The invention relates to an artificial-intelligence exercise assisting device. The artificial-intelligence exercise assisting device is mainly used for lower-limb walking assisting and lower-limb rehabilitation training. According to the technical scheme, the artificial-intelligence exercise assisting device comprises a structure supporting system, sensors, sensor circuits, a signal processing system (a mobile calculation platform), a driving executing device, a power system and a walking stick. The artificial-intelligence exercise assisting device has the advantages that the dilemma that movement of the lower limbs of a paralysis patient, a hemiplegic paralysis patient, a fracture patient and an old bone joint retrogressive disease patient is inconvenient is overcome. A user wears an exoskeleton wearing assisting device, human body signals and the assisting device interact with each other and are matched, the human body transmits a control command to the exoskeleton wearing assisting device, exoskeleton detects the human body signals, a proper command is obtained after artificial intelligence calculation, then driving mechanisms provide energy required by movement for the lower limbs of the human body, and the finally the effect that artificial intelligent and mechanical force are supplemented and interacted is achieved. According to the artificial-intelligence exercise assisting device, the human body control signals and the artificial intelligence of a machine are fused, the balance of the gravity center of the human body is controlled, and mild control over the exoskeleton assisting device is obtained.
