ShapeBots: Shape-changing Swarm Robots
summary
A prototype swarm of 12 wheeled robots combines tiny tape‑measure style linear actuators that extend from 2 cm to 20 cm (0.1 mm polyester tape, two DC motors, 3D printed housing) with Wi‑Fi and camera‑based tracking on a transparent table; actuators deliver 0.3–1.6 N and robots use collision avoidance and a sketching UI to navigate. Demonstrations include physical bar graphs and text, a 30‑robot logo simulation, and ambient behaviors like desk sweeping and a temperature fence for hot cups, all working reliably in lab demos.
