Abstract: The present disclosure provides a robot mapping method as well as a robot and a computer readable storage medium using the same. The method includes: detecting a marker with identification information capable of being identified by the robot in a current scene; determining whether the detected marker meets a preset condition; and mapping the current scene based on the marker, if the detected marker meets the preset condition. The robot mapping method can not only map the current scene, but also effectively reduce the difficulty of loops and the number of false loops.

Abstract: The present disclosure discloses a voice conversion method. The method includes: obtaining a to-be-converted voice, and extracting acoustic features of the to-be-converted voice; obtaining a source vector corresponding to the to-be-converted voice from a source vector pool, and selecting a target vector corresponding to the target voice from the target vector pool; obtaining acoustic features of the target voice output by the voice conversion model by using the acoustic features of the to-be-converted voice, the source vector corresponding to the to-be-converted voice, and the target vector corresponding to the target voice as an input of the voice conversion model; and obtaining the target voice by converting the acoustic features of the target voice using a vocoder. In addition, a voice conversion apparatus and a storage medium are also provided.

Abstract: A building block includes at least one of a plug portion and a socket portion. The plug portion has two cantilevered tongues deflectable toward each other. Each cantilevered tongue includes a first engaging portion. The socket portion defines a chamber and has two second engaging portions. The plug portion and the socket portion are configured in such a way that the plug portion of one building block is insertable into the chamber of the socket portion of another building block, and the two cantilevered tongues of the building block deflect toward each other after insertion of the plug portion of the building block into the chamber of the socket portion of the other building block, which allows the first engaging portions of the building block to be engaged with the second engaging portions of the other building block, thereby connecting the two building blocks together.

Abstract: The present disclosure provides a joint control method for a serial robot and a serial robot using the same. The method includes: performing a analysis on an end joint in the plurality of joints, and calculating the force of the previous joint acting on the end joint; performing a analysis on each of the other joints in the plurality of joints, and calculating the force of the previous joint acting on the joint; obtaining an angular velocity and an angular acceleration of each joint after obtaining the force of the previous joint acting on the joint, and calculating a torque corresponding to each joint; and projecting the torque corresponding to each joint to a motor corresponding to the joint to obtain a torque to be applied to the motor at a current time. In this manner, which improves the tracking precision of the end joint while reduces the tracking error.

Abstract: A foot of a robot includes a lower plate, a first infrared transmitting and receiving unit and a circuit board electrically connected to the first infrared transmitting and receiving unit that are arranged on the lower plate. The first infrared transmitting and receiving unit is arranged in such a way that infrared light transmitted from and received by the first infrared transmitting and receiving unit travels in paths that are inclined with respect to the lower plate toward an area in front of the foot when the lower plate is substantially horizontal, so as to detect existence of a footing.
