A Mecanum wheel-based rocker omnidirectional mobile platform comprises a main body (1), leftwards-rotating Mecanum wheel assemblies (3), rightwards-rotating Mecanum wheel assemblies (5), a rocker suspension I (2), a rocker suspension II (15) and a balancing mechanism (6); the middle parts of the rocker suspension I and the rocker suspension II are hinged to the left and right sides of the main body through revolute joints symmetrically; the middle part of a transverse rocker (8) of the balancing mechanism and one end of the main body are hinged by a revolute joint (10); one end of a side connecting rod I (9) and one end of a side connecting rod II (11) of the balancing mechanism are hinged to the left and right ends of the transverse rocker by spherical joints, and the other end of the side connecting rod I (9) and the other end of the side connecting rod II (11) of the balancing mechanism are hinged to the rocker suspension I and the rocker suspension II by spherical joints; two Mecanum wheel assemblies with different rotation directions are fixed to the two ends of each rocker suspension, and the Mecanum wheel assemblies at the same ends of the rocker suspension I and the rocker suspension II are opposite in rotation directions. According to the invention, wheels are always in contact with the ground and the load is shared, so that the Mecanum wheel-based rocker omnidirectional mobile platform has better motion controllability and terrain trafficability.
