BOE-BOT By: Jonathan Baker Gabby Garcia

BOE-BOT Servo motors to control each wheel independently Castor wheel in rear for stability Aluminum Chassis BASIC Stamp 2 microcontroller SayIt Module IR Sensors Runs off 4 AA batteries Front view of BOE-BOTRear view of BOE-BOT

BASIC Stamp 2 BASIC Stamp 2 is a 24-pin DIP 20 MHz processor speed 32 Bytes of RAM BASIC Stamp 2 Editor used to write and compile program PBASIC is language used for programming USB to serial adapter used to transfer code to robot

SayIt Module Parallax voice recognition 10-pin SIP module 32 speaker dependent (SD) commands SayIt GUI serves as interface for programming the user definable commands Front view of SayIt moduleRear view of SayIt module

SayIt Module GUI Trigger is used to make BOE- Bot listen for a command Group 1 – 15 are SD Wordset 1 – 3 are SI Speaker Dependent Speaker Independent

Infrared Detectors 4 pairs of IR detectors IR LEDs emit signal at 940 nm at a rate of 38.5 kHz Frequency of signal is specified in the code IR receivers have electronic filter that only allows signals with this frequency IR Detector Circuit

Infrared Detector Heat shrink used as shields to focus the IR signal For near sighted robot use larger resistor value to decrease current Opposite for a far sighted robot Actual IR Detector Circuit
