Abstract
In this article, we describe and demonstrate control algorithms for general motion constraints. These constraints are designed to enhance the accuracy and speed of a user manipulating in an environment with the assistance of a cooperative or telerobotic system. Our method uses a basis of preferred directions, created off-line or in real-time using sensor data, to generate virtual fixtures that may constrain the user to a curve, surface, orientation, etc. in space. Open loop virtual fixtures seek only to maintain user motion along preferred directions, whereas closed loop fixtures additionally guide the user toward a point, line, or surface. This article demonstrates and compares the effects of open and closed loop fixtures in both autonomous and human-machine cases.
