Accomplishments: This week, I addressed two crucial issues in the circuit design. First, I fixed the problem where the circuit would sometimes stop looping when the sensor went out of its working range by setting the board to reset every 5 seconds, ensuring that the loop never stalls for more than 5 seconds. Second, I resolved interference between sensors when one was pressed by implementing P-MOSFETs to make each sensor’s power source independent, preventing cross-voltage interference.
Progress: Fixing these two issues was faster than anticipated, which has significantly advanced the project. Additionally, I built a first draft of a more compact version of the circuit to fit neatly on the controller, transitioning from a breadboard setup. I am on track to complete this streamlined circuit by Sunday.
Next Steps: Next week, the team will gather to integrate all individual systems, so I’ll ensure my system is fully complete and ready for integration. I will finish assembling and testing the compact circuit on the controller, verifying its stability, and assisting my teammate in implementing the force sensor setup on the robotic arm to facilitate a smooth integration process.
