Abstract

The application provides an external force determination method, device, robot and computer readable storage medium. The external force determination method comprises: acquiring first force information of a mechanical arm; determining a working scene of the mechanical arm according to the first force information and / or a first image, the first image being an image obtained by photographing the mechanical arm; and determining information of a task force according to the working scene, the task force representing a force that needs to be overcome by the mechanical arm to complete a task; so that the task force determination method corresponds to the working scene, the accuracy of the obtained task force is improved, and then the information of the external force received by the mechanical arm can be accurately determined through the information of the task force and the first force information of the mechanical arm.
