Dauto-san is a top humanoid robot builder that consistently captures high standings in Robo-Fight, ROBO-ONE, and other Japanese competitive robot competitions. He is also the absolute best, in our personal opinion, at the challenging game of Robot Billiards.
He's not afraid to try some new approach with his robot designs. Some of them work, others don't, but he keeps trying and constantly improving. His latest design, which you can see in operation in the video below, initially made us chuckle. No, that's not quite right. We almost doubled over laughing.
Yet, when the initial laughter stopped, and we had a minute or two to digest what he had done with the robots lower half, we were totally amazed. It's a really unconventional approach the provides greater stability and more DOF. And, surprisingly enough, it seems to fit within the basic humanod robot competition specifications. Brilliant, absolutely, brilliant.
