A system and method for autonomous navigation. The system includes a computing device having a processor and a storage device storing computer executable code. The computer executable code, when executed at the processor, is configured to: provide a planned path having intersections in an environment, where the intersections and roads therebetween are represented by sequential place identifications (IDs); receive images of the environment; perform convolutional neural network on the images to obtain predicted place IDs; when a predicted place ID of a current image is next to a place ID of a previous image, and is the same as predicted place IDs of a predetermined number of following images, define the predicted place ID as place IDs of the current and the following images; and perform autonomous navigation based on the planned path and the image place IDs.

System and method for recognizing intersection by autonomous vehicles

A system and method for autonomous navigation using a visual sparse map. The system includes a robotic device having an RGB-D camera, a processor and a storage device storing computer executable code. The computer executable code is configured to: obtain the visual sparse map based on captured RGB-D images; capture an RGB image; acquire a current pose of the robotic device; find a keyframes nearest to the current pose of the robotic device; find a target waypoint that is ahead of the nearest keyframe at about a pre-defined distance; compute transition velocity and rotation velocity of the robotic device based on relative location between the robotic device and the target waypoint; and control operation of the robotic device using the computed transition velocity and rotation velocity to achieve autonomous navigation.

System and method for autonomous navigation using visual sparse map

A mobile robotic device and a method for controlling the mobile robotic device to move are provided. The mobile robotic device includes: a body; a rotatable portion connected to the body and configured to support the body in a rotatable manner; and an operational portion which comprises at least two arms connected to the body and configured to support the body in a walkable manner. In operation, the mobile robotic device is switchable between a manipulation mode in which the rotatable portion supports the body in the rotatable manner and a locomotion mode in which the at least two arms support the body in the walkable manner.
