iSphere: Self-Luminous Spherical Drone Display
summary
A self-luminous spherical drone display named iSphere flies using a built-in quadcopter and eight rotating arcuate LED tapes that spin ~3 Hz to create a POV sphere; the prototype is 88 cm diameter, weighs ~4.5 kg (without batteries) with four motors producing >9 kg total thrust and shows about 144 × 136 resolution. Two adjunct yaw motors cancel reaction torque so the craft remains controllable; demos run ~40 flights but battery life is ~5 minute flight time, and noise and safety remain limitations.
