Here is a photo of a prototype docking station that I have completed.
The pogo pins on the ArloBot docking probe contact the middle of the brass strips on the docking plate.
The docking plate is spring loaded and can move horizontally to allow for horizontal play between the ArloBot docking probe and the docking station.
The pogo pins on the docking probe can move 1/4 inch horizontally which will allow for slight off angle contact between the ArloBot docking probe and the contact plate on the docking station.
The black looking tube above the docking plate is the IR Transmitter IR LED that is encased in shrink sleeving to help narrow the IR beam.
