P3.31 Extenders are robot manipulators that extend

(that is, increase) the strength of the human arm inrobot manipulator applied to the load. Determine a state variable model and the state transition matrix for the system.

Load load-maneuvering tasks (Figure P3.31) [19, 22]. The system is represented by the transfer function Y(s) G(s) = U(s) 30 $2+4s +37 where U(s) is the force of the human hand applied to the robot manipulator, and Y(s) is the force of the Extender Gripper FIGURE P3.31 Extender for increasing the strength of the human arm in load maneuvering tasks.
