The only real problem I can see when people are taking a picture is if they are getting in the way of the work going on, if the flash they are using is causing a problem, or if the person working on the robot is shy...
or... if they up to something sneaky.
Of course if todays society your photographed or videotaped a hundred times a day without anyone asking or in most cases you not even knowing.
I understand in the UK it even worst.
Big Brother is watching!
