Inspired by puffer fish, cartilaginous sharks, and armadillo penises, all of which show exhibit remarkable stress/strain curves versus hard materials. The inventor Saul Griffith (with beard) shows it off to a gaggle of Googlers. Each arm weighs only 1 pound and so it moves and changes direction at remarkable speeds (our minds presume something that big would have more inertia). But the high-speed control algorithms are not perfected yet. I was sitting next to Rodney Brooks, and had to suggest that they are “fast, cheap and out of control.” His robots are sewn. They deflate to a pile of fabric. No gears. No rigid structures inside. (Name suggestion from audience: "Sewbots") With four people on a walking robot, “it has a strength-to-weight ratio 10-100x better than hard robots.” A key insight from nature: “compliance can substitute for mass” Trees survive a storm better than telephone poles. Now working on soft wrap-around prosthesis for arm and leg. Others: “We now know that the heart is a linear sheet of muscle wrapped in a knot.” He also showed a design sketch of a muscular-looking submarine. Then, add fluidic computation and <a href="https://www.flickr.com/photos/jurvetson/6921980487/#comment72157629069372392">soft sensors</a>… “We have SolidWorks, but there is no CAD tool yet for SoftWorks.” Otherlab: “we have too much fun.” Why do this? “To delight my 6-year old niece who asked me if she could ride a <a href="http://www.hizook.com/blog/2011/11/21/inflatable-robots-otherlab-walking-robot-named-ant-roach-and-complete-arm-plus-hand" rel="nofollow">toy elephant</a> to school, we should do this.” Here is a <a href="https://www.youtube.com/watch?v=eWIwRR5a8s4&feature=youtu.be" rel="nofollow">short video I took of it in action</a>. It gives a good handshake. |
