Could a robot short-circuit and electrocute you if it were touching you? Could it blow up and you too if you were too close? Are robots safe to be around?

Robots would be operated on a voltage source lower than the lethal limit. They could not blow up unless there is an explosive device inside of them.

I worry that something electronic or electric will blow up. I have no idea why. I mean do TV's ever blow up or computers? The only violent thing I've ever experienced was many  years ago.  There were a loud BOOM in the kitchen when I was a kid and we all went running in to see what happened. My mom was making something in a pressure cooker and the release nozzle got stuck! We  had pieces of chicken and tomato sauce everywhere  from floor to ceiling! Fortunately no one was in the kitchen at the time. I think it traumatized  me. I have never owned a pressure cooker. Once was enough. Do you have a pressure perchance? Thank you for your reply Ele. Could a lightning strike  cause something to explode?
