Abstract
A four degree of freedom manipulator which comprises a pair of elongate rigid legs connected by a joint. The joint acts as an end-effector or an end-effector is attached thereto, The legs effectively intersect at a point in the joint. The positioning end of each leg is attached to a two degree of freedom positioning mechanism that can position it in a two dimensional plane. The connection between the leg and the positioning mechanism has two passive rotational degrees of freedom. Preferably five bar mechanisms are used as the positioning mechanisms. The manipulator can control the position and orientation of an end-effector.
