To operate efficiently in urban environments, mobile robots and other automated systems must safely move on sidewalk.Robot is expected to perform tasks such as parcel delivery. At the same time, it is possible The ability to avoid collision with pedestrians or other obstacles. The researchers at the Georgia Institute of Technology and Stanford University (USA) have developed Aliengo - four-legged robots can follow specific routes based on The map, the same ability to avoid collision with obstacles or people. "We have developed a smart four-legged robot that can go on the sidewalk
. Our work is inspired by two sources: automatic driving and indoor robots. However, navigating on outdoor sidewalks usually take place in a multi-walking environment and obstacles, without any instructions. We have proposed a training set of techniques and algorithms to Solving these challenges, "Sehoon Ha - one of the research authors, said
The header, the team to train an artificial neural network to navigate the robot simulation on the sidewalk. The first algorithm is trained using the high-speed simulator. After that, the algorithm creates actual sensor observations similar to the sidewalk image in the real world. By using two-stages has grown, researchers have achieved efficiency. They apply in simulation and then transfer those behaviors to four-foot robots. When evaluated, scientists found that this method works better than other modern models on sidewalk navigation. Later, the group tested in the real world, by operating aliengo robots on the sidewalk in Atlanta.Maks Sorokin - co-authored co-research - said: "In addition to increasing performance from the use of two learning features The stage with the abstract world, surprisingly see how easy the world is easy to enhance / manage our data ". In the process of training, the robot has never seen any States of the sidewalk images as well as the complexity in the real world. Researchers expressed hope that four-legged four-legged robots navigate on this sidewalk can be widely used in the real world
Thus, bringing many benefits to humanity. In the future, four-legged robots developed by these researchers can be used to complete many different tasks, such as parcel delivery or environmental monitoring Urban. In addition, the method they develop can be applied to new or existing mobile robots. Thus, improve the ability to move on the sidewalk of those robots. . Dịch vụ:
