This wee fellow wanders around until it finds something that looks like it can be used as a drum surface – a vase, a box, or whatever – and then rolls up to it and taps out a jaunty tune.
I wish this robot could be my dad. We’d have so much fun. We’d run through the world finding things to tap on. I’d say “Over there, dad!” and the robot would roll over and tap on a box or something and I’d say “I love you, dad.” and the robot would be quiet but I’d know what it meant.
