A visual imitation-based robotic sequence task learning method for instructing robots to imitate human actions from videos containing them. The steps are: (1) According to the input image, use the region-based mask convolutional neural network to identify the object type and mask; (2) Calculate the actual plane physical coordinates (x, y) of the object according to the mask; (3) Identify the target Atomic actions in the video; (4) convert the atomic action sequence and the recognized object type into a one-dimensional vector; (5) input the one-dimensional vector into the task planner, and output a task description vector that can guide the robot; (6) Combining the task description vector and object coordinates, the robot is controlled to complete the robot's imitation of the sequence tasks in the target video. The invention takes videos and images as input, recognizes objects and infers task sequences, and guides the robot to complete the imitation of the target video. At the same time, it has strong generalization and can still complete the imitation tasks under different environments or object types.
