The robo scouts can remain at sea for months using wind, solar and wave power.
The project is the biggest of its kind ever in Britain and could herald a new era in ocean exploration as the vehicles are designed to operate remotely across the oceans for months using wind, solar and wave power.
Natural England has designated the Isles of Scilly as National Character Area 158.
The Isles of Scilly form an archipelago of five inhabited islands and numerous other small rocky islets (around 140 in total) lying 45 km (28 mi) off Land's End.
Three innovative machines are tracking tagged fish and monitoring the sea.The Isles of Scilly are an archipelago off the southwestern tip of the Cornish peninsula of Great Britain.Although the Isles of Scilly are still part of the ceremonial county of Cornwall, and some services have been combined with those of Cornwall, since 1890 the islands have had a separate local authority.Liquid Robotics Waveglider is a solar and wave powered autonomous monohull that is simple and robust, save for the underwater fin assembly that might have been inspired by a Venetian blind or kite, as mush as a fish tail.We will be most interested to learn of the energy generated by the Ampair wind turbine, where it is mounted so low.The three robot boats will spend about two weeks tracking 85 plaice, sole, brill, and rays caught and tagged by the MBA and released yesterday.
