Building a Robot so I don't get kicked out of Uni

A student engineer documents building a biped wheeled-balancing robot as a university thesis project. The build covers 3D modeling and printing the robot body using PLA Pro and TPU, PCB design with KiCad, CAN bus wiring and debugging (including a 14-hour troubleshooting session caused by internal termination resistors), and implementing a cascade PID controller for balancing. The inner PID runs at 100 Hz controlling body angle, while the outer PID at 10 Hz controls speed. The robot eventually achieves basic balancing and remote-controlled movement.
