Nomad Lawn Mower Safety
Nomad has many sensors and systems to ensure safe autonomous operations. Over many years, the commercial landscaping industry has developed robust safety standards for outdoor power equipment. Nomad is fully compliant with all of the relevant components of these safety standards.
Nomad Lawn Mower Concept & Design
Nomad is a commercial robotic mower designed to be fully autonomous; It does not require a bounding wire or a manual outside path/headland path to be mowed before being autonomous. Its autonomy allows it to work independently or as part of a crew. The highly redundant sensor suite includes inertial guidance technology, LiDAR, stereo cameras, ultrasonic sensors, and GNSS (GPS). These integrated sensors enable Nomad to stay on the planned path, avoid objects, and maintain safe, high-productivity operations.
Nomad is gas-powered, and the primary traction is through hydraulic ground drive motors within rims fitted with conventional turf tires. Nomad has all-wheel driving and all-wheel steering for the best traction and path-planning flexibility. The steering is provided independently at each wheel that can rotate through 360 °, allowing a very tight turn radius. The mowing deck is a conventional three-spindle deck containing three 20.25” blades. The height of the deck is controlled by linear actuators enabling accurate mowing height between 1.5” to 5.5”.
