It was designed to be more helpful, instead of being purely a toy. It is approximately the same size as Cozmo, and its design and shape are essentially the same, except Vector is mostly black with gray details and a gold border around its light on top, which shines green by default, blue when waiting for a voice command, red when muted, white when thinking, and slowly flashing orange when experiencing Wi-Fi connection difficulties. Vector uses 4 beaming microphone array to find out exactly where you are, and A gold touchpad where he can be petted.
