This video demonstrates the use of Virtual Fixtures in Robotic Laser Surgery. Virtual Fixtures are used to keep the laser fiber from touching the kidney. In addition, these fixtures assist the surgeon in tracing a tumor by creating a margin around it.

This video shows the Raven II moving to a series of points.  Movement is automatic, and to a pre-determined point.  Each movement is triggered by a human operator pressing a keyboard key.

This is the fastest we’ve seen the Raven II move (on purpose!).

Andy Lewis demonstrates the effectiveness of gravity compensation on Shoulder joint (joint 0) on both arms.

Gravity compensation is expected to improve controller performance.

Thanks Andy!
