Huang Zhifeng, an associate professor at Guangdong University of Technology, shows bipedal robot Jet-HR1, outfitted with two jet engines that are strapped to its feet to change the robot's center of gravity, in Guangzhou City, South China's Guangdong Province, March 27, 2018. The Jet-HR1 is just 65cm tall and weighs 6.5kg. Its engines only weigh 232 grams, but they can produce up to 2kg of thrust. Assisted by the jet engines, the robot could cross distances that are 45cm wide, roughly 97 percent of the robot leg's length. In previous studies, only around 20 percent was possible.
