• Efficient undulating propulsion system

  • Excellent static thrust/Watt

  • Stealth characteristics

  • Amphibious capabilities over sand, snow and solid substrates

  • Resistant to entanglement in plants or other aquatic debris

  • Lower environmental impact than spinning propeller-thrusters

  • Deep sea potential


  • Highly maneuverable autonomous underwater vehicle (AUV) or remotely operated vehicle (ROV) that can move from land to sea and back with ease. Ideal for surf zone, amphibious beach missions and polar ice missions

  • Personal propulsion for professional divers and recreational use

  • Stand-alone thruster to replace propellers on craft in environmentally-sensitive waters such as coral reefs, mangroves and sea grass beds

  • Stand-alone thruster to replace propellers on craft in debris-filled waters

Case Study: Velox -Agile Amphibious Swimmer

Pliant Energy's Velox robot is a beautiful swimmer than can leave the water and travel across sand, pebbles, paving, grass and even ice.


1. Velox deploys away from shore and navigates autonomously below surface or via acoustic modem link to surface craft.

2. Velox swims at or just below surface. Live video feed and/or data to surface craft, aerial drone or satellite for real-time control.

3. Velox transitions seamlessly to land-phase of mission. Live video feed and/or data to surface craft, aerial drone or satellite for real-time control.

Above: Velox maneuvers in free swimming mode under ice (left), increases buoyancy and raises fins for station keeping under ice (right) and activates fins to "skate" across the under surface of the ice.


Above: Velox traveling through plant-filled waters with low risk of entanglement, minimal damage to plants and minimal disturbance of sediment layers.


Above: Velox travels from water to land autonomously or by remote control when near or above the surface with minimal disturbance to environment.
