Abstract
The invention discloses an octahedral moving mechanism with arc-shaped rods and full revolute pairs. The moving mechanism comprises first to sixth vertex assemblies and first to twelfth branched chains, the four U-shaped brackets on each vertex are respectively connected with one ends of the four branch chains through rotating shafts to form a revolute pair; the structures and the sizes of the four vertex assemblies are the same; the twelve branched chains are the same in structure and size; the appearance of the connecting moving mechanism is in a regular octahedron shape; the purposes of deformation and movement of the octahedral mobile robot are achieved by controlling forward rotation and reverse rotation of the steering engines to drive the branch chains to turn inwards and outwards. In addition, through the design of the arc-shaped rod, the purposes of reducing contact impact with the ground in the moving process and protecting the machine body can be achieved. The invention can be used for reconnaissance and carrying.
