Roman Ibrahimov, Jannik Matthias Heinen
A multi-robot system leverages bioinspired tactile sensing and a distributed optimization framework to explore and map unknown 2D environments, offering a robust alternative to optical sensors in perceptually degraded conditions. The system collaboratively constructs obstacle maps by logging collision points, demonstrating efficient, collision-free exploration when prioritizing inter-robot collision avoidance over redundancy minimization in simulations.
Key insights
- Prioritizing collision avoidance (higher β value) over redundancy minimization (lower γ value) in the cost function leads to the most efficient exploration, characterized by zero robot collisions and faster mapping times.
- Tactile sensing, by directly recording physical contact points, provides a robust method for obstacle mapping, particularly useful in environments where optical sensors are ineffective or unreliable.
- Increasing the number of robots generally enhances mapping efficiency up to an optimal point (7 robots in the tested environment), beyond which coordination complexities can lead to diminishing returns in logged points per second.
