Oh, patents! The Skypod (2)

 Copyright © Françoise Herrmann

Autonomous Exotec Skypods dance their 3D way around warehouses, climbing up and down shelves to towering heights, swiveling around as if mounted on ball-bearings. The following video (viewable only on Youtube) offers a Skypod choreography to the tune of Edvard Grieg’s (1875) orchestral piece for Scene 6, Act II of Henrik Ibsen’s (1867) play Peer Gynt (1).

The Skypods also move around with a visible stability, regardless of the presence, absence or position of the load transported in the payload crate. The US family member utility patent US2019263463A1, titled Automatically guided trolley for transporting and/or handling a load, discloses an invention that precisely addresses the load-bearing issue, relative to equilibrium, speed and energy-efficiency, including the corollary issue of swiveling-capacity.

In a nutshell, the invention disclosed replaces the typical 4-wheel drive suspension system of a vehicle. The invention system comprises two frames: one receiving the payload, and the other in contact with the ground, supporting the payload-receiving frame. The supporting frame further comprises two connected walking beams at the front and rear of the Skypod autonomous vehicle (termed automated trolley), connected to two idler wheels and two drive wheels. Translation of the two walking beams is designed to distribute the payload weight, received by the main frame, evenly between all wheels, idle and drive, at the front and rear of the vehicle, as well as left and right. The walking beam system is also much lighter, thus promoting enhanced vehicle performance. both in terms of speed and energy efficiency.

For those skilled in the art, the abstract of this patent, hyperlinked to the complete disclosure of the invention, is included below, together with the patent Figure 1, showing an exemplary embodiment of the invention. In particular, the patent Figure 1 depicts the Skypod vehicle (guided trolley)  10,  comprising a supporting frame 12 and main load-receiving frame 11, idle wheels 18 and driver wheels 16, engine 17, and the two walking beams 13 and 14, connected to the supporting frame 12, with translation arms (132, 142), and (131, 141), contributing to evenly distribute a payload weight to all the wheels. In sum, a new mechanical load-bearing-and-distributing system, enabling the visible stability, and calculated efficiency, of the autonomous Skypod vehicle.

An automated guided trolley for transporting and/or handling a load. The trolley has a main frame for receiving the load and a supporting frame having two walking beams extending respectively towards the front and the rear of the trolley. The walking beams are mounted rotatably with respect to the main frame respectively about a first axis and a second axis and such a walking beam includes elements for securing one arm of one walking beam to one arm of the other walking beam and for supporting the first of these arms on the other arm.
