This kit gives kids a simple, fun, and customizable introduction to robotics. Choose between the four-wheeled rover or the two-wheeled robot Sidekick, and get programming! Transform your Sidekick into its other mode any time you want. As soon as your Sidekick is assembled, you can begin programming its movements directly on a built-in keypad. You can also download the free Sidekick app (Android or iOS) to unlock all of the Sidekick’s capabilities.
