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

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

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
