it is a real threat

Very cool, but video looks accelerated and something about the robot shading/lighting gives it a rendered feel.

The video looks fake or at least enhanced. A net or a bucket of oily sand would disable that annoyance.

That video clearly states that they have always placed great emphasis on product safety and information security, and that they kindly request that all users refrain from making dangerous modifications or using the robot in a hazardous manner.
