It’s a little known fact that Isaac Asimov’s Three Laws of Robotics is missing a law: The robot shall be able to do Tai Chi. Thankfully, there’s the Hovis Eco, a tiny, plastic-clad humanoid robot by Dongbu Robot.
The robots cost $ 900 for the plastic clad version (the Eco) and $ 730 for the more barebones model below. They are programmable and can move and dance at your command. You can check them out here.
You can upgrade your wee fellows with servos, a new head unit, and optional sensors. The Eco weighs about four pounds and is 16 inches tall. Almost a thousand smackers is a little much for a little robot that can do martial arts moves, but who knows – maybe you can teach it to bring you a beer or something.
