A wide variety of technologies and methods make Hanson robots the world’s most lifelike. As Hanson integrates disciplines including mechanical engineering, material science, computer animation, and artificial intelligence, a new super-disciplines emerges, leading towards a gestalt of sentient personalities both as art and artificial organisms.

The life in our robots springs from innovations including: Character Engine cognitive AI software, our bio-inspired nanotech known as FrubberTM, bioengineered facial mechanisms,  walking biped robot bodies with grasping hands, & a great deal of artistry too.

The Character Engine A.I. software adds the spark of soul—enabling our robots to think, feel, to build relationships with people as they understand your speech, see your face, hold natural conversations, and evolve. As we proceed, we expect our robots to grow ever smarter, building increasingly meaningful relationships with people.

And all our software is open source:,, and

The software controls our android hardware, including expressive faces on walking biped robot bodies. Hanson’s patented Frubber (“flesh rubber”), a spongy elastomer using lipid-bilayer nanotech, self-assembles into humanlike cellwalls (inspired by human cellular mechanisms). As a result, Frubber mimics human flesh more accurately than any other known technology, using 1/20th the power of other materials to achieve hyper-expressive robot faces. These innovations enable a greater range of expressions, with better aesthetics, and moreover lightens the mechanism and power-consumption, to enable the world’s first total walking androids.

Thanks to the Frubber, we can pack more expressions in our robots. Our robot mechanisms mimic the action of over 64 muscles in the human face, eyes and neck, with the size and speed of action comparable to natural human facial actions. Under the control of the Character Engine, these faces become a new animation medium–one that befriends you.

And the artistry is essential to bringing robots to life. Frubber, Character Engine, walking robot bodies–all serve as media for creative interpretation in the hands of our artists, explored artistically for surprising effects. David Hanson’s background as a Disney sculptor, and RISD film-maker, redefines robots as four-dimensional interactive sculpture. This approach transmutes technology into a living being, to achieve a character via integrative fusion of the mechanisms, materials, and responses of the  intelligent software, to choose any of billions of possible expressions, affected at just the right moment–the robot simply comes to life, looks you warmly in the eye, and inspires the sense of a mind within the machine.
