The invention relates to the field of exoskeleton robots, in particular to a modular reconfigurable multifunctional exoskeleton robot. The modular reconfigurable multifunctional exoskeleton robot comprises a track indoor environment, a multi-degree-of-freedom supporting frame and a whole-body exoskeleton device, wherein the track indoor environment is an open space; a track is arranged on the ground of the track indoor environment; the multi-degree-of-freedom supporting frame is arranged on the track, and translational movement of the multi-degree-of-freedom supporting frame in the axial direction of the whole-body exoskeleton device is achieved; the whole-body exoskeleton device is fixedly connected with the multi-degree-of-freedom supporting frame; the multi-degree-of-freedom supportingframe drives the whole-body exoskeleton device to do translational movement in the axial direction of the track; and the whole-body exoskeleton device achieves translation, pitching and rotation movement relative to the multi-degree-of-freedom supporting frame. The modular reconfigurable multifunctional exoskeleton robot is suitable for multiple visual specific application environments, diversified in functional structure, modular and reconfigurable, and a highly modular reconfigurable multifunctional exoskeleton robot system can be used in combination with a multi-degree-of-freedom rehabilitation auxiliary supporting device to achieve various requirement functions and the rehabilitation effect of approaching closer to the reality.
