Having been invited to the Toulon Provence Regatta battle boat, I was able to gather the expectations of the president of the Toulon robot school regarding the difficulties in maneuvering the scale models from a distance. Indeed when going around buoys, visibility being very restricted, maneuvers could be greatly facilitated by a subjective stereoscopic video preview of the drone for a dockside operator equipped with a virtual reality headset. The challenge will consist of setting up the electronic elements for video capture, signal transmission, decoding and real-time reception on the operator's headset.
