Abstract

A battery configured to be attached to a battery holder for use by a mobile robot comprising: a battery body encapsulating the battery; at least two electrical connectors protruding from the battery body; at least one fixing unit located on the battery body said fixing unit configured to fix the battery to the battery holder; at least two damping pins protruding from the battery body; and at least one battery communication component configured to transmit battery status data. A battery holder configured to hold the battery and at least one of storing, swapping and charging a battery.

First claim

We claim:

1. A battery configured to be attached to a battery holder, said battery for use by a mobile robot, the battery comprising:
(a) a battery body encapsulating the battery;
(b) at least two electrical connectors protruding from the battery body;
(c) at least one fixing unit located on the battery body, said at least one fixing unit configured to fix the battery to the battery holder, wherein the at least one fixing unit comprises a sliding latch configured to move along the battery body between a closed position and an open position and wherein
(c1) the at least one fixing unit positioned in the closed position is configured to extend into the battery holder to latch the battery to the battery holder; and
(c2) the at least one fixing unit positioned in the open position is configured to unlatch the battery from the battery holder;

(d) at least two damping pins protruding from the battery body comprising a distal top and a proximal base, said proximal base located closer to the battery body than to the distal top, wherein a minimum bounding circle of the proximal base is larger than a minimum bounding circle of the distal top, wherein at least one of the at least two damping pins is cone shaped; and
(e) at least one battery communication component configured to at least transmit battery status data.

2. The battery according to claim 1 , wherein the at least two electrical connectors comprise at least one electrical pin protruding from the battery body with a height in the range of 1 to 30 mm.

3. The battery according to claim 1 , wherein the at least two damping pins comprise at least one protruding metallic element protruding from the battery body.

4. The battery according to claim 1 , wherein the at least two damping pins comprise at least one truncated cone shaped protruding metallic element comprising a base diameter and a height in the range of 2 to 30 mm.

5. The battery according to claim 1 , wherein the at least two damping pins are placed at different locations of a surface of the battery body and wherein the at least two damping pins are positioned adjacent to the electrical connectors.

6. The battery according to claim 1 , wherein the battery comprises at least two fixing units, located on the battery body.

7. The battery according to claim 1 , wherein the battery comprises 2 to 4 fixing units located on side surfaces of the battery body.

8. The battery according to claim 1 , wherein the battery communication component comprises at least one electromagnetic wave transmitter and/or receiver, configured to at least one of transmitting and receiving signals comprising information related to status of the battery.

9. The battery according to claim 8 , wherein the battery communication component comprises at least one infrared sensor.

10. The battery according to claim 1 , wherein the battery communication component is configured to repeatedly transmit at least one stream of data, indicating at least one of:
(a) current energy level of the battery, and/or
(b) last n energy levels of the battery, n being a programmable parameter, and/or
(c) ID of the battery.

11. The battery according to claim 1 , wherein the battery further comprises a battery case.

12. The battery according to claim 11 , wherein at least one of the following elements of the battery are positioned in the battery case:
(a) the at least one fixing unit, and/or
(b) at least one damping pin, and/or
(c) the at least one battery communication component.

13. The battery according to claim 11 , wherein the battery case is configured as a battery case adapter configured to facilitate the use of a robot battery, different from the battery, as a battery.

14. A battery holder configured to hold the battery of claim 1 .

15. The battery holder according to claim 14 , wherein the battery holder further comprises a plurality of pin insertion places and wherein the at least two damping pins are configured to fit in the pin insertion places.

16. The battery holder according to claim 14 , wherein the battery holder comprises at least one fixing element, wherein the at least one fixing element comprises an elongated part protruding from the battery holder, and wherein:
(a) the at least one fixing unit positioned in a closed position is configured to slide past the at least one fixing element to fix the battery in the battery holder; and
(b) the at least one fixing unit is configured to unlatch the battery from the at least one fixing element of the battery holder.

17. A system configured to at least one of storing, swapping and charging a battery, the system comprising:
(a) at least one battery according to claim 1 ;
(b) at least one mobile robot comprising at least one robot battery holder according to claim 14 , said robot configured to use the at least one battery as an electrical power source; and
(c) at least one battery station comprising at least one station battery holder according to claim 14 , said battery station configured to perform at least one of the following:
(i) store the at least one battery of the at least one mobile robot, and/or
(ii) charge the at least one battery of the at least one mobile robot, and/or
(iii) swap the at least one battery of the at least one mobile robot with another battery.

18. The system according to claim 17 , wherein the mobile robot comprises a robot communication component configured to facilitate at least one of transmitting and receiving of the battery status data between the mobile robot and the battery.

19. The system according to claim 17 , wherein the battery station comprises a station battery holder communication component configured to facilitate at least one of transmitting and receiving of battery status data between the battery station and the battery.
