I believe the conclusion was that it was probably legal to use.

Burgabot,
Nice idea! Yes they are called slip rings and FIRST has ruled that they are acceptable this year if they fit the flowchart and they must be included in the robot inventory price limits. They are very expensive pre made but I expect some teams to come up with homemade alternatives. BTW, your car alternator uses slip rings to supply current to the field coil. I am waiting to see if someone adapts a part of an alternator for use on their robot.
