Stuffie Mobile is a robotic platform for plush toys conceived through a co-design process with children aged 5-10. It is designed to allow a plush toy to be attached on top to give the toy the ability to move during play. The platform consists of two rear wheels driven by motors and a single omnidirectional front wheel. By controlling the direction of the motors' rotation, the platform is capable going forward, backward, and turning. To control the platform, children use a web application to program its movement. This gives them a chance to experience a basic form of programming at an early age in a casual and fun environment.
