This week I focused on final preparation and full system integration. We completed the hardware integration, bringing together the Raspberry Pi, camera, ultrasonic sensors, and robot base into a single working system. I worked on assembling the sensing components onto a breadboard and connecting them to the Raspberry Pi to ensure stable operation for the final demo setup. This required verifying wiring, signal reliability, and making sure all sensors could be read consistently within the control loop.
On the testing side, I conducted validation trials of the integrated system, focusing on key metrics such as following distance and maximum speed. I measured how well the robot maintains the target distance during motion and evaluated its responsiveness under different speeds. Based on these results, we further tuned the PID controller to improve reaction speed and reduce lag in following behavior. The system now responds more quickly to changes in user position while remaining stable.
My progress is on schedule, as these tasks align with our final integration and validation phase. Next week, I plan to continue refining the system and perform more comprehensive testing to ensure reliability and consistency before the final demo.
