His dog was frightened and trying to get away from it - that's why the guy kicked the bot. This has got to be one of the most stupid things ever. Imagine a crowded pavement, mums with pushchairs, people in wheelchairs or mobility scooters. How about 'blind' people who won't see the darn things coming at them - how will guide dogs react ? ! From what little I've seen on video - these bots seem to move quite fast too.
