Patent ID: 8607902

Claim:
A width variable structure of a moving and transport means using mecanum wheels, comprising: a plurality of mecanum wheels; a plurality of links connecting the mecanum wheels; and a plurality of motors wherein at least one motor is mounted on each of the mecanum wheels and is operably connected to at least one link of the plurality of links to transfer driving forces to the links, respectively and then to the mecanum wheels, wherein the plurality of mecanum wheels includes: a first mecanum wheel positioned on a front left side of the width variable structure; a second mecanum wheel positioned on a front right side of the width variable structure; a third mecanum wheel positioned on a rear left side of the width variable structure; and a fourth mecanum wheel positioned on a rear right side of the width variable structure, and wherein the plurality of motors include: a first motor mounted on the first mecanum wheel, the first motor transferring power through one or more of the plurality of links to the first mecanum wheel; a second motor mounted on the second mecanum wheel, the second motor transferring power through one or more of the plurality of links to the second mecanum wheel; a third motor mounted on the third mecanum wheel, the third motor transferring power through one or more of the plurality of links to the third mecanum wheel; and a fourth motor mounted on the fourth mecanum wheel, the fourth motor transferring power through one or more of the plurality of links to the fourth mecanum wheel, and wherein the plurality of links include: a first link connected to the first motor; a second link connected to the second motor; a third link connected to the third motor; and a fourth link connected to the fourth motor, wherein the first, second, third and fourth links all connect to the linkage to transfer to the linkage force from one or more of the mecanum wheels to fold the linkage based upon which of the one or more mecanum wheels are moving.
