It can not only work in an environment where people can't work, but also can maintain long hours of the work, with the low failure rate. With the rapid development of the robotic arm research technology, the robotic arm has been widely used in aerospace, medicine, industrial production, anti-terrorism, and explosion and service industries. Due to the strict quality restriction, the rigidity of the robotic arm is low, and there are geometric errors and flexible deformation errors. In order to improve its performances, it is necessary to reduce the end positioning error of the robotic arm by means of the restructuring technology.展开更多
