Where to buy a 'Robot sized' CV Joint

Can you describe the application a bit more? Something as simple as a bellows joint or spider coupling may be sufficient. Torque? Application?

We are trying to steer powered wheels and we need the shaft to be able to have a bend in it and still transfer power. I first was looking for a U joint but one of our mentors said that it would not give us a constant power, in other words it would be 'jerky'.

For this year, you could probably get by with RC Monster Truck 4x4 front end units. Any good RC place should have the right stuff.

Typically for FRC robots teams build steerable pods (see swerve drive, or crab drive threads).

Teams with (in my opinion) excellent crab drive modules to benchmark would be 111, 496, 71... And many others. With the low torque and low skid traction this year, it might be a good year to try making a Crab drive module as typical failure modes should be less due to the lower loads.
