SYSTEM AND METHOD FOR STAIR CLIMBING IN A CLUSTER-WHEEL VEHICLE
A system and method for operating a device in ascending or descending stairs. The device has a plurality of wheels ro-tatable about axes that are fixed with re-spect to a cluster arm, where the clus-ter arm itself is rotated about an axis so that wheels rest on successive stairs. The wheels and clus...

| description | A system and method for operating a device in ascending or descending stairs. The device has a plurality of wheels ro-tatable about axes that are fixed with re-spect to a cluster arm, where the clus-ter arm itself is rotated about an axis so that wheels rest on successive stairs. The wheels and cluster arms are controlled ac-cording to separate control laws by a con-troller. Whether the device ascends or de-scends the stairs is governed by the pitch of the device relative to specified front and rear angles. Shifting the center of gravity of the combination of device and payload governs the direction of motion of the de-vice. |
