside of first i've found it works very well. We used got our disc brake and the caliper for it from Northern Tool at a great price. Also an awesome place to get big tires cheap too, among other things... its like harbor freight on steriods for some stuff  -Q

Re: Disk brakes
Brakes are actually a really good idea. I can think of quite a few instances where 4 locked wheels on a robot with heavy traction wheels could put up quite a defence against another robot trying to push it!

Re: Disk brakes
I can think of a pretty easy and cheap way to fab up some disc brakes.
Get some sheet aluminum, or round aluminum, cut out discs, drill them on a press, then make some sort of rubberized pad and a caliber. Probably would cost around $50 for 4 wheels depending on how you did it. Darn, now I want to go try it!
