Delta Mechanism with Enhanced Torsional Stiffness

Case ID:

C13205

Disclosure Date:

8/11/2014

Unmet Need
This invention pertains to an improvement in the Robotic ENT Microsurgery System (REMS). The REMS robot uses a delta mechanism to provide translational degrees of freedom. Though the delta mechanism offers a lot of advantages, particularly in reducing the weight of the robot has to move, it also suffers from weak torsional stiffness.

Technical Details
Johns Hopkins faculty member and medical robotics pioneer, Dr. Russell Taylor, has developed an improved feature of a delta mechanism used in industrial robots. The delta mechanism is a common parallel design for industrial robots, however its stiffness against torques is low. The disclosed invention presents a way of stiffening the delta mechanism against torques.

Stage of Development
Dr. Taylor has constructed a prototype manipulator including the delta mechanism and has performed a number of evaluation experiments on phantoms and cadavers.
