A robot that can play "Rock, Paper, Scissors," do calculations, function as a compass or digital dice, measure temperature, and be controlled via an app – that’s Proxi. The assembly of Proxi is part of the experiment kit, and the instructions provide a step-by-step guide on what to do and tips on what to pay attention to during assembly. This promotes fine motor skills and offers a great insight into the inner workings of the robot. In this way, children can easily understand how Proxi operates. Once Proxi is assembled, the micro:bit board comes into play. KOSMOS offers ready-made codes for download for programming beginners, so they can start playing with Proxi right away. Children simply need to connect the micro:bit to a computer using the included USB cable and drag and drop the downloaded code onto the board. Then, the micro:bit is inserted into Proxi's head, and the fun can begin: it sings and dances, becomes a bowling ball, or displays little notes on its screen. Of course, children can also program the micro:bit board themselves. The instructions explain how to do this in a child-friendly manner with a clear example. The micro:bit board is programmed using a graphical, block-based programming language (MakeCode). Children can modify existing codes or write their own programs. And naturally, they have access to all the knowledge and projects of the vast micro:bit community. Proxi is an officially recognized micro:bit accessory kit by the Microbit Foundation.
