It looks like a cheap, Chinese-made GO-1 robot with an RPG-26 LAW mounted on its back. The robot is useless in rough terrain or bad weather (made for household use) and because the RPG-26 has to be manually cocked by flipping up the rear sight (no idea why the front sight is flipped up in the video, except to look scarier), it has to run around fully armed and ready to fire all the time, creating a potential danger to even friendly forces. Max payload for the GO-1 Pro version is 3kg, which the mounted RPG-26 with missile would exceed at 3.5kg, so obviously (or at least hopefully!) the weapon in the video is empty. And because of the weight limit, the addition of a fire control system or trigger-pulling mechanism would add even more weight.

That is a large part of why Russia is losing in Ukraine. Their military budget mostly goes to someone's nephew, who just steals it.
Thank god for Russian thievery!
