Virtual Fixture Control for Compliant Human-Machine Interfaces
• Virtual Fixtures provide motion guidance in human-machine cooperative manipulation.
• Position errors due to robot compliance and hand dynamics degrade virtual fixture performance.
• Newly developed Dynamically-Defined Virtual Fixtures consider joint compliance and human hand dynamics.
• Two user experiments demonstrate significant performance improvement with this method.
