GUI is a robot prototype made to be little, fast and easy to use and upgrade. It's your third demonstration, dead end recognition and reaction. In your up board (main board) it has a PIC MCU (PIC18F252) at 20MHz and a DC-DC boost converter (NCP1400-5V). The down board has a dual motor controller (TB6612FNG), 7 reflectance sensors (QTR-1RC), 2 Micro Gear Motor 30:1 and a 3.7V LiPo battery. The PIC is programmed with Tiny Bootloader, to easily change his main program. [This is a prototype. A new PCB going to be designed to increment some new feetures (like ZigBee or Nordic transceiver) and smd components (like a 18f452 TQFP).]
Good little bot !
