This here is a tiny biped robot that can ride a tiny bike around. It is adorable! Why does it exist, beyond to look adorable? I have no idea, but it does.
Why would a robot need to ride a bike when you could just build wheels right into it? Isn't the only reason that bikes make sense for people that we're weirdly-built meat sacks with bodies meant for running, not rolling? What good is this robot doing to anybody, anywhere? You know, I...awww, look! He thinks he's a little person! I just want to eat him up.
