The invention provides a portable upper limb rehabilitation robot and a digital simulation realization method based on LabVIEW. The portable upper limb rehabilitation robot is novel in structure and high in integration degree, can realize auxiliary rehabilitation training on 17 joints including the upper limbs and fingers at the same time, and is attractive in appearance; the three-dimensional visual graphic simulation is realized by utilizing LabVIEW and the PTC-Creo engine technology, the operation is simple, the virtual movement of the rehabilitation robot can be simulated, and an operator can clearly and visually observe the rotating angle of each joint in the simulation process.
