1. A surgical device, comprising:
a hand-held portion;
a working portion movably coupled to the hand-held portion for driving a tool;
a plurality of actuators for moving the working portion with respect to the hand-held portion in response to control signals, generated by a computing system, corresponding to a location of at least one of a bone and the tool to align the tool with a target having a pre-determined location relative to the bone, wherein each of the plurality of actuators has a travel range with a travel limit and wherein each of the plurality of actuators is mechanically incapable of moving the working portion to align the tool with the target if the required movement of the actuator would be outside the travel limit; and
an indicator for indicating when at least one of the plurality of actuators is: (i) within the travel range; (ii) approaching the travel limit or (iii) outside the travel limit.
