In this study, firstly, serial robot manipulator which has 7-degree degree of freedom has designed by using Dynamixel servos and then kinematic analysis of this manipulator has performed. The inverse kinematics problem of the designed robot manipulator has been solved by heuristic algorithms developed with inspiration from nature and with a swarm intelligence and also these algoithms have been implemented in this designed robot manipulator by means of a GUI created with the MATLAB interface. In order to realize this process, the inverse kinematic problem was solved with a new IW technique called Random Decreasing Speed (RDV) which was used for the first time in this study together with the algorithm used on the basis of four swarm intelligence used in the literature. The RDW IW technique is a technique developed with inspiration from the movements of the golf ball and is used in conjunction with the PSO algorithm. In this context, this algorithm, firstly reinforced by the RDV IW technique, has been compared with the other four heuristic optimization algorithms in terms of position error and working time.
Since the calculation time obtained from heuristic optimization algorithms is far from feasible in a real robot, researchers have turned to FPGA technologies. Therefore, in this study, the inverse kinematics solution is realized with hardware based synthesizable PSO digital circuit design which has not been used in literature before.
As a result, software and hardware based performances of herd intelligence algorithms are compared in solving a complex problem based on robotics. The FPGA design, which can be synthesized, has been realized with the hardware description language known as VHDL, the results have been presented as simulation but also realized with Nexys 4 DDR card. All the software and hardware heuristic optimization algorithms used in this study were applied in redundant robot manipulator designed by MATLAB interface and the actual error values that occur at this stage due to the limitation of servo motors were analyzed and analyzed. |
