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
In this new video, I explain how I designed my four-legged PCB Robot MKIII, having a BLE module and a simple circuit for driving the coils and charging them!
MKII test video!
Now that I have proofed that the idea can work out, I can start designing MKIII.
PCB Robot MKIII will be made from just a pcb, magnets and a battery. This cheap robot will be ideal for swarm robotics.
My new light-weight design:
3 freakin' grams! (Yes I'm going to have a problem with the battery for MKIII but I have a plan)
This was my first attempt in trying to use flexible PCBs as robot legs!
As shown in the video this prototype manged to make some small steps but I was expecting a better behavior. These are all the things that needs to be improved for MKII:
