The LawnMaster OcuMow™ robot mower combines a camera and sensors with Optical Grass Recognition (OGR) software to identify grass and navigate around your lawn without the need for a boundary wire, outdoor power socket or app. Supplied with an MX 24V 4.0Ah battery and fast charger, so it's ready to go out of the box.

RTK is a state-of-the-art geo-positioning technique that enhances the precision of position data derived from satellite-based positioning systems.

Johnson: Kress is a brand that's been around for many years, particularly in Europe, and our parent company Positec acquired the Kress brand back in 2016. We are launching Kress for the first time in North America for outdoor power equipment in the spring.

The robotic mower did not have to stop once to check its position. Even if the Kress RTKn ever does lose signal, the powerful machine uses “dead reckoning.” Dead reckoning is a proprietary system that uses past data plus isometry, odometry, and telemetrics to know its location and keep working.
