ABSTRACT:
A robotic apparatus, and components thereof, which is characterized by a high degree of modularity, enabling complex robotic mechanisms to be assembled on a customized basis from relatively standardized components on an efficient and economical basis. Individual numbers of a multi-axis device may be comprised of inverted channel-like support members, cut to predetermined length and provided at the extremities of their flange walls with opposed, longitudinally extending track strips. A movable carriage mounts series of guide rollers engageable with and guided and confined by the track strips for movement along a predetermined axis defined by the support member. A drive sprocket, driving by a digitally controlled stepping motor, with a drive sprocket, is mounted at one end of the support member and an idler sprocket at the opposite end. A discontinuous length of gear belt material is trained about the sprockets and clamped at each end to the travelling carriage, whereby the carriage may be precisely positioned on its support member by controlled step-wise rotation of the drive motor. A plurality of such component units may be assembled in a cascade fashion, with the support member of one stage mounted by the movable carriage of the previous stage. The successive stages may be mounted at right angles, to provide for manipulated motion along a combination of X-Y-Z axes, for example, or some of the units may be disposed at different angles.
