The concepts of Jacobian matrix, dexterity, manipulability and condition number have been floating around since the early beginning of robotics. These performance indices play an important role especially for optimal robot design. In this paper, we revisit these concepts for SCARA type robot and exhibit some surprising results that show that these concepts have to be manipulated with care for a proper understanding of the kinematics behavior of a robot. All obtained results for the performance indexes are graphically visualized. The presented graphical examples for the performance of a manipulator can be easily interpreted and also they can help in application and design of manipulators.
