Omnidirectional Mobile Grasping Robot Based on the VEX System

This paper proposes a cost-effective and highly flexible design for an intelligent omnidirectional mobile grasping robot based on the VEX system. The robot has three main components: an omnidirectional chassis, a roller suction cup, and a tracking wheel, enabling omnidirectional mobility, object grasping, and tracking functions. The structural design utilizes SolidWorks 2022 for three-dimensional simulation modeling and FDM 3D printing technology, effectively reducing manufacturing costs and improving design flexibility. The hardware system is based on VEX V5 series equipment, including a main control board, servo motors, infrared range-finders, visual sensors, and encoders. The software system adopts a PID control algorithm for precise motion control and object grasping. Experimental results demonstrate that the robot can effectively complete object grasping and transportation tasks, showing promising application prospects.
