The Raptor robot has broken the speed record with an impressive 46 km/h. It was developed by the Korea Advanced Institute of Science and Technology (KAIST). The bipedal Raptor uses a unique “tail” that acts as a counterweight to help keep its balance while running. This element is more like a pole to keep it upright. The weight of the steel “raptor” is 3 kg. The main advantage of the Raptor is its ability to overcome obstacles on the way, while maintaining high speed. According to the authors of the project, this development represents an important step in the creation of ultra-fast bipedal robots.
