Abstract

A robotic system comprising a mobile robot including a body housing a rechargeable power source and first electrical contact means disposed on the body and a docking station including second electrical contact means, wherein the mobile robot is dockable on the docking station in order to charge the rechargeable power source. The first electrical contact means includes at least one electrical contact aligned on a first contact axis and the second electrical contact means includes at least one elongate contact, wherein when the robot is docked on the docking station such that electrical contact is established between the first electrical contact means and the electrical contact means. The at least one elongate contact extends in a direction that is transverse to the first contact axis which permits electrical contact to be established between the robot and the docking station whilst accommodating a degree of lateral and angular misalignment therebetween.

Claims

1. A robotic system comprising:

a mobile robot including a body housing a rechargeable power source and a first electrical contact part disposed on the body;

a docking station including a second electrical contact part, wherein the mobile robot is dockable on the docking station in order to charge the rechargeable power source;

wherein the first electrical contact part includes at least one electrical contact aligned on a first contact axis;

and wherein the second electrical contact part includes at least one elongate contact;

and wherein when the robot is docked on the docking station such that electrical contact is established between the first electrical contact part and the second electrical contact part, the at least one elongate contact extends in a direction that is transverse to the first contact axis.

2. The robotic system of claim 1, wherein the docking station includes a rear edge and wherein the at least one elongate contact extends in a direction that is aligned with the rear edge.

3. The robotic system of claim 1, wherein the electrical contacts associated with the docking station are resiliently mounted in the docking station.

4. The robotic system of claim 3, wherein the electrical contacts associated with the docking station are resiliently mounted in a base portion of the docking station so as to protrude at least partially therefrom in order to make a positive connection to the first and second energy receiving contacts of the robot.

5. The robotic system of claim 1, wherein the docking station includes an activation mechanism to control the second electrical contact part.

10. The robotic system of claim 1, wherein the at least one elongate contact is linear.

11. The robotic system of claim 1, wherein the at least one elongate contact is at least partly curved.

12. The robotic system of claim 1, wherein the docking station includes first and second electrical power input sockets.

13. The robotic system of claim 1, wherein the docking station includes a further electrical contact.

14. The robotic system of claim 1, wherein the pair of electrical power input sockets are provided on opposed sides of the docking station.

15. The robotic system of claim 1, wherein the first electrical contact part provided on the mobile robot includes a second electrical contact aligned with the first electrical contact along the first axis.

16. The robotic system of claim 1, wherein the first electrical contact part provided on the mobile robot includes a second electrical contact laterally offset from the first electric contact with respect to a longitudinal axis of the mobile robot.
