“…Very often, cable robots are designed to be redundant (i.e., with more active cables and hence motors, than degrees of freedom (dofs) of the moving platform, see for example, Reference [2]), however, fully actuated (i.e., with a number of active cables equal to the dofs, see for example, Reference [5]) and underactuated (i.e., with less active cables than dofs, see for example, Reference [6]) topologies have been studied too. Moreover, cable robots can exhibit a hybrid design (i.e., with both cables and rigid link mechanisms [3,7]).…”
