Devlog #2: Today focused on advancing both the software and mechanical portions of the autonomous trash collection drone. On the software side, the LiDAR subsystem was completed. The Python script for the RPLIDAR C1 was finalized, including initialization, communication with the sensor, and collection of scan data. The script now reads distance measurements and angles from the LiDAR, providing the foundation for future obstacle detection and avoidance logic. Time was also spent organizing the software architecture and researching the required Python libraries for each subsystem of the drone. The project dependencies were separated into categories for computer vision, sensor processing, flight control, and networking, and virtual development environments were configured and tested to prepare for future development. On the mechanical side, significant progress was made on the robotic gripper assembly. Most of the CAD modeling for the gripper arm was completed, including the overall geometry, servo mounting, gear layout, and finger mechanism. Existing component dimensions were reviewed to ensure compatibility with the DS3218 servo, bearings, and planned fasteners. The gripper design is now largely complete and serves as the primary end effector for the drone’s trash collection system. Overall, today’s work established a solid foundation for both the software and hardware systems. The LiDAR subsystem is now operational at the software level, the project’s development environments are organized for continued programming, and the gripper assembly has reached an advanced stage of mechanical design. These milestones prepare the project for integration of obstacle avoidance, object detection, and physical manipulation in future development sessions.
