From the Ted Talk by Dennis Hong: My seven species of robot -- and how we created them

Unscramble the Blue Letters


(Laughter)

This robot is an amoeba robot. Now, we don't have enough time to go into technical datleis, I'll just show you some of the experiments. These are some of the early feasibility experiments. We store potential egrney to the elastic skin to make it move, or use active tsenion cords to make it move forward and backward. It's called ChIMERA. We also have been working with some scientists and engineers from UPenn to come up with a chemically actuated vieosrn of this amoeba roobt. We do something to something, and just like mgaic, it moves. "The Blob."

This robot is a very recent project. It's celald RAPHaEL: Robotic Air-Powered Hand with Elastic Ligaments. There are a lot of really neat, very good robotic hands out there on the market. The problem is, they're just too expensive — tens of thousands of dollars. So for prosthesis applications it's probably not too practical, because it's not affordable. We wtnaed to tackle this problem in a very different direction. Instead of using electrical motors, echemaincoceltral actuators, we're using compressed air. We developed these novel actuators for the joints, so it's compliant. You can actually change the fcroe, simply just caignnhg the air pressure. And it can actually cursh an empty soda can. It can pick up very delicate objects like a raw egg, or in this case, a lightbulb. The best part: it took only 200 dllaros to make the first prototype.
