Bad guys everywhere, beware – even a high wall won’t deter governments and their dedicated military machine from hunting you down. The latest progress in the robotics department results in a military robot which is able to clear obstacles more than 7.5m (25 feet) in height – and this is despite the fact that the robot itself is roughly the size of a shoebox, relying on a quartet of wheels to get around. Sorta like a mechanical flea, don’t you think? Dubbed the Precision Urban Hopper, it relies on a piston-actuated “leg” that propels it over obstacles including walls or fences. The Precision Urban Hopper will be guided via GPS and would come in handy for surveillance purposes in urban environments. Expect delivery of these puppies to happen sometime later next year.
