Yarbo modular yard robot mows grass, clears snow and blows leaves

There are already several autonomous robots that mow grass, and even a few that clear snow. The modular Yarbo robot, however, can tend to both grass and snow, plus it can blow away dead leaves or other debris.

Currently the subject of a Kickstarter campaign, the device was designed by the same people who previously brought us the Snowbot S1 snow-blowing robot. The Yarbo consists of a motorized rubber-tracked base unit, which can be equipped with any of three system-specific modules.

The Lawn Mower module is equipped with two spinning blades placed side-by-side, giving it an adjustable grass-cutting width of up to 20 inches (508 mm). Users can also adjust the cutting height, from a range of 1.2 to 4 inches (30 to 102 mm).

The Snow Blower module features a powered auger – which draws in dry, wet or packed snow up to 12 inches deep (305 mm) – along with an impeller which shoots that snow out of an adjustable-direction chute on top. It has a snow-gathering width of 21 inches (533 mm), and it can throw snow in any direction from 6 to 40 feet (1.8 to 12.2 m).

Finally, the Blower module sports an underside fan nozzle that delivers a leaf-blowing breeze of up to 119 mph (192 km/h). The air volume and speed can be adjusted via an accompanying app.

All three modules incorporate a millimeter-wave radar unit and a camera, which allow them (and the attached robot) to detect and avoid obstacles. The Yarbo orients itself within a predefined mowing/blowing area via GPS – plus it determines what path to follow in order to cover that area most efficiently – so it doesn’t require perimeter wires or beacons like some other lawn-mowing robots.

It can also climb slopes with a grade of up to 68 percent, and automatically returns to a docking station when its job is done. The robot’s 36V/38.4-Ah lithium-ion battery is then wirelessly recharged. That battery operates at temperatures down to -30º C (-22º F), plus it can be removed from the Yarbo and used on its own as a portable power station.

One 2-hour charge is claimed to be good for two hours of mowing, 90 minutes of snow-blowing (at a snow height of 5 in/127 mm), or 50 minutes of leaf-blowing.

The Yarbo can be remotely monitored and/or activated via a 4G connection, plus it can be manually controlled in real time via a Wi-Fi-connected smartphone running its app

Pledges run from US$2,599 for a Yarbo with a Lawn Mower module (estimated retail $4,399), all the way up to $3,699 for a robot with all three modules (retail $6,999). Assuming it reaches production, deliveries should take place in December. Plans call for other modules to be offered in the future, such as sweeper, sprinkler and snow plow units.
