“…Control engineers have been working on the development of a mathematical model and the control of flexible structures. Flexible mechanisms and flexible-joint manipulators were applied for reducing the vibration in the remote manipulator system in a space station-assembly shuttle flight [1], performing decontamination tasks in nuclear maintenance and positioning the nozzle dam in the maintenance of a nuclear power plant's steam generator [2], remediating a waste storage tank [3], cleaning a waste tank [4], operating in microsurgical applications [5], positioning a patient system for cancer patient treatment [6], deburring [7], surface polishing [8], and grinding, painting, and drawing applications and biped-walking and walking machines [9]. They are mostly used in the service, space, medical, and defense industries.…”
