Honda has unveiled Miimo its first robotic lawn mower

Miimo uses a microcomputer, timer and sensors to provide automated, unattended grass cutting. Honda’s battery-powered robotic mower delivers quiet operation, recharges quickly, and offers three different programed cutting patterns.

Miimo is available in two models: the HRM 310 and HRM 520. Both models operate within a boundary wire — installed by Honda Power Equipment dealers, underground or on top of the ground around the perimeter of the area to be mowed — using a combination of controls, timers and real-time sensory feedback. Miimo detects the electric field from the wire and stays within the boundary.

Both the HRM 310 and HRM 520 models have independent 360-degree sensors and a floating cover that detect solid contacts between the unit and any obstacles. If a sensor is activated, the lawn mower is designed to stop –when it touches a human or pet, for example – it will turn and move in a different direction from the point of contact. Miimo is equipped with anti-theft protection that will sound an alarm and disengage operation if the mower is lifted from the ground. The unit can only be re-started once the owner enters a unique anti-theft PIN code through an easy-to-use control panel.

Powered by a high-performance lithium-ion battery, Miimo is self charging, constantly monitoring its battery level and returning to its docking station when it needs to recharge. Miimo will recharge when its battery charge registers below 30 percent. The HRM 310 model, with a battery capacity of 22.2 volt can mow for up to 30 minutes on a single charge; the HRM 520 model also is capable of mowing for up to 60 minutes, depending on the complexity of the lawn, on a single charge and has a battery capacity of 22.2V. Each model will self charge in 30 and 60 minutes respectively from a standard power outlet.

Honda’s Miimo robotic lawn mower can tackle virtually any type and shape of lawn, including slopes as steep as 25 degrees. Honda’s robotic mower also navigates smoothly around features like ponds, fences and trees. The Miimo robotic mower has a cutting width of 221mm (8.7 inches) and a cutting height range of 20 to 60 mm (0.8 to 2.4 inches).

The Miimo HRM 310 model weighs 12kg, is capable of cutting up to a 0.20ha and is expected to sell for around $3,300. While the Miimo HRM 520 model, weighing slightly more than 12kg, can cut larger lawns up to a maximum of 0.30ha due to a larger battery, is expected to sell around $3,800. Both models are equipped with high-traction wheels and pivoting steel blades that spin clockwise and counter-clockwise for longer life. Models are currently being rolled out in the northern hemisphere.
