I mean, yeah. I Did A Thing did a video on exactly this a year or so back. His setup was a complete shitshow as they had to change robo-dogs at the last second (because Michael Reeves and OfflineTV didn’t want to get sued by Boston Dynamics) but the principle was sound.
But also? You are never going to replace a well trained soldier with this. Even with a proper gimbal mount, you aren’t doing rapid precise shots.
But also… you don’t need to. The advantage to this is to have a relatively low cost platform to handle suppressive fire or fire an anti-tank shot or whatever. Something where you would otherwise be risking a human being.
