Abstract: The present invention is applied to the human-robot interaction field, and provides a method and apparatus for adjusting interactive directions of robots; the method includes: determining an original direction where a voice signal is generated upon receiving a voice signal; switching a robot from a current direction to the original direction, and capturing a picture corresponded to the original direction; detecting whether a human face exists in the picture; when a human face exists in the picture, determining a required adjustment angle according to a location of the human face in the picture; and adjusting the robot according to the required adjustment angle. Through the above method, the determined location and direction obtained after the adjustment is more precise.

Abstract: A method for automatic obstacle avoidance of a robot includes: obtaining distance values between the robot and an obstacle detected by sensors arranged on a left side, middle part and right side of the robot respectively; when a minimum distance value detected by the sensors on the middle part is less than a threshold value, if a minimum distance value detected by the sensors on either the left side or the right side exceeds an obstacle critical distance, turning the robot 90 degrees towards the side where the minimum distance value exceeds the obstacle critical distance; when the minimum distance value detected by the sensors on the middle part exceeds the distance threshold value, if only the minimum distance value detected by the sensors on the left side exceeds the obstacle critical distance, turning the robot towards the left side by a first angle value.

Abstract: The present invention provides a method for automatic obstacle avoidance of a robot, and this method comprises: according to a depth sensor, obtaining depth data of movable areas of a scene in which the robot lies in; according to a preset depth threshold value, binarizing the depth data; according to an average value or a sum value of binarization processing result of areas, identifying an area where the robot is farther away from an obstacle as a moving direction of the robot. In the present invention, since the depth data is collected, no measurement dead zone is prone to occur; moreover, calculating the average value or the sum value of the binarized depth data only needs to perform a simple comparison, the processing is simpler, the processing speed is fast, and the requirement of the system and the cost are lower.

Abstract: The present invention is applied to the human-robot interaction field, and provides a method and an apparatus for interaction between a robot and a user; the method includes: determining an original direction where a voice signal is generated upon receiving a voice signal; adjusting a robot from a current direction to the original direction, and capturing a picture corresponding to the original direction; detecting whether a human face exists in the picture; when a human face exists in the picture, recognizing whether a user corresponding to the human face is a legal user; and when the user corresponding to the human face is a legal user, interacting with the legal user. The method can improve the accuracy of instruction execution of the robot.

Abstract: The present invention provides a projection method for a robot, the method comprises: receiving a playing command, according to a preset path, obtaining depth data of a projection area corresponding to the robot currently; according to a variation value of the depth data, determining whether the projection area is a flat surface; when the projection area is the flat surface, playing a film according to the playing command. The robot in the present invention can automatically search for the projection area that meets a projection requirement according to depth information of the projection area, such that operation procedures for a user can be greatly reduced, and an applicability of the user can be improved.
