The weed laser system was integrated onto a goBilda Recon mobile robot chassis, providing a robust foundation for autonomous operation. A custom-designed, 3D-printed PLA frame was fabricated to ensure structural integrity and stability during operation. An adjustable two-degree-of-freedom (DoF) robotic arm, responsible for manipulating the laser, was incorporated into the chassis assembly (Figure 2a, b). The laser and camera were co-mounted on a shared bracket, maintaining a fixed relative position and orientation to facilitate precise synchronization during weed detection and removal processes (Figure 2c).
