Abstract

The invention relates to a multi-adaptive wheel and foot switching movable platform and belongs to a combined type movement mechanism. A rack body and shock absorption devices are hinged, thigh structures are connected with the shock absorption devices through rotary shafts, shank structures are connected with the thigh structures through shafts, and wheel type transmission mechanisms are connected with the thigh structures through main shafts placed in thigh sheet holes. The platform has the following beneficial effects that the movable platform is high in carrying capacity and has various advancing treads, and multiple innovation points exist in whole structural design; a foot type structure of the movable platform is high in ground adaptability and obstacle crossing capacity; a wheel type structure of the movable platform is good in flexibility, high in speed and efficiency and capable of achieving ground obstacle avoidance; and two motion states are independent of each other and donot affect each other, wheels and feet can be switched according to the terrain environment, and motion is stable.

Description

technical field [0001] The invention relates to a compound mobile mechanism, in particular to a mobile platform which combines a foot type and a wheel type and can switch freely between the two. Background technique [0002] Mobile robots using a single movement mode are widely used, but the obstacle avoidance ability of the wheel structure and the movement performance on uneven road surfaces are not good; the movement speed of the foot structure is low, the work efficiency is not high, and the operation is not stable. Facing the complex terrain environment, these two leg structures have obvious disadvantages and cannot meet the needs of human production and life. Therefore, a composite mobile mechanism derived from the combination of two or more types of mechanisms came into being. The hybrid leg-wheel-track Azimuth robot developed by the University of Sherbrooke, Canada, and the six-wheeled legged mobile robot ATHLETE designed by the California Institute of Technology , t...
