Autonomous OMAV Flight in Confined Spaces
In this project the student will integrate the Voliro omnidirectional multi-aerial vehicle (OMAV) recently spun off from the lab with a navigation stack. The aim is autonomous flight in confined spaces such as doorways and narrow passages. Good results may see use in a high-profile research project
The Voliro [1] is omnidirectional and can tilt to fly in both horizontal and vertical configurations (see image). This allows the vehicle to squeeze through doors and narrow passages that are normally too narrow for standard aerial vehicles of this size. For this purpose we are equipping it with a state-of-the-art sensor and navigation stack developed by the lab for the DARPA Sub-T challenge [2-3], including high-res LIDAR and cameras.
While the sensors will already be mounted on the platform, they need to be integrated with the navigation stack. The navigation stack will also require modifications to work when the Voliro flies sideways in such a configuration. In particular, planning trajectories through confined spaces such as doorways, while taking into account the Volio’s unique flight configurations, in addition to sufficient LIDAR visibility for safe navigation. This would likely build on some existing UAV motion planner (see e.g. [4-6]). The entire design needs to be validated by real flight tests with the Voliro.
