Robot mower now Dad’s best friend

Asimo, Hondas advanced humanoid robot (right) introduces the Miimo lawnmower, the companys new product that requires minimal human interaction, and shaves about 3mm of grass at a time, manoeuvering itself on slopes. Miimo goes on sale in Europe next year.

At last – a machine that promises to take the yawn out of cutting the lawn.

A new sensor-equipped lawnmower that works with a combination of controls, timers and real-time sensory feedback was launched this week, and will be ideal for those who want to keep their gardens tidy, but would rather not mow it themselves.

Released by Honda, the technologically advanced machine, Miimo, needs minimal human interaction, and shaves about 3mm of grass at a time, maneuvering itself on slopes. It won’t break potted plants and won’t wander off.

Miimo features a fan that is built into its blade-holder, creating airflow to suck the grass towards the blades.

But unlike traditional lawnmowers, Miimo doesn’t need to collect cuttings, as the clippings it creates are so small, that they are dispersed into the lawn root system, breaking down quickly to act as a natural fertiliser.

It is also fitted with three 360-degree “bump” sensors, which detect obstacles. If the sensor is activated, it will stop, turn and move away.

It can also ascend slopes up to 24 degrees, and when it encounters patches of thick or long grass, it will automatically reduce wheel speed, but maintain blade speed in order to deal with the tough areas.

Miimo can be used on one of three modes – random, directional or mixed – to suit the size and type of garden.

Random mode sees it navigate the lawn without a fixed pattern, while directional mode moves it back and forth in a more uniform fashion to ensure a faster cut.

Mixed mode allows intervals of random and directional cutting. The unique garden tool is also self-sufficient.

Powered by a long-life lithium-ion battery, Miimo is self-charging, constantly monitoring its battery level and returning to its docking station when it needs to recharge.

Owners won’t even have to worry about their lawnmower wandering off since Miimo has been programmed to navigate within a boundary wire that is installed under the ground. It detects the electronic signal in the wire and stays within it.

Miimo’s safety is assured by two “lift” sensors which are triggered if it leaves the garden. On activation, it shuts down completely and sounds an alarm.

It then cannot be used until the owner types in a unique PIN code.

Honda has been working in the development of robotics since 1986, and takes credit for Asimo, the world’s most advanced humanoid robot, but Miimo is the first commercial robotic product manufactured by the company for public use.

It is expected to go on sale in Europe next year for up to E2 500 (R26 260).

Honda SA divisional manager Clinton Lambert said they were still waiting instructions from Japan as to when they would be prepared to supply the South African market.
