Examples of spatial positioning redundant robotic manipulators that are optimally fault tolerant

Abstract: Abstract-It is common practice to design a robot's kinematics from the desired properties that are locally specified by a manipulator Jacobian. For the case of optimality with respect to fault tolerance, one common definition is that the post-failure Jacobian possesses the largest possible minimum singular value over all possible locked-joint failures. This work considers a Jacobian that has been designed to be optimally fault tolerant for a simple spatial positioning manipulator. It is shown that despite the … Show more

“…In consequence, several prototyping software packages, like [57,58], include dexterity evaluation as part of the robot design phase. In [59] the design of fault tolerant robots is tackled by means of kinematic robot design that allows the recovery after a locked joint failure. This is achieved imposing the largest possible minimum singular value of the Jacobian, which is a measure of dexterity.…”
