Ozobot

There’s no assembly required here, but that’s because the creators of the Ozobot have managed to cram a surprising amount of capabilities into a tiny rolling robot smaller than a golf ball. That means it can roam and autonomously navigate your desk using proximity and optical sensors, or do the same thing on that minuscule seat tray you’re forced to work and eat on during a flight. Despite its size, the $175 Ozobot includes LED lights, a speaker, a battery that’s good for about 60 minutes of play, and Bluetooth (allowing it to be connected to and programmed using an app on a mobile device).
