You have a shiny, light-flashing robot that looks similar to EVA from Wall-E and designed to look friendly and nice. You better design the robot to safely handle kids coming up to it if you are putting it in a mall. The argument that kids should not be brought to malls is stupid. Who do you think malls target to bring money to them if not parents of kids, especially mothers of small children?
Good luck being the mall that says they don't care about child safety and keep away from our robots or we will run over you.
