Remote-controlled lawnmowers are far from a new idea. People have been cutting grass from the comfort of a lawn chair for years now. But what if you needed to clear the side of a steep hill or obliterate some nasty weeds without ever getting up? That's when you'll need the intimidating half-tank half-mower called the TREX.
Weighing in at 245kg the TREX -- short for terrestrial robotic explorer -- can handle slopes as steep as 50 degrees thanks to a pair of grippy treads that can even handle snow. Its cutting blades and drivetrain are powered by a hybrid gas/electric powertrain, and it's frighteningly fast. If you were hoping to make short work of your chores with a TREX at home, you'll have to cough up a hefty $30,000, but from the looks of it you won't be disappointed. [EvaTech]
