Method and device for accommodating items

1. An autonomous mobile robot at least including an arm member for gathering items and transporting them to a designated area, comprising:

a drive system configured to autonomously move the mobile robot within a designated area;

a first security system configured to autonomously secure a gathered item against unauthorized access while the item is in possession of the mobile robot;

an arm member for autonomously grasping at least one item from a first location within the designated area, transporting the item to a position on the mobile robot for securing by the first security system to prevent unauthorized access while the item is in possession of the mobile robot and for transporting the item from the position on the mobile robot to a second location within the designated area;

a second security system at the second location configured to autonomously secure the item against unauthorized access while the item is at the second location; and

a control system for autonomously moving the mobile robot via the drive system to a position proximate the first location so that the arm member can reach a desired item, activating the arm member to grasp and transport the item to a position on the mobile robot, securing the item against unauthorized access while the item is in possession of the mobile robot via the first security system, moving the mobile robot via the drive system to a position proximate the second location within the designated area so that the arm member can reach the second location, grasping the item on the mobile robot, releasing the item from the control of the first security system, moving the item via the arm member to the second location, autonomously communicating at least one signal between the mobile robot and the second security system at the second location, the at least one signal communicating at least one security criteria between the mobile robot and the second security system in order to enable transferring of the item from the mobile robot to the second location, releasing the item from the grasp of the arm member, and securing the item at the second location via the second security system.

2. The mobile robot as defined in claim 1 , wherein the item is a container, the container having at least one item to be transported from the first location to the second location.

3. The mobile robot as defined in claim 1 , wherein the item transported by the mobile robot includes a first at least partially depleted power source attached to the mobile robot for providing power to the mobile robot and the control system autonomously moves the mobile robot via the drive system to a position proximate the second location so that the arm member can reach a second substantially charged power source, activates the first security system to release control of the first power source, activates the arm member to grasp and transport the first power source from the mobile robot to the second location, activates the second security system to enable transferring of the first and second power sources and secure the first power source at the second location from unauthorized access, activates the arm member to grasp the second charged power source and move it to the position on the mobile robot previously occupied by the first power source to provide power to the mobile robot and activates the first security system to secure the second power source from unauthorized access.

4. The mobile robot as defined in claim 1 , where the item is randomly arranged at the first location and the control system operates to enable the arm member to grasp the item regardless of its orientation.

5. The mobile robot as defined in claim 1 , wherein there are a plurality of items randomly arranged at the first location and the control system operates to enable the arm member to grasp at least one of the items regardless of its orientation.
