Understanding Liquid Robotics

Liquid Robotics designs and manufactures autonomous surface vehicles (ASVs) known as Wave Gliders. These innovative robots are capable of traversing vast ocean distances while collecting data on environmental conditions, marine life, and oceanographic phenomena. The key features of Liquid Robotics technology include:

  • Wave Energy Propulsion: The Wave Glider utilizes a unique dual-body design that harnesses wave energy for propulsion. The top float (the “glider”) moves with the ocean surface, while the submerged wing (the “sub”) moves in the opposite direction, generating forward thrust.
  • Autonomous Operation: Equipped with advanced sensors and communication systems, the Wave Glider can operate autonomously for extended periods, allowing for continuous data collection without human intervention.
  • Data Collection Capabilities: The robots are equipped with a variety of sensors to monitor environmental parameters such as temperature, salinity, pH, chlorophyll levels, and marine life presence, facilitating comprehensive ocean monitoring.
