A universal joint is basically a flexible pivot point that transmits power through rotational motion between two shafts having misaligned intersecting axes. Purpose of this research is to propose and design a compliant mechanism, by analyzing the universal joint. The common design consists of two yokes, having a single bend angle, arranged with a pinion at right angles. Compliant version enables the joint with two bend angles, in two different planes. So as to achieve the compliance over the universal joint, kinematic analysis of common universal joint has been done and the results are generalized. For a common U- joint, pinion- yoke revolute have angular motion specifically for every bend angles. An important aspect of these revolutes is that, while in action they never go through complete cycles. In other words, each of these revolutes revolves only few degrees around its axis before returning to its original position. This angular motion is well studied for different bend angle combination up to 30 degree in two different planes. Based on the results, revolutes� angular motions are generalized, and compliance over the common universal joint is achieved. This compliant mechanism can find its application as a tool holder that can create complex profiles along with rotational motion in the field of manufacturing, robotics, surgical instruments etc.
