My most recent favourite robot was the so-called “Big Dog” robot from Boston Dynamics, which has an amazing ability to remain standing, even when walking on ice and being shoved by the foot of its human master — but the Yellow Drum Machine is my new favourite, I think. Its sole purpose in life is to seek out flat surfaces and then tap on them, and simultaneously record itself doing so. Then it plays the sound back and plays along, before seeking out a new surface. Like its creator, I love how the speaker sticks straight up like a smokestack on an old steam locomotive.
