Grigore Vasiliu

About

Grigore Vasiliu is a robotics researcher whose work centers on real-time obstacle avoidance, embedded fuzzy control, and bio-inspired swarm intelligence for autonomous mobile robots. His most influential contribution is the **Rebound Algorithm**, a simple, reactive obstacle avoidance method designed for low-cost sonar or infrared sensors and fast enough to run on embedded microcontrollers. This work, published in 2009, has garnered 20 citations and remains a practical reference for resource-constrained robotics. Vasiliu also advanced fuzzy logic control by implementing real-time, embedded controllers for wheeled mobile robots like the Pioneer 3-DX, achieving simultaneous speed and steering control—a contribution cited over 25 times across related papers. A particularly innovative thread in his research is the use of **virtual and RFID-based pheromones** to generate stigmergic, swarm-like behavior in robots without direct communication. By storing digital pheromones in environmental maps or passive RFID tags, he enabled decentralized coordination and path following, a concept that has attracted attention for its potential in multi-robot systems. Vasiliu’s work is notable for its emphasis on low-power, embedded implementation, making advanced robotics more accessible and practical for real-world applications.
