REPLACE – fast delivery in urban environments using drone RElays: PLAnning, Control, and Estimation

This project aims to address several scientific and technological challenges towards fast package delivery in urban environments using drones. As there are severe autonomy constraints to the endurance and travel distance of drones, this project will explicitly consider those limitations and use drone relays to enable effective package delivery to destinations that go beyond the flight range and autonomy of a single drone. Interestingly enough, this raises other scientific challenges in terms of planning of optimal and efficient trajectories for a team of drones deployed throughout a city, for the cooperative control of several drones for package transportation and relay maneuvers, as well as for estimation of vehicles and package location during transportation and relay maneuvers. The research plan will start by addressing single vehicle control and estimation strategies, and progressively evolve into cooperative control, estimation and planning for coordinated relay transportation.

    • Reliable and independent of external sensors and processing units
    • Use hybrid systems and analysis for improved robustness

Application Scenarios

  • Single vehicle in urban and dynamic environments:
    • Focus on single drone parcel pick-up and delivery
    • SLAM in dynamic environments
    • Control methods with interaction with the environment
  • Multiple vehicles with simple relay maneuvers:
    • Cooperative drone delivery with simplified relay maneuver
    • One drone just needs to be above the other for the parcel relay to be possible
