This week I worked on the Arduino feedback control algorithm, and tested robot arm with the Qr detection system. I changed the servo on the 4th axis to have higher volts and refresh at a lower rate, that helped with the jitter and keeping it reliably downward. I also centralized the Arduino, vacuum, motor controllers and horizontal actuator to 3d platform that we connected to a steel plate under the treadmill.
We are working to make our synchronous box pickup more reliable and quick.
