Prometheus Rainbow 2


Reconfigurable with a unique folding wing design that enables it to contract before and during deployment and expand prior to flight.

Confined Operation

Operate in a confined space e.g. tunnels and caves, due to the stability enabled through AI.

GPS Denied

Operate underground in GPS denied environments.


Can carry a payload of 3D LiDAR which can be customized with additional thermal and optical cameras.


Operate in unknown environments beyond visual line of sight (BVLoS).


Operates autonomously navigating and exploring unknown spaces using advanced AI techniques.


Operate in total darkness and low light conditions.

Size & Deployment

Can be deployed down a 150mm access pipe or bore hole.

Consortium Overview

Prometheus has been designed, built and tested by a consortium led by Headlight AI, an SME working with leading edge sensor and data processing technologies. Partners include Network Rail, an end user which will use the robot to explore and map mine workings that extend under existing rail infrastructure; Callen-Lenz an SME with expertise in airborne robotic systems development and deployment; Thales who provide expertise in sensors and adaptive sensing software and the Universities of Manchester, Royal Holloway and Bristol who have integrated the latest sensors, control and manufacturing techniques and Advanced AI into a novel and highly capable platform.
