Abstract
A method of providing and maneuvering a mechanical arm relative to a base support includes the steps of pivotally attaching the proximal end portion of a first arm member to the base support for pivoting about a first pivot axis and pivotally attaching the proximal end portion of a second arm member to the distal end portion of the first arm member for pivoting about a second pivot axis. The method then includes driving the first arm member about the first pivot axis over a first angular range while simultaneously driving the second arm member about a the second pivot axis over a second angular range that is about twice the first angular range. The driving step may be accomplished, for example, by a mechanical drive which can be a hydraulic drive, a pneumatic drive or an electrical drive, such as a motor and gear drive.
