The new PCBs have just arrived! Thank you PCBway for sponsoring this project!

The flexible PCB is going to act as both the brain and the muscle of my PCB Robot

The rigid FR4 PCB is the frame that's going to prevent the middle part (were the electronics is going to be soldered) from bending and also hold the 4 magnets. Hats off to PCBway for pulling this off! The pcb is 0.6mm thick and it's width is just 1mm! So the milling machine had a very difficult task but they still managed to do it :D
