Abstract

Claims (36)

1. A tote configured to be transferred by a tote transfer mechanism of a mobile robot between the mobile robot and first and second storage shelves on opposed sides of the mobile robot, the tote comprising:

a center of gravity and a side configured to be oriented parallel to an axis of transfer of the tote between the mobile robot and the first and second storage shelves;

a first surface on the side of the tote configured to be engaged by a first finger to exert a first pulling force on the tote in a direction away from the center of gravity of the tote, the first pulling force affecting transfer of the tote from the first storage shelf to the mobile robot, and

wherein the first surface is configured to be engaged by the first finger to exert a second pulling force on the tote in a direction away from the center of gravity of the tote, the second pulling force affecting movement of the tote from the mobile robot toward the second storage shelf and

a second surface on the side of the tote configured to be engaged by a second finger to exert a first pushing force on the tote in a direction toward the center of gravity of the tote, the first pushing force completing transfer of the tote from the mobile robot to the second storage shelf;

wherein the first surface is a vertical surface inside a pocket formed on the side of the tote; and

wherein the second surface is a surface outside of the pocket.

2. A tote configured to be transferred by a tote transfer mechanism of a mobile robot between the mobile robot and first and second storage shelves on a same side of the mobile robot, the tote comprising;

a center of gravity and a side configured to be oriented parallel to an axis of transfer of the tote between the mobile robot and the first and second storage shelves;

a first surface on the side of the tote configured to be engaged by a first finger to exert a first pulling force on the tote in a direction away from the center of gravity of the tote, the first pulling force affecting transfer of the tote from the first storage shelf to the mobile robot;

a second surface on the side of the tote configured to be engaged by the first finger to exert a first pushing force on the tote in a direction toward the center of gravity, the first pushing force moving the tote toward the second storage shelf; and

a third surface on the side of the tote configured to be engaged by a second finger to exert a second pushing force in the direction toward the center of gravity, the second pushing force completing movement of the tote onto the second storage shelf;

wherein the first surface is a flat surface inside a pocket formed on the side of the tote; and

wherein the third surface is a surface outside of the pocket.

3. A tote configured to be transferred by a tote transfer mechanism of a mobile robot between the mobile robot and first and second storage shelves on opposed sides of the mobile robot, the tote comprising:

a center of gravity and a side configured to be oriented parallel to an axis of transfer of the tote between the mobile robot and the first and second storage shelves;

a flat surface on the side of the tote configured to be engaged by a first finger to exert a first pulling force on the tote in a direction away from the center of gravity of the tote, the first pulling force affecting transfer of the tote from the first storage shelf to the mobile robot, and

wherein the flat surface is configured to be engaged by the first finger to exert a second pulling force on the tote in a direction away from the center of gravity of the tote, the second pulling force affecting movement of the tote from the mobile robot toward the second storage shelf, and

a concave surface on the side of the tote configured to be engaged by a second finger to exert a first pushing force on the tote in a direction toward the center of gravity of the tote, the first pushing force completing transfer of the tote from the mobile robot to the second storage shelf;

wherein the flat surface is a vertical surface inside a pocket formed on the side of the tote; and

wherein the concave surface is a surface outside of the pocket.

4. The tote of claim 3 , wherein the concave surface is at an end of the tote adjacent the side of the tote.

5. A tote comprising:

a center of gravity and a side configured to be oriented parallel to an axis of transfer between a mobile robot and first and second storage shelves;

a flat surface on the side of the tote configured to be engaged by a first finger and the first flat surface is configured to receive a first pulling force on the tote by the first finger in a direction away from the center of gravity of the tote, the first pulling force affecting transfer of the tote from the first storage shelf to the mobile robot;

a first concave surface on the side of the tote configured to be engaged by the first finger and the first concave surface configured to receive a first pushing force on the tote by the first finger in a direction toward the center of gravity, the first pushing force moving the tote toward the second storage shelf; and

a second concave surface, on the side of the tote, configured to be engaged by a second finger and the second concave surface configured to receive a second pushing force by the second finger in the direction toward the center of gravity, the second pushing force completing movement of the tote onto the second storage shelf;

wherein the flat surface is a vertical surface inside a pocket formed on the side of the tote; and

wherein the second concave surface is a surface outside of the pocket.

6. The tote of claim 5 , further comprising an angled surface inside the pocket and extending from the flat surface.

7. The tote of claim 5 , wherein the second concave surface

is at an end of the tote adjacent the side of the tote.

8. The tote of claim 5 , wherein the first concave surface is a surface inside of the pocket.

9. The tote of claim 5 ,

wherein the flat surface is a first interior surface of the pocket; and

wherein the first concave surface is a second interior surface of the pocket.
