We have those in Singapore as well, but you are not expected to tip.
(Tipping in a Japanese restaurant is weird anyway. People don't do that in Japan, and they don't do it in any of the authentic Japanese places I've been to.)
IPad ordering is fairly common here. I like it, very efficient.
There's a sushi place around here that does iPad ordering, but they deliver your food on the customary conveyor belt, not via robot.
