The innovative Stiga A1500 system

A major innovation in lawn care, Stiga introduces the A1500 Autonomous Lawnmower Robot, which combines GPS RTK with patented Active Guidance System (AGS) technology. The two systems promise to improve 4G signal reliability, thus overcoming even the most challenging obstacles such as walls, fences and hedges that can reduce signal quality. The Stiga A1500 learns and remembers where GPS reception is weak or interrupted and detects if there are blind spots in the garden. Using this information the machine plans the most efficient route each day, predicting where and when to cut the grass. By stabilising the connection with the station along the entire route, the robot ensures - says the Veneto-based company - that each area of the lawn is cut regularly and accurately, without passing over the same areas several times. Presenting the machine, Stiga CEO Sean Robinson said, "Mapping and storing data about the garden is not enough to ensure truly autonomous lawn maintenance. Our engineers have challenged everything that both Stiga and other manufacturers have done before with robot lawnmowers to come up with truly integrated and innovative solutions." Indeed, the A1500 uses GPS-based virtual mapping instead of perimeter wires. The lack of physical boundaries makes it possible to change the perimeter seamlessly, according to the layout of the garden. The perimeter can be modified via the Stiga GO app, which also allows you to check the operation and status of the robot. Via the app, it is also possible to manage a number of other options, such as configuration, programming, zoning, cutting patterns, cutting height adjustment, as well as signalling obstacles and areas to avoid. Depending on the model, the mower is equipped with four or six rotating carbon steel blades, which rotate at up to 2,850 rpm. The blade sharpening and the short cutting cycles - two per day - allow the grass to heal and recover naturally.
