1. A modular omnidirectional motion platform, comprising a driving type omnidirectional motion chassis, and a driving unit and a protection support mounted on the driving type omnidirectional motion chassis, wherein
the driving type omnidirectional motion chassis comprises a chassis bottom plate, and a plurality of longitudinal elongated speed decomposition units are mounted on the chassis bottom plate; and the speed decomposition units comprise left-rotating speed decomposition units and right-rotating speed decomposition units;
a rotational speed of each of the left-rotating speed decomposition units is the same; a rotational speed of each of the right-rotating speed decomposition units is the same; all the left-rotating speed decomposition units and the right-rotating speed decomposition units are alternately arranged in a parallel manner; the left-rotating speed decomposition units have different lengths; and the right-rotating speed decomposition units have different lengths; and
each of the speed decomposition units comprises a load-bearing shaft and rotating shafts fixed around the load-bearing shaft; parallel transmission assemblies are disposed on the load-bearing shafts of the speed decomposition units, adjacent two of the left-rotating speed decomposition units are connected by one parallel transmission assembly, and adjacent two of the right-rotating speed decomposition units are connected by one parallel transmission assembly; at least one of the left-rotating speed decomposition units serves as an active left-rotating speed decomposition unit, and the active left-rotating speed decomposition unit rotates and transmits through the parallel transmission assemblies, such that all the left-rotating speed decomposition units rotate together at a same speed in a same direction; and at least one of the right-rotating speed decomposition units serves as an active right-rotating speed decomposition unit, and the active right-rotating speed decomposition unit rotates and transmits through the parallel transmission assemblies, such that all the right-rotating speed decomposition units rotate together at a same speed in a same direction.
