Continuous Robotic Knee Joint

Tech ID: 29798 / UC Case 2016-692-0

Summary

UCLA researchers in the Department of Mechanical & Aerospace Engineering have developed a continuously rotating robotic knee joint that would enable broader range of motion and increased stability.

Background

Limbed locomotion of most modern day robots have many physical limitations, and one of these is the range of motion of their joints. Joint limits can restrict the type of locomotion possible for a particular task. New UCLA technology replaces a traditional robotic knee joint with a continuous joint to provide innovative methods of locomotion.

Innovation

UCLA Researchers have developed humanoid robot that has a continuously rotating knee. This allows the joint to rotate a full 360 degrees and allows the joint to act as a stability point. In the case of a humanoid robot, the knee would be able to become an additional foot. This joint provides increased stability and versatility over traditional knee joints.

Advantages

  • Provides traditional limbed robots with more stability without decreasing versatility
  • Removed limits of traditional knee joints 
    • Allows robot to traverse higher obstacles 
    • Allows robot to rapidly move through rough terrain 
  • Additional stability points allow robot to remain statically balanced 
  • Robot can step on or over obstacles with less energy and minimal sacrifice in stability compared to traditional models
