<p>Abstract The present invention relates to a reciprocating mechanism. In particular, the invention relates to a reciprocating mechanism suitable for use in a robot, wherein the robot is capable of performing a drumming action. In specific embodiments, the mechanism includes: (i) a substantially fan- or wedge-shaped member having a pivot, a follower end and a distal end, wherein the distal end includes a plurality of teeth; (ii) a guide cylinder having a serpentine guide means around a curved surface of the guide cylinder, wherein the follower end engages with the serpentine guide means such that as the guide cylinder is rotated the follower end traverses the curved surface; and (iii) a central pulley member having teeth that mesh with the teeth of the distal end; wherein movement of the follower end is translated into movement of a distal end via the pivot of the fan-shaped member, and wherein movement of the distal end causes movement of the central pulley member via their meshed teeth.
