In a now viral video, a man controlling a Unitree robot accidentally made the humanoid kick him right in the groin, forcing him into a groaning heap while painfully and visually embodying the promise and perils of advanced robotics. Testing with humanoid robots is a very interesting new challenge. But be forewarned — despite all this razzle dazzle, many tech experts think humanoid robots aren’t quite ready for prime time use in the human environment due to various hardware and software issues. Judging from the pain the man took from the Unitree robot’s kick, though, these clankers may be better suited for the boxing ring than the factory floor, where they could be used for combat matches like in the movie Real Steel.
