Direct training of robots using a positional deviation sensor
MetadataVis full innførsel
A device and system for physically guiding a manipulator through its task is described. The device consists of inductive, contact-free positional deviation sensors, enabling the rcbot to track a motion marker. Factors limiting the tracking performance are the kinematics of the sensor device and the bartdwidth of the servo system. Means for improving it includes the use of optimal motion coordination and force and velocity feedback. This enables real-time manual training of high-performance manipUlators. Multidimensional, non-linear measurement equations for the sensor system are developed, and their inversion described.
