摘要

The use of robotic manipulators in remote and sensitive areas calls for more robust solutionswhen handling joint failure, and the industry demands mathematically robust approaches to handle even the worst case scenarios. For both serial and parallel manipulators torque failure is indeed a worst case scenario. Thus, a systematic analysis of the effects of external forces on manipulators with passive joints is presented. For serial manipulators we find under what conditionsthe robot is conditionally equilibrated, that is, equilibrated with respect to a specific externalforce. These conditions are, as expected, very restrictive. The serial, or subchain, case serves as agood platform for analyzing parallel manipulators. In parallel manipulators passive joints can appear as a design choice or as a result of torque failure. In both cases a good understanding of theeffects that passive joints have on the mobility and motion of the parallel manipulator is crucial.We first look at the effects that passive joints have on the mobility of the mechanism. Then, if themobility considering passive joints only is not zero we find a condition similar to the serial casefor which the parallel manipulator is conditionally equilibrated with respect to a specific externalforce.
