Abstract:The mechanical structure of the robot was designed according to the design requirements, and the solid model was built using SolidWorks, then the systematic dynamics simulation model was built in ADAMS,on the basis of the robot's actual geometrical parameters, physical characteristics and constraint conditions. Through the simulation of space trajectory tracking in the position of maximum load of the robot, the rationality of the design is proved and it provides valuable information for the follow-up research work of optimizing the robot structure and enhancing the control quality.
