Electrical charging system for a robot

1. A docking station for charging a robot, comprising:

an electrical charger assembly disposed on a mount affixed to the docking station and configured to mate with an electrical charging port on the robot when the robot is docked at the docking station for charging; and

a plurality of compliant members interconnecting the electrical charger assembly to a portion of the docking station, each of the compliant members affixed at one end to the mount and at an opposite end to the docking station to suspend the electrical charger assembly to allow movement of the electrical charger assembly relative to the electrical charging port on the robot when the robot is mating with the docking station.

2. The docking station of claim 1 wherein the electrical charger assembly includes a charger base having at least one terminal member with an electrical contact configured to engage with the electrical charging port on the robot when the robot is docked at the docking station.

3. The docking station of claim 2 wherein the charger base is coupled to an electrical power source and the electrical charging port is coupled to a battery of the robot.

4. The docking station of claim 1 wherein the plurality of compliant members interconnecting the electrical charger assembly to a corresponding plurality of portions of the docking station allow movement of the electrical charger assembly in all six degrees of freedom.

5. The docking station of claim 1 further including a frame to which the plurality of compliant members are affixed on the docking station.

6. The docking station of claim 1 further including a restraining device interconnected to the frame of the docking station and the mount of the electrical charging assembly to limit movement of the electrical charging assembly during an un-mating process.

7. The docking station of claim 1 wherein each of the plurality of compliant members include a spring.
