Abstract

 

Graphical Singularity Analysis of Planar Parallel Manipulators

 

Parallel manipulators have various advantages over serial manipulators, such as high payload-to-weight ratio, high accuracy, and high rigidity. However, they also have a few drawbacks such as a relatively small workspace, relatively complex kinematics and a failure while in, or close to singular configurations. In these configurations, the mechanism tends to lose its stiffness while gaining extra degrees of freedom.

 

In this talk I will present a new method to graphically determine the singularities of planar parallel manipulators. This method integrates screw theory tools with the field of graphical statics (based on J.C. Maxwell's reciprocal figure theory).

 

 

This seminar is presented in partial fulfillment for the requirements of the degree of Master of Science in Robotics.

 

Committee members: Howie Choset, Alon Wolf, Matt Mason, Aaron Greenfield.
