Autonomous Water Sampling & Monitoring USV

An environment monitoring Unmanned Surface Vehicle to autonomously collect water samples and quality data from multiple spots

esm30 sampling 7 e1553845942660

Multi-spot water sampling and monitoring

  • Equipped with a water quality sonde to monitor temperature, conductivity, turbidity, dissolved oxygen, pH, chlorophyll-a and blue green algae.
  • Can collect 4 bottles of 1.8L water samples from different spots  0.5 m under the water’s surface.
  • 4 separated tunnels to avoid cross pollution.

Online water sampling & quality monitoring reports

  • Sampling and monitoring data can be transmitted to the base station in real-time and automatically generate graphical reports.
  •  Assist users to keep track of water quality intuitively and facilitate immediate action to cope with abrupt water pollution.

Automatic mission planning

  • Both the USV and the surveying instruments are controlled by a base station. The USV can autonomously conduct surveys and send back data in real-time.
  • User can also drive the USV manually by a remote controller.

Intelligent collision avoidance

  • With the ultrasonic sensors, the ESM30 USV can detect and bypass obstacles 10 meters ahead to avoid collision.
  • In manual mode, user can observe water environment by the real-time video feed to better avoid obstacles.
