Robotic lawn mower concepts from South Korea

PCM-401 robotic lawn mower concept

Advanced Technology Korea weblog published an article yesterday about the importance of industrial design. To prove her point the author cited several examples from the winners of the Korea Design Exhibition, and one of these was an automatic lawn mower concept. The robot concept, introduced and awarded at the 44th Korea Design Exhibition in 2009, had never passed the CAD rendering phase and was forgotten after the event.

The crash helmet-shaped PCM-401, as the designers have named it, had a small docking station and a solar panel behind the dark cover that could provide extra energy for the device to extend the length of working time. Unlike all the other robotic lawn mowers on the market, the PCM-401 was designed with a cutting cylinder (instead of blades) for scissor-like cutting that is known to provide a nicer, healthier cut. The robot could work with or without a grass clipping collector bin, and was designed to navigate using a GPS module. The designers described the product as something that they could see selling well overseas.

While I was researching this concept I came across another South Korean robotic lawn mower that was showcased in mid-2008. The Muwi, as they called it, was a cylinder-shaped mower that cuts, collects and compacts the grass as it intelligently covers the area. Information is scarce on this unit, but it sounds mostly like an idea to get rid of the clippings that all the other robotic lawn mowers leave on the area. Although there is no picture available of the bottom of the device, from the wide cutting path shown on the drawings, I would guess it was designed with a cylinder-shaped cutting unit. Muwi won the IDEA Bronze Design Award in 2008, but as far as I know, it wasn't built to be a commercial robot either.
