Like comedy, humanoid bipedalism is hard. I guess no one really ponders why most actual humans spend the first two years of their lives falling on their asses and then after a lifetime of bipedal mobility, at the end of our journey return to being one-years-old and falling on our asses again. The video above is from a Russian presentation promoting this new Humanoid robot. It didn’t go as planned. Having spent over a decade playing with little robots, of the LEGO variety, actual bipedal locomotion isn’t even attempted and I just put some wheels or treads on the thing and call it a day.
My 8th Graders attempted to build a bipedal “dinosaur” robot. A different group of 8th grades attempted to build a four-legged robot, but I guess I didn’t record any videos. I understand the attraction to having humanoid bipedal robots, but it’s so much more complicated than most can even imagine. These kids work really hard to get their robots to work.
Here’s what DARPA challenge robots were capable of ten years ago (they’ve since learned how to dance and do parkour). Enjoy.
