REMOTE-HANDLING TASK PERFORMANCE AS A FUNCTION OF INDEXING VARIABLES
Abstract
Three variables in remote-handling operations were studied: mode of indexing actuation, rate of angular indexing, and task distance. A CRL Model 8 Master Slave Manipulator was used by subjects performing a positioning task which required angular indexing (mechanical motion was locked in the Y axis). Actuation of indexing was either by a finger trigger or a foot pedal, an at one of three different indexing speeds. The task involved positioning objects at one of two distances from the operator In terms of speed of performance, the foot-pedal and fingertrigger controls were equal. However rate of learning and accuracy of performance were greater with foot-pedal actuation. Task efficiency, measured in speed of performance, increased directly with indexing speed at the far-task distance. This effect was not noted at the near distance.
