Tribble: The Robotic Interactive Ball-Based Living Entity


The Tribble project demonstrates the application of dense, distributed sensor networks to electronic skins. The Tribble is a one-foot diameter sphere tiled by a 32-node systolic sensor network, with each node capable of multi-modal sensing (pressure, light, sound, temperature) and actuation (glowing, purring). There is no central controller�all behavior evolves from communication between proximate patches of electronic skin. Current research on this platform is exploring algorithms for distributed sensor calibration.
