The most significant risk remains the integration between motor mobility and the vision pipeline, especially the coordination between target tracking and obstacle detection, and while we have made some progress by starting ultrasonic sensor integration, the system has not yet been tested as a whole in real scenarios. Another important risk is that most of our testing so far has been done in software through unit tests, with very limited testing on actual hardware, which means there may be unexpected issues when the robot operates in real environments. To manage these risks, we will start hardware testing as early as possible even before full integration is complete. As a contingency plan, if the full system does not perform reliably, we will simplify the behavior so that the robot prioritizes safe stopping instead of complex navigation.
There are no major new design changes this week, but we continued implementing the previous change where the robot automatically moves around obstacles instead of requiring user input, and we also started integrating ultrasonic sensors to improve obstacle detection. This change was necessary to improve the usability and safety of the system based on feedback, but it introduces additional integration effort and requires more time for tuning the interaction between sensors and control logic.
There are no major changes to the overall schedule at this point, as we still expect integration to be completed in less than one week and testing to take around two to two and a half weeks. However, we plan to start hardware testing earlier than originally planned as soon as partial integration is ready, which allows us to identify issues sooner while keeping the overall timeline unchanged.
