• To enable indirect communication and coordination in uncontrolled environments.
• To validate the effectiveness of an artificial pheromone system.

Main Methods:

• Development of an artificial pheromone using magnetized ferrofluids.
• Implementation of stigmergy for location-based communication.
• Design of a detection methodology using low-cost magnetic sensors.
• Signal processing and parameter characterization of the ferrofluid signal.
• Experimentation with a heterogeneous swarm in uncontrolled environments.

Main Results:

• Successful indirect communication and cooperation between robots with differing sensor capabilities.
• Demonstrated robustness of the ferrofluid pheromone in various environmental conditions (e.g., wind, light, surfaces).
• Validation of the low-cost magnetic sensor detection system.

Conclusions:

• The proposed bioinspired artificial pheromone technology facilitates cooperation in heterogeneous robot swarms.
• Stigmergy-based communication using ferrofluids is effective for decentralized control in uncontrolled environments.
