Update on System for Robot-Assisted Microsurgery

Two reports present updated information on a robotic system that extends the dexterity of a microsurgeon. The system was described in two articles in NASA Tech Briefs, Vol. 21, No. 10 (October 1997); namely, "Telerobot Control for Microsurgery" (NPO-19823), on page 46 and "Force-Feedback Device...

Briefs: Robotics, Automation & Control

Robots with multiple-link arms that could reach through narrow openings into hidden cavities are undergoing development. Called "multifunction dexterous boro-robots" (MDBRs), these robots...
