As Cooper Perkins had worked on the development of robots at the MIT Media Lab, its renowned roboticist Dr. Cynthia Breazeal asked the Cooper Perkins to build a prototype social robot that has now evolved to the Jibo. The dynamic architecture of this social robot is based on rotatable, canted platforms representing body elements to express emotive responses with users. The challenge was to convert precise positions, velocities, and accelerations of the moving components first modeled on computer animations to a physical model design without off-center instability. The device is powered by a mobile phone, has many sensors to assess its environment, and communicates in an engaging manner with uses.
