You could take a facility tour or do a video conference with someone holding a smartphone for a LOT less money.
There are excellent uses for telerobotic systems. This is not one of them. This is a solution looking for a problem.
You're missing the point, a person holding a smartphone controls what the viewer sees, a robotic system gives the viewer control of what they see which adds to the immersion.
