| Abstract: |
A human assisted walking robot formed by a motor, a cargo bin, a pair of legs mounted to the carrier; and a stabilizing support mounted at its proximal end to the carrier and having a wheel rotatably mounted to the distal end. The motor drives the first and second leg members resulting in a walking motion. Each leg is formed by a thigh link and a shank link. A four-bar linkage is coupled between the motor and the thigh and shank of each leg so that rotational motion generated by the motor produces a walking motion by the legs.

First Claim:
Show all 47 claims |
What is claimed is:
1. A mechanical transportation device comprising:
- a carrier member having a top side for supporting a load and an underside;
- a first leg member rotatably coupled to the underside of the carrier member;
- a second leg member rotatably coupled to the underside of the carrier member proximate to the first leg member and configured to move relative to the first leg member;
- a handle member for use by an operator to stabilize the device; and
- an onboard power unit for powering the first leg member and the second leg member to move relative to each other in a walking motion;
- wherein the walking motion provides locomotion for the transportation device; and
- wherein the transportation device is unstable without the support of the operator.
