Abstract

The invention discloses a mobile robot configured for delivering consumable items to delivery recipients. The mobile robot comprises an item compartment with a top section, a separator, and a bottom section. The mobile robot also comprises a temperature control component. The invention also discloses a method for delivering consumable items to delivery recipients using the mobile robot.

First claim

We claim:

1 . A mobile robot configured for delivering consumable items to delivery recipients, the mobile robot comprising:
a body comprising an item compartment, wherein the item compartment comprises:
a top section configured to hold at least one heated consumable item;
a bottom section configured to hold at least one of:
at least one cooled consumable item; and/or
at least one temperature-neutral consumable item;

a separator configured to separate the top section and the bottom section; at least one temperature control component configured to maintain at least one of:
a temperature exceeding ambient temperature in the top section; and/or
a temperature below that of the top section in the bottom section.

2 . The mobile robot according to claim 1 wherein the separator comprises the temperature control component.

3 . The mobile robot according to claim 1 wherein at least part of the separator is transparent.

4 . The mobile robot according to claim 1 wherein the temperature control component comprises a passive temperature control component.

5 . The mobile robot according to claim 1 wherein the temperature control component comprises an active temperature control component.

6 . The mobile robot according to claim 5 wherein the temperature control component comprises a Peltier element.

7 . The mobile robot according to claim 1 wherein the top section comprises a larger horizontal cross-section than the bottom section.

8 . The mobile robot according to claim 7 wherein the maximum substantially horizontal cross-section of the item compartment is at least a fourth larger than the minimum substantially horizontal cross-section of the item compartment.

9 . The mobile robot according to claim 1 wherein the item compartment comprises a removable compartment.

10 . The mobile robot of claim 9 , wherein the removable compartment comprises a basket configured to fit into the body of the mobile robot.

11 . The mobile robot according to claim 9 further configured to grant access to the item compartment to delivery recipients and wherein the mobile robot is configured to generate an alert upon detecting any consumable items remaining in the item compartment after granting access to the item compartment to delivery recipients.

12 . The mobile robot according to claim 1 further comprising at least one sensor configured to detect presence of the consumable items in at least one of the top section and the bottom section and wherein the sensor comprises at least one or a combination of:
a visual camera;
a thermographic camera;
a weight sensor;
a capacitive sensor; and/or
an infrared sensor.

13 . The mobile robot according to claim 1 wherein a temperature difference between the top section and the bottom section comprises at least 10° C.

14 . A method for delivering consumable items to delivery recipients using a mobile robot, the method comprising:
providing the mobile robot comprising a body comprising an item compartment, wherein the item compartment comprises a top section and a bottom section; placing at least one of a cooled consumable item and a temperature-neutral consumable item into the bottom section of the item compartment; placing a separator between the top section and the bottom section; placing a heated consumable item into the top section of the item compartment; the mobile robot travelling to a delivery location; and while traveling, using a temperature control component to maintain at least one of:
a temperature exceeding ambient temperature in the top section; and/or
a temperature below that of the top section in the bottom section.

15 . The method according to claim 14 further comprising notifying a delivery recipient that the separator should be removed to access the bottom section.

16 . The method according to claim 14 further comprising the mobile robot granting access to the consumable items after arriving to the delivery location.

17 . The method of claim 14 wherein the temperature control component is an active temperature control component and wherein the method further comprises actively controlling the temperature in at least one of the top section and the bottom section while travelling to the delivery location.

18 . The method according to claim 17 further comprising ceasing to actively control the temperature in at least one of the top section and the bottom section after delivering the consumable items.

19 . The method according to claim 18 further comprising detecting that the consumable items have been removed before stopping active temperature control.

20 . The method according to claim 14 further comprising notifying a delivery recipient after detecting that some consumable items remain in the item compartment.
