"ADB is a modular robot designed for tactile interactions with people. It is composed of a chain of prism-shaped robotic modules. Through the modules' coordinated behavior, the robot writhes, wriggles and twists in response to the presence of skin and force.
"The robot is animated only when actively engaged by a person, otherwise it is at rest. Stroking, rubbing or grasping ADB results in it pushing back, retreating or occasionally grasping onto a body part, depending on the combination of stimulus.
Inspiration for the project is drawn from Deep Blue, the computer that defeated former world champion Gary Kasparov in the now legendary 1997 chess match. This event marked a tipping point in the public imagination when the suggestion of a machine intelligence became tangible."
