Here is a new image, you will notice the addition of 2 new joints in the legs.
This will be changing once again as the hip joints will get changed from twist to lean.
Also the feet have changed to look like shoes and have a little more weight/stability to them.

Evidently, the Robot has a fondness for M&Ms. With adaptable limbs and shoes, it could be an interchangeable enterprise. Skiis, skates and perhaps even Crocs for downtime moments. :bananamouse:

Looking good!

Oddly enough I actually designed some skates, will take like 12 hours each to print but once he is up and walking the way I want will be trying this.

Okay so here is the new and improved robot that has the hip joints changed to lean. I also redesigned the main body/chest so that the servos for the hips would be inside the body and not attached on the outside. This reduced the total height by about 10mm which is great as it give it more stability. The walk cycle does well but after some testing have found that the Thigh and knee pivot brackets need to be extended by about 5mm to give the leg more freedom and a faster walking gait.

He/She looks awesome!
I would hide the exposed wires.

Thank you Steinie.
Wires will be hidden to some degree. This is just a proof of concept/ prototype for the larger one that will be done.
Did redesign the pivot brackets and found that 5mm was not enough had to go with 10 but only the thigh brackets needed changed.
The walk cycle is better but still not exactly what I want, just not smooth enough yet. Walks well on a smooth surface but carpet is hit or miss.
Will post a new picture soon.
