Swarm - at night
Saturday, April 26, 2008
SWARM is a kinetic art work consisting of multiple semi-autonomous spherical robots (”Orbs”) that roll under their own power. Each has a spherical shell 30 inches in diameter: roughly waist high to an adult. Inside each Orb are batteries, motors to control speed and direction, as well as an audio system and color LED illumination, all under the command of a powerful on-board computer with wireless connectivity to other Orbs and a central computer called the Mother Node. Orbs roll without external wheels or actuators using the weight of the batteries as a ballast. Motors move the ballast off-center and cause the Orb to roll in that direction. Tilting the ballast away from the roll axis allows the Orb to steer.
