This project focuses on creating a logistic vehicle equipped with a mechanical arm designed to retrieve items from shelves in a specified order and place them in designated locations. We have employed omnidirectional Mecanum wheels for the chassis and interconnected servos for the robotic arm.

Running Rules

Design and construct an autonomous intelligent robot tasked with material handling according to predefined missions. The robot should be capable of receiving transport tasks via methods such as scanning QR codes or communication through a Wi-Fi network. Within specified industrial settings, the robot should navigate and avoid obstacles, transporting materials to designated locations with precision.

The operation begins with placing the robot at a specified starting point and initiating it with a uniform command. Timing commences at this point. Within a predetermined time frame, the robot moves to a QR code display board, scans the QR code, and retrieves the sequence for transporting three different colored materials. Subsequently, the robot moves to the raw materials area and transports the upper-layer materials in the order specified by the task to the corresponding color zones within the rough processing area.

Once the three materials are transported to the rough processing area, the robot arranges them in the respective color zones within the semi-finished product area, following the sequence from the upper-layer raw materials area to the rough processing area. After successfully moving the three materials from the rough processing area to the semi-finished product area, the robot returns to the raw materials area. It then proceeds to transport the lower-layer materials in the specified order to the corresponding color zones within the rough processing area, following the sequence from the lower-layer raw materials area to the rough processing area. Subsequently, it transports the materials from the rough processing area to the semi-finished product area, where these three materials can be placed flat or stacked on top of the existing materials (matching in color). The scoring for both flat placement and stacking is evaluated based on the visibility of the outer ring of each color ring when viewed vertically from the outside. The weighting of scores differs between the two methods. Throughout the handling process, the robot should load materials onto itself, with a maximum of three items per load. Upon completing the task, the robot returns to the designated return area.
