Energy-Time Efficiency in Aerial Swarm Deployment

A major challenge in swarm robotics is efficiently deploying robots into unknown environments, minimising energy and time costs. This is especially important with small aerial robots which have extremely limited flight autonomy. This paper compares three d ...

Energy-Efficient Indoor Search by Swarms of Flying Robots without Global Information

Timothy Stirling

Swarms of robots can quickly search large environments through parallelisation, are robust due to redundancy, and can simplify complex tasks like navigation compared to a single robot. Flying swarms can rapidly cover rough terrain and have elevated sensing ...

2.5D Infrared Range and Bearing System for Collective Robotics

Jean-Christophe Zufferey, Dario Floreano, James Roberts, Timothy Stirling

In the growing field of collective robotics, spatial co-ordination between robots is often critical and usually achieved via local relative positioning sensors. We believe that range and bearing sensing, based on infrared technology, has the potential to f ...
