Unitree is doing everything Boston Dynamics is doing and more without a physical safety barrier between the robots and the humans.

Perhaps but but it doesn't matter. They have better production capabilities and more experience with drone swarms.

Yeah, that's the most impressive thing about this performance, the robots were safe enough to "interact" with children.

Even if we take into account the smaller size of the robots, it's still impressive, a bad input at the wrong time could easily cause of one of the robots to seriously injure someone, the fact this didn't happen and the producers and the company were confident that it wouldn't happen is the real breakthrough moment.
