Roland Piquepaille writes "In 'Robot pummels roads with water', the Augusta Chronicle says that a hydrodemolition robot is going to restore seven bridges in Georgia. "It's a robot that destroys everything in its path with a crushing stream of water 15 times more powerful than a jackhammer. The robot looks like a street cleaner machine on steroids and is expected to begin use August 1 to resurface seven bridges on Gordon Highway from Walton Way to the bridge at the South Carolina state line." This kind of robot needs only two workers to operate it, instead of 15 workers for a jackhammer, is less noisy and more gentle for the foundations. You'll find more details in this summary."
