It was a long 10 hours; I moved back and forth between different parts of the project. I installed the self-locking nuts onto the motor shafts (a very long, arduous, and boring process). Afterward, I built the entire conveyor system, but while i was working on it- and during a test run of the rover by my teammate-the brushless motor drivers burned out. We managed to get almost everything working in time to shoot the presentation video for the WRO. I assembled the entire scanner, mounted all the internal boards, and did a great job with the wiring. In meantime, I received a Centaury Carbon 2 Combo, a gift from our sponsor, Crea 3D.
