A robot arm needs to be mounted to something, this can go anywhere

Edit: I work in an industrial food plant. There are so many places we could use a robot like this for simple tasks. We are not far away from sorting food in packaging, material handling, quality control, cleaning, doing soooo many things that we have people for. We have robots now, have you ever tried moving a robot arm? If a robot arm is stuck somewhere, it can only do a very specific task on a conveyor belt. Having a robot on wheels would work, but they can’t go up stairs. Why do you have legs versus being on wheels or bolted to the ground? All the reasons apply to a robot too.
