Abstract
Apparatus and related methods for assisting tool use includes one or more motors, a wrist support and a shaft coupled to the one or more motors. The shaft includes a coupling to couple to a tool to enable a user resting a hand with the wrist on the wrist support to hold and manipulate the tool with one or more fingers. The apparatus can include a controller configured to: receive position data indicative of a position of an active end of the tool; receive constraint data indicative of one or more regions of space in which the active end should not be positioned; and process the position and constraint data to control the one or more motors to bias the active end out of a region indicated by the constraint data when a position indicated by the position data is within the region indicated by the constraint data.
