I used to work with an astronomical observatory which was located on a mountain (Mauna Kea). When things were running smoothly, the telescope could be controlled entirely remotely, and the observatory itself would be unoccupied. But often some little issue would arise that would require a button to be pushed, or would require some small display to be examined and a small manual adjustment made. Now by far most of the equipment could be reset or power-cycled or programmed remotely - but not everything. So occasionally someone would have to drive up and down a mountain just to push one or more buttons. If there had been a robot that we could control remotely and have it examine a display and push a few buttons, that would have been extremely helpful. If the robot had some onboard test equipment, like a spectrum analyzer, which it could plug into a test point and produce a plot for remote display, it could significantly reduce the grunt-work of technicians. I suspect there are a lot of remote sites for microwave towers etc which could really use a robot dog that could push buttons.
