The basic concept around this bot revolves is the ease of interfacing sensors and drivers (motors, servos, etc). The basic ideea is that every sensor requires, at least in part, some sort of power and will provide in turn some sort of output, be it digital or analogue. This holds true for most outputs, be it DC motor, servo, relay etc, So the main control unit [MCU] will provide just that: minimum programming circuit and all IO pins are made available with power:
x x x
1 2 3
Where 1 is GND, 2 is Vdd and 3 is the IO pin interfaced.
I have attached the proposed schematic of BOT20M2. The PCB is inteded to replace the lid of a standard 81x53 mm jiffy box which can provide an inexpensive chasis.
