1. A Cozmo robot, available at Amazon, and a USB wall charger.
2. An iOS or Android phone or tablet capable of running the free Cozmo app. Recommended: the Amazon Fire 7 for $49. But you can also use your phone, or an iPad.
3. A laptop or desktop computer running: 64 bit Windows 7, 8.1, or 10, or MacOS 10.10 or higher, or 64 bit Ubuntu Linux 16.04 or higher. At least 6GB of RAM is required.
4. Optional but recommended: An Xbox 360 or Xbox One game controller, available at Amazon in black or white. We recommend getting either the AmazonBasics controller or a genuine Microsoft controller for best performance. Other controllers may not work.
