	==RegBot integration==		==RegBot integration==
			In order for Raspberry Pi to run and communicate with the RegBot it needs to be connected via the jumper-wires.

			The Raspberry Pi pins is located as the figure shows:

			[[File:pi_pinout.PNG\|300px]]

			An overview of the RegBot's PCB is:

			[[File:Component-drawing.png\|500px]]

			Use '''Pin 2''' and '''Pin 6''' to supply power:

			* Connect Pin 2 to RegBot ?
			* Connect Pin 6 to RegBot ?

			Use '''Pin 8''', '''Pin 10''' and '''Pin 14''' for serial communication back and forth to the RegBot:

			* Connect Pin 8 to RegBot UART pin 4.
			* Connect Pin 10 to RegBot UART pin 5.
			* Connect Pin 14 to RegBot UART pin 1.

			Turn on the system, and the Raspberry Pi should now be connected through the RegBot and all communications to the RegBot is now wireless through the Raspberry Pi's Line Follower application via SSH.

			However when uploading to RegBot a wired USB connection to the Teensy board is still needed.
