Hardware
The Huggable™ is a sophisticated robot featuring a full body sensitive skin with over 1500 sensors, quiet back-drivable actuators, video cameras in the eyes, microphones in the ears, an inertial measurement unit, a speaker, and an embedded PC with 802.11g wireless networking. An important design goal of the Huggable™ is to make the technology invisible to the user. You should not think of the Huggable™ as a robot but rather as a richly interactive teddy bear. The actuators are designed to be silent and back drivable so as the Huggable™ moves, you do not hear or feel gears. The movements, gestures and expressions of the bear convey a personality-rich character, not a robotic artifact. A soft silicone-based skin covers the entire bear to give it a more lifelike feel and heft, so you do not feel the technology underneath. Holding the Huggable™ feels more like holding a puppy, rather than a pillow-like plush doll.
