Fault tolerance of robotic manipulators is determined based on the fault tolerance measures. In this study a Jacobian of a 7DOF optimal fault tolerant manipulator is designed based on optimality of worse case relative manipulability and worse case dexterity from geometric perspective instead of numerical solution of constrained optimisation problem or construction of optimal Jacobian through a desired null space. The proposed Jacobian matrix is optimal and equally fault tolerant for a single joint failure within any joint of the manipulators.
