DIY robot can mimic and replicate your actions in just 40 hours
Have you ever thought about cloning yourself? Just imagine how much work you could get done, how many chores and household tasks you could complete, if only you had a team of clones that could reproduce your actions. While cloning technology isn’t there yet, you might be able to accomplish the same feat with robots. Now, I know what you’re thinking. “I’m not a roboticist. I don’t have the skills to program a robot to replicate my every move.” Turns out, you might not have to. Researchers have engineered a robot that, once shown a desired movement, will mimic and learn how to perform the action itself. It’s equal parts ingenious and creepy.
A team of researchers at Stanford University have engineered and constructed the HumanPlus robot, which is designed to shadow the movements of humans. The team, which consists of Zipeng Fu, Qingqing Zhao, Qi Wu, Gordon Wetzstein, and Chelsea Finn, documented their journey in a recently published paper titled “HumanPlus: Humanoid Shadowing and Imitation from Humans.”
According to the team, they used 40-hour human motion datasets to teach the robot how to perform an array of activities that includes playing ping pong, boxing, typing on a keyboard, playing the piano, and more.
In an excerpt from the paper, the team writes: “This policy transfers to the real world and allows humanoid robots to follow human body and hand motion in real time using only a RGB camera, i.e. shadowing. Through shadowing, human operators can teleoperate humanoids to collect whole-body data for learning different tasks in the real world.”
But the HumanPlus robot does more than just mimic human movements. It can actually learn the movements. According to the team, “Using the data collected, we then perform supervised behavior cloning to train skill policies using egocentric vision, allowing humanoids to complete different tasks autonomously by imitating human skills. We demonstrate the system on our customized 33-DoF 180cm humanoid, autonomously completing tasks such as wearing a shoe to stand up and walk, unloading objects from warehouse racks, folding a sweatshirt, rearranging objects, typing, and greeting another robot with 60-100% success rates using up to 40 demonstrations.”
In a recent Inverse article, author Jackson Chen wrote: “The HumanPlus’ design is open source, so nothing is stopping you from adjusting the it as you see fit, so long as you have the technical know-how to do so. One of the researchers, Zipeng Fu, noted that the hardware required to remote control the HumanPlus only costs $50, which is much cheaper compared to the more popular option of using a Meta Quest headset.”
