Rotatable joints may include one or more braking assemblies. The one or more braking assemblies may control a degree of movement of the rotatable joint to provide a range of damping. In some instances, the braking assemblies may include brake band(s) that tighten and loosen around a hub, or other rotatable member of the rotatable joint. The amount of braking, or tautness of the brake band(s), may be variably controlled to arrest the hub by different amounts. In some instances, the tightening of the brake band(s) around the hub may be controlled using linear actuator(s) and/or magnetic element(s). Implementing braking assemblies having controlled actuation may improve control of rotatable joints without adding cost, complexity, weight, or bulk.
