Abstract

A robotic device for operation in association with an appendage of a user, wherein the appendage of the user has an endpoint, the robotic device comprising: a base; and a robotic arm attached to the base and having an end-point, the robotic arm having at least two active degrees of freedom relative to the base and being configured so that when the base is appropriately positioned relative to a user, the reference frame of the robotic device is oriented generally similarly to the reference frame of the user and motions of the endpoint of the appendage of the user are mimicked by motions of the endpoint of the robotic arm.
