(a) All joints move simultaneously resulting in contact at link 3 and leaving a gap between object and manipulator. (b) Only base joint moves until contact is made—the result is multiple points of contact at link 2 and link 3. Link 4 then moves inward until contact is made, resulting in wraparound.
