1. A system for supporting an arm of a user while using tool, comprising:
- a harness configured to be worn on a body of a user, the harness comprising a shoulder harness configured to be worn over or around one or both shoulders of the user including a first pivot point above the shoulder of a user when the harness is worn by the user;
an arm support comprising a first arm support segment pivotally coupled to the first pivot point, a second arm support segment pivotally coupled to the first arm support segment for supporting an upper arm of the user, and a third arm support segment pivotally coupled to the second arm support segment for supporting a lower arm of the user;
a linkage coupled between the first arm support segment and the third arm support segment such that a vertical angle of the third arm support segment is not affected by rotation of the second arm segment;
a tool mount coupled to the third arm support segment; and
a first set of compensation elements coupled to the second arm support segment for at least partially offsetting a gravitational force acting on the upper arm, and a second set of compensation elements coupled to the third arm support segment for at least partially offsetting a gravitational force acting on the lower arm.

Abstract
Systems and methods are provided for supporting an arm of a user while using a tool that include a harness configured to be worn on a body of a user; an arm support pivotally coupled to the harness for supporting a user'"'"'s arm; and a tool mount on a free end of the arm support for receiving a tool such that the tool is manipulatable by a hand of user'"'"'s arm supported by the arm support. One or more compensation elements may be coupled to the arm support and/or the tool mount for at least partially offsetting a gravitational force acting on the user'"'"'s arm and/or the tool received on the tool mount.
