The article above discusses the recent technological accomplishment made by Boston Dynamics, with funding provided by the US Defense Advanced Research Projects Agency. According to Darpa, the 4 legged robot dubbed "Cheetah", whose running motion mimics that of fast-moving animals in the wild, has set a new robot land speed record of 18mph (29km/h), defeating the former record holder, at 13.1 mph, by a long shot. But the researchers behind the Cheetah have much bigger plans for their rapid robot. Within a year we can expect to see a similar robot that is free running (the current model is dependent on a hydraulic pump), and in four years, a robot that can run in a zigzag pattern and stop abruptly. Ultimately, the goal is to utilize these robots in a war setting where their faster than human speed will provide a significant advantage over enemies. Unfortunately, one limitation of all artificial intelligence diminishes the robots potential; the ability to distinguish between enemies and civilians. I hope to see this technology put to use in various, non-violent, settings in the near future!
