DragonBot is a new robot platform from the Personal Robots Group at the MIT Media Lab. Specifically designed to support long-term learning interactions between children and robots, this video introduces Kombusto, the first DragonBot. The robot runs entirely on an Android cell phone, which displays an animated virtual face. Additionally, the phone provides sensory input (camera and microphone) and fully controls the actuation of the robot (motors and speakers). Most importantly, the phone always has an Internet connection, so a robot can harness cloud-computing paradigms to learn from the collective interactions of multiple robots. To support long-term interactions, DragonBot is a "blended-reality" character–if you remove the phone from the robot, a virtual avatar appears on the screen and the user can still interact with the virtual character on the go. Costing less than $1,000, DragonBot was made to be a low-cost platform that can support longitudinal studies of human-robot interactions "in the wild".
