Step 1:

To build a charging station, I used a 6" x 18" piece of aluminum, 6" of 1/4" diameter aluminum rod, three 1/4" x 2 1/2" x .016" springs, two 7/16" x 8 1/2" x .047" springs, a 9 volt dc power supply, 2" wide aluminum duct tape (16 inches) and misc. connectors and hardware.

Add tape to the bottom of the robot.

Step 2:

Create a connector to attach to the tape. Note that the tape only conducts on the non-sticky side, therefore each piece of tape must be electrically connected to the circuit.

Step 3:

Drill holes in the rod and press fit the rods into the holders.

Step 4:

Attach the brackets to the robot.

Step 5:

Wire the robot as shown in the schematic. I used a prototype board to make connections more easily.

Step 6:

Add the spring holder (3D printed) and springs. Attach the two springs in the center by soldering bare copper wire between them. Drill holes three inches apart (slightly smaller than the spring) and place the small springs (cut into 1 1/4" pieces) into the holes. Attach the dc power supply, positive to the upper springs and negative to the base plate.

can this be replaced to a wireless charger of sort(contact less)?

Yes, but that adds complexity on driving in and aligning parts and probably increases the cost

Finally a robot that obey all three of Mark Tilden's laws:

Protect thine ass

feed thine ass

look for better real estate

Robots until now have had a hard time feeding themselves.

Brilliant... Why didn't I think of that idea
