Abstract
An example robotic joint may include a first cam and a second cam. The robotic joint may also include a first actuator configured to contact the first cam, a second actuator configured to contact the first cam, a third actuator configured to contact the second cam, and a fourth actuator configured to contact the second cam. The robotic joint may also include a first coupling link configured to couple the first cam to a first drive shaft link, and a second coupling link configured to couple the second cam to a second drive shaft link. The robotic joint may also include a drive shaft rigidly coupled to the first drive shaft link and the second drive shaft link, wherein the drive shaft rotates about a first pivot axis when the first and third actuators and the second and fourth actuators act in concert.
