The Movement Analysis and Research of 4R Multi-Joint Manipulator for the Loading and Unloading

This paper studies the problem of multi-joint robot with four degrees of freedom that is used in the process of loading and unloading, the method of homogeneous coordinate transformation is used to achieve the exchange between the implementation end of the space coordinate and the joint angle. Providing the theoretical reference and a basis of calculating for the follow-up study, and ultimately meeting the actual needs of production.
