How to Build a Quadruped Robot - NO MATH! -- Episode 538

A great robot. The design of the legs looks interesting. I might have to have a closer look to see if there are any ideas I can borrow. I have had a number of goes at designing my own 3D printed walking robot, see photograph. I didn't get very far as I was still struggling with the 3D printer at the time, plus I wanted to minimise the number of servos - in my case to only 8. I've since given up on trying to minimise servos and use as many as I like with a PCA9685 16 channel PWM pcb (which works well) with a biped robot I am playing with. 

I did work out that if the four legged robot was square rather than oblong, then it is just about possible to balance of three legs freeing up the remaining leg to be moved forward. In this way the robot is able to 'walk' without having to ground the base. I did not quite manage to get it going as it all depended on where the centre of gravity is and I had not yet placed the batteries. I might have to return to it some time to see if I can do better.

well my design was based on ...nothing really I just winged it. A square overall shape would have been easier to work with in hinsight. the robot now tends to fall bawards on long steps.
If I d do another one I'd put more time into the mechanical design from a theoretical base.
