It is an evolution of the existing design, boosting the in-robot cameras to a twin HD-video solution, an upgraded Atom 1.6GHz CPU, a better walking algorithm to provide better control of its servo's torque so the robots movements are more fluid and powerful, and a few other improvements. Most importantly, they have added in voice recognition from Nuance--from the same technology behind Apple's Siri. This will add a whole new dimension into the future of household robots, in which you will be able to give him commands such as: "Robot, answer the doorbell please". It is an exiting piece of technology.
