Abstract

We present an experimental demonstration of smell-based molecular communication for mobile robots using gas sensing. Inspired by biological systems, information is encoded in chemical signals that propagate through the environment as volatile plumes and are detected by a gas-sensor-equipped receiver as transient responses. A robotic-compatible platform enables autonomous emission, detection, and interpretation of these signals. Representative sensor measurements exhibit distinct transient dynamics, enabling reliable detection of individual chemical pulses. The received signal shows clear attenuation with increasing transmitter–receiver distance and sensitivity to transmission pulse duration. The system demonstrates stable and reproducible communication behavior under varying spatial configurations. These results establish chemical sensing as a viable communication modality and provide a foundation for smell sensing-driven information exchange and coordination among autonomous robotic systems.
