ABSTRACT:
A flexible arm particularly a robot arm comprising a plurality of elements arranged in a series with adjacent elements in abutting relationship, said elements being interconnected via cables and if desired a power transferring actuating device. The arm has very good rigidity in the bending plane of each element and high torsional resistance together with low manufacturing costs. Each element is designed with opposed single or double-curved segments, or flat surfaces, or combinations thereof with the curved surfaces of each segment engaging the curved or flat surfaces of the adjacent segments, whereby the elements when actuated by the power transferring device have a rolling motion relative to each other.
