One immediate use I can see for this robot is racking and energizing circuit breakers in electrical switchgear, which is one of the most dangerous things an electrician does. Arc flashes are very bad for humans, robots can be replaced easily.

I'm not sure how robot will be better than a stick made of a non-conductive material. Stick is surely simpler and cheaper.

I’m not talking about using hot sticks used for disconnecting and reconnecting live conductors, I’m talking about removing and replacing switchgear breakers for maintenance and testing from energized switchgear.

There is a risk of arc flash when you disconnect the bus fingers and also when you reconnect them to the bus, and a robot is easier to replace than a human.
