Compared with a traditional industrial robot of equivalent functions (such as Cartesian coordinate robot and industrial serial robot), a parallel robot has the advantages of simpler structure and higher acceleration and deceleration capability. In addition, serial robots have some problems such as singularity, which can be solved by increasing redundancy constraints or adding redundant drive. Parallel robot is currently receiving a great deal of attention in industry and academic circles

GPM series of redundant parallel robots is a new experiment and research system specially designed and developed by Googol Technology for research of redundant parallel robot. GPM can be used in robotics courses such as automation control and mechatronics to support laboratory experiment requirements in robot mechanism, kinematics, dynamics, motion planning and programming. This system can also be used in research of controlling and programming of redundant parallel robot, as well as a non-linear system with three inputs and two outputs, to research various nonlinear control algorithms and redundancy coordination control algorithms, assisting the control experiments of various automatic control theories. Besides teaching and research GPM series of parallel robots can also be used in developing new principles and experiment prototypes of high-speed, high-accuracy gluing and bonding machines.
