Getting sensors into the ocean, and back

Seagrass Robotics is developing a hybrid aerial-underwater platform to simplify the deployment and recovery of ocean sensors.

Backed by

Our mission

Make sustained robotic presence in the ocean practical.

By simplifying how sensor payloads are deployed, moved and recovered.

The problem

The ocean is still reached the old way.

Reaching the ocean still means a boat, a crew and a short weather window, so most of it goes unmeasured.

  • 01SparseData when a boat can get there, not when it's needed.
  • 02SlowEvery deployment waits on crew, travel and weather.
  • 03ExpensiveVessels and people dominate the cost of each measurement.

The vehicle

Wings out to fly. Swept back to dive.

Scroll to sweep the wings, or drag to turn it.

How it will work

One vehicle. Air and water.

Flight gets the sensor there and back. Underwater, it gets to work.

  1. 01

    Fly out

    Lifts off with the sensor on board and flies to the site. No boat, no crew in transit.

  2. 02

    Dive in

    Sweeps its wings back and enters the water over the site.

  3. 03

    Measure

    The sensor works below the surface for as long as the mission needs.

  4. 04

    Return

    Surfaces, flies home or on to the next site, and is serviced for the next run.

The roadmap

Where we are, and what comes next.

  1. Now

    First full prototype

    Our first complete vehicle, with flight and underwater systems integrated, is being built for its first water tests.

  2. Next

    Reliable operation

    Controlled flight, diving and recovery, repeated under defined conditions.

  3. Then

    A real mission

    A partner's sensor through a defined mission, with measurable gains in access and effort.

  4. Long term

    Persistence

    A cheap, fast way to put machines in the water and keep them there.

Working with us

You bring the instrument. We get it there.

We are looking for researchers, partners and investors, starting with time-sensitive water-column measurements and temporary maritime sensing.
