Once upon a time, LG made a vacuum cleaner robot. While they've since gotten out of that business, not all is lost. They're now repositioning that technology so as to help the working man out. At the end of a hard day's work, the last thing you really want to do is mow the lawn. So here comes LG to the rescue. A new invention published last week by the US Patent Office reveals that LG has designed a new lawn mower robot. Now they're talking technology that you can appreciate on a hot summer day.
LG's patent FIG. 1 noted below is a plan view for a lawn mower robot; patent FIG. 2 noted in our cover graphic is a perspective view for boundary display apparatuses to be placed on the lawn; and patent FIG. 3 further below is a block view or flowchart relating to the lawn mower robot and how it maps out your lawn area accurately.
LG notes that the robot will be powered by a chargeable and/or dischargeable battery (a second cell). A third power source is reserved for the boundary lamps that will come with the robot. They'll be powered by a photoelectric cell implemented by sunlight.
If you're asking the question, how will the robot know the boundaries of my lawn? Then the answer is clear. LG describes that the unit will come with lamps that you'll be able to lay into your lawn. They'll be able to absorb the sun by day and be used as night lights. These same lamps will double as part of a communications system with the robot. They create the boundaries for the robot to follow via ultrasonic sensors as partly noted in the figure above as #150.
You're given the distinct impression that'll be able to purchase extra lamps if your lawn happens to be oversized.
While the concept of a lawn mower robot appears to be one that's tame, it's really a matter of buyer beware. While the device could be safe under supervision, it could also represent a danger to curious kids and/or pets that want to play with the robot if left unattended.
To be sure, LG's next generation lawn mower robots will have advanced sensory capabilities built in and they'll be designed to avoid the dangers that presented themselves back in 2007. That aside, lawn mower robots will one day rule every neighborhood lawn in the civilized world. Let's just hope that they're quite little beasts.
LG filed their patent application under serial number 564263 back in Q3 2012 and a year earlier in Korea. Considering that this is a patent application, the timing of such a product to market is unknown at this time.
