An interactive robot includes an image capturing device, an audio capturing device, an output device, and a processor. The processor is configured to obtain audio information captured by the audio capturing device and image information captured by the image capturing device, recognize a target from the audio information and the image information, confirm basic information and event information of the target and link the basic information with the event information, obtain key information from the event information of the target, implement a neural network analysis algorithm on the key information to confirm an emotion type of the target, search a preset public knowledge database according to the key information to obtain a relevant result, apply a deep learning algorithm on the relevant result and the emotion type of the target to determine a response, and execute the response through the output device.
