ABSTRACT In this dissertation, fault-tolerance of redundant manipulators is thoroughly investigated. First, inherent relationship between the dexterity and fault-tolerance of single-redundancy manipulator is discussed. Both the manipulability and the relative manipulability are utilized for measuring the kinematic fault-tolerance of the manipulator with one joint failure. Furthermore, the relative manipulability is used for measuring dexterity loss resulted by one joint failure, and the relationship between the fault-tolerance measurement and null space vector of Jacobian matrix is established.
