I always like when people make tutorials that walk their readers through step by step from start to finish. Last year I found an amazing post from a guy who wanted to teach his daughter a little about robotics and share his journey on his blog. The tutorial talks about 3D printing a chassis for the robot, designing and fabricating his own PCB board and the trial and errors he faced while designing this small robot. Its a nice read and has good insight to designing and building your own robot from scratch.
Thank you design & make for a great tutorial.
