"This experiment was undertaken to investigate the ability of Master-Slave Manipulator (CRL Model 8) operators to identify the slave hands and their movements with corresponding components and functions of the human body (specifically forearm, wrist and finger movement). A handling task involving rearrangement of blocks was devised to be performed under two different conditions: (1) with standard slave jaws (red jaws) and (2) with slave jaws modified so that the jaw corresponding to the thumb of the operator was green. The task was performed at distances of 9 inches, 36 inches, and 63 inches from the radiation shield. Work time as a function of task distance was investigated and work ratios, based on mean time scores for direct handling vs. remote handling, were determined."--Abstract
