Abstract : Determining a robot's reachable volume is important both for operator safety and for ease in the design and specification of experiments. This was the main focus in establishing the workspace for the Force REFLecting EXoskeleton (FREFLEX). Cartesian position data are collected by maneuvering the FREFLEX pistol grip manually. A program written in C first collates these coordinates into 'slices' of data. Then, a second algorithm determines the outer boundary of each slice. Stacking the adjusted data slices together provides a clear definition of the maximum FREFLEX boundaries. Additional graphical manipulation through workspace rotation enhances both the view and worker understanding of the FREFLEX work area.
