Crabpilot

Robot workers for the field.

Bring us a problem on a farm, an industrial site or a mission. We solve it with our machines, with yours, or with both working as one team.

UGV1, a four-wheeled metal ground robot, on a field of grass

How a job runs

One looks from above, one does the work on the ground, and one person directs both.

  1. Find it

    UAV1 flies over the field or site and marks what needs doing.

  2. Go there

    The ground vehicle drives to each mark, on a route it knows to the centimetre.

  3. Do the work

    With the tool the job needs: a sprayer, a sensor, a load.

Today one station runs both machines. Tools, and the drone handing a spot to the ground vehicle, are what we are building next.

Our machines

UGV1 and UAV1 work today and UGV2 is on the way. Each is built to carry a tool.

Already have machines?

If your drone or ground vehicle runs ArduPilot or PX4, it joins the same team as ours, on the same station. Anything else, we look at with you.

Problems we solve

Three examples of how we would put the machines to work. Each one starts with your problem and runs in simulation before it runs on your ground.

On the farm

Treat the weeds, not the whole field.

How we would do it: UAV1 flies over and marks the patches that need work. The ground vehicle drives to each one and treats only that spot.

Works today: mapped routes on RTK and flights with the camera. Tested in simulation: weeding a crop row scored end to end. Next: the spot-treatment tool, the drone-to-ground hand-off (in simulation first) and a pilot on your field.

On an industrial site

Daily rounds without the walking.

How we would do it: UAV1 checks the fence line or the panel rows from above. The ground vehicle does the rounds on a route it has learned, carrying sensors or parts. Machines you already run on ArduPilot or PX4 join the same station.

Works today: learned routes, coming home on its own, command over Starlink and machines on ArduPilot or PX4 joining. Next: the sensor kit and a pilot on your site.

On a mission

Nobody on the dangerous stretch.

How we would do it: UAV1 scouts the route ahead. The ground vehicle carries the supplies along it, and several can follow one another.

Works today: learned routes, coming home on its own and centimetre positioning. Tested in simulation: three vehicles in formation. In development: finding the way when GPS is weak. Next: a military mesh radio for the link and a pilot with a unit.

Where we are

We say plainly what works today and what we are still building.

Works today

  • UGV1 on real routes: taught routes, map missions, coming home, centimetre positioning
  • UAV1 flying missions on its own, with its camera
  • UAV1: 30 minutes a flight with the camera
  • One station running both machines
  • Machines on ArduPilot or PX4 joining the team

Tested in simulation

  • Three vehicles driving in formation, within 0.1 m
  • A fleet run from one station, every vehicle’s link watched
  • Vehicles sharing out a job among themselves
  • Weeding a crop row, scored end to end

Still building

  • UGV2
  • Tools that switch on along the route
  • Stopping for obstacles, so a run can go unattended
  • Finding the way when GPS is weak
  • First pilots on farms, industrial sites and with defence users, each tried in simulation first
  • A military mesh radio for the link
  • A UGV2 data sheet, once it is measured

Put them to work on your problem.

Bring us a field, a site or a mission. We will show you what the machines would do with it.
