Mechatronic design efforts have been and continue to be heavily investigated in the development of robotic manipulator arms. However, little effort has been devoted to mechatronic redesign of traditional two-dimensional mechanisms which mechanical engineers get exposure to when they study subjects such as kinematics and mechanism design. In this paper a feasibility study for controlling the motion of the popular slider crank mechanism with appropriate sensing and actuation is elaborated. The results indicate that a variety of motion profiles can be derived from the same mechanism without involving any mechanical redesign. Many of the control approaches that have been heavily investigated in the field of robotics are readily applicable to such mechanisms. The synergistic combination of mechanical design, soft computing, sensing, instrumentation, and control is likely to bring about unprecedented versatility and performance levels in the hardware realization of machines based on these mechanisms.

Abstract Cam-modulated linkages are a combination of cams and traditional linkages. These mechanisms have the advantage of satisfying an infinite number of precision points for path generation and body guidance synthesis problems. It is possible to synthesize these mechanisms graphically; however, established graphical synthesis methods can be tedious and do not lend themselves to iterative mechanism design or optimization techniques. An analytical method for synthesizing cams for cam-modulated linkages using principles of conjugate geometry is presented. The method is valid for two-dimensional or three-dimensional mechanisms. The same method is used for followers undergoing complex motions. The method is applied to verify the synthesis of a high speed printing mechanism produced by Pitney-Bowes.
