Abstract

First second and third drive units for a mechanical manipulator are located on a support. An articulated arm assembly extends from the support and includes a first member pivotally connected to a first pivot axis on the support to form part of a first lever-parallelogram having a first lever and also part of a third lever-parallelogram having a second lever. A second member is pivotally connected at a second pivot axis to the first member and forms part of a second lever-parallelogram. A third member is pivotally connected at a third pivot axis to the second member and also forms part of the second lever-parallelogram. The drive units are operative to drive the first member and the first and second levers so that rotation of the first and second levers through first and second angles produces rotation through the same first and second angles by the second and third members.
