If you’re familiar with the Anki Cozmo robot, you already have a sense of what Vector looks like. Standing around three inches high, it’s small enough to fit in the palm of your hand. It has little treads for motoring around a small space, but you’ll probably want to make that space a table or desk instead of your floor so you don’t step on it. It has a little lift arm that’s only able to pick up a tiny plastic cube.
Vector’s main activity is tootling around on a table and investigating its surroundings. Using a combination of sensors, it builds a little map of its surroundings. If it detects a new object, it’ll go check it out and see if it can be pushed around. It pays attention to sound and is able to recognize faces. It’s more self-sufficient than the Cozmo robot; it’s able to find its charger on its own.
Anki has essentially put the guts of a midrange smartphone inside Anki, allowing it to work without tethering to your phone. It has a camera and uses machine learning to recognize people (and, eventually, objects). It can hear what direction sound is coming from, thanks to beamforming microphones. It has cliff sensors on all four corners to keep it from driving off the table.
