Robotic wonderment

I met up with 4 year old grandson and his Auntie who had been experiencing some culture earlier. We had just left a well known toy shop when we encountered this robot . It looks a bit like RT 2D or whatever it is from Starwars.
Anyway Alfie had great fun with him and nearly jumped a mile with shock because the robot moved off as he tried to tilt him to see how he worked! Alfie was oblivious to the 'controller' in the doorway of the shop.
