Trajectory planning of a six axis serial robot based on dynamic analysis

Serial robots are by far the most common robots used in industrial applications such as welding, pick and place, and various processes. Computers and engineering programs play important role to constitute motion analysis and design process. These days, engineers can analyze all parameters to produce the generous robots which are required for the process and find effective solutions quickly by using computer programs with the development of the technology.In this study, a six axis serial robot is produced by using integrated approaches with parallel analysis in SolidWorks, CosmosMotion,VisualBasic, Abaqus and Adlink Motion Control Card. The parts of the robot are modeled in SolidWorks, rigidity is verified with finite element analysis in Abaqus and produced the real model of the robot. Kinematic analysis is studied in CosmosMotion by defining the velocity profile to the end effector point through the software algorithm developed in VisualBasic, which uses the application programming interface (API) capabilities. Different tasks are given to the robot in this study. The kinematic workspace and maximum motor velocities are evaluated by inverse kinematic analysis for each task. The kinetic workspace and maximum motor torques are evaluated by forward kinetic analysis. The rigidity workspace is evaluated by finite element analysis. The optimum trajectory is chosen after reviewing dynamic analysis and finite element results and the same trajectory is generated using ADLINK motion control card. Velocity mode is used. The maximum deviation for each motor is determined which is between the sending velocity profile data and the receiving feedback velocity profile data and compared whether the deviation values are in acceptable ranges.
