Abstract :

     In the present research, an autonomous wheeled seven-degree-of-freedom robot with an adaptation mechanism to a passive diameter pipe was designed with the help of Adams software, and after checking the correctness of its movement, by designing a fuzzy controller in the Simulink section of the software, the dynamic simulation of its movement in various geometric conditions such as straight and vertical pipes, elbows, pipes with reducers, deposits and corrosion were investigated. A fuzzy controller was designed to guide this robot inside the tube, and its control system was implemented using direct current motors for each of the robot's wheels. The ability of the fuzzy controller of the robot to follow the desired input speed and its response characteristics in the steady state were investigated, and the presented results showed that the fuzzy controller performs better in following high speeds and has a better transient response at these speeds. Using the optimal torque distribution system, the robot control system is improved and the output signal of the fuzzy controller can be sent to the robot wheels in a targeted way. Therefore, the application of this method caused a significant reduction in the power consumption of the robot and optimization of its energy consumption. This designed robot has a high potential for making an accurate sample, commercialization and responding to the current needs of the country's oil and gas industry due to its less expensive mechanism compared to similar ones.
