The work we completed this week can be discussed in following sections:
- Camera Integration and Algorithm Development:
- We have integrated a new Stereo Camera module (NVIDIA JETSON NANO/XAVIER NX, DUAL OV2311 Monochrome Camera Module) into our system. Initial tests with the YOLO model showed a decrease in detection accuracy; hence, we are currently retraining the model to adapt to the new camera’s specifications.
- Our work on the software app saw considerable advancement with the successful integration of the iPhone API, allowing real-time display of device information such as phone temperature and charging status.
- Hardware and Mechanical Design:
- Due to a delay in receiving aluminum profiles and motor accessories, our plans to assemble the gantry system were postponed. Instead, we focused on refining the CAD models and simulating motor placements.
- The motor support structures were fabricated using a 3D printer at the Roboclub. However, issues with the slicing process led to insufficient hardness, necessitating further printing next week.
- Electrical and Control Systems:
- Wiring the Jetson Orin Nano proved challenging due to the increased number of peripherals, but we successfully assigned the motor driver to available analog pins. The setup was verified using a logic analyzer.
- We are preparing for the arrival of the hardware this Friday, with plans to connect and debug the motor controllers and start constructing the gantry system.
- Documentation and Compliance: we carefully went through the comments in our design report because it seems that there are problems both quantitatively and qualitatively. For example, the use case requirements part do need to include some quantitative information. However, due to lack of detailed information, we missed some important information for several parts. Therefore, we are working on the report to refine the content. We believe we will continue to work on it next week to include more details regarding our design.
Next week, our team will focus on enhancing the YOLO model’s detection accuracy through continued retraining and testing. We’ll also conduct further tests on the updated user interface to ensure accurate data display for all phone models. Once we receive all necessary parts, we’ll begin assembling the gantry system and cutting the rails. Additionally, we’ll work on refining our design review report to address any remaining issues.
