It
consists of:
aluminum frame from an aluminum scrap bin
a bus sign motor with
gearbox
front wheels are for a R/C
plane, controled with a servo
2 6V sealed lead acid
batteries, 5 A-hr
5A circuit breaker
LM2825N-5.0 switching power
supply on a chip, 1A
Devantech SRF04 ultrasonic
sensor mounted on a servo
Devantech digital compass
2 Sharp GP2D02 infrared
sensors.
motor controller - an Atmel
89c2051 is programmed to receive commands from
the main controller and generate the apropriate
signals (PWM and direction) for the H-bridge
module (National Semiconductor LMD18200)
24X2 Vacuumm Fluorecent
Display & controller board
with 9600 baud serial input
front bumper - a piece of
wood attached to 2 spring-loaded pins from a
bi-fold closet door. Pressing on the bumper releases
pressure on microswitches behind it.
Sound module - plays a variety of recorded comments and sound effects. This module can be connected to the serial port of a microcontroller or a computer running a terminal program. The output can connect to any amplifier. To record, a cable connects output out a computers sound card to a connector on the module.
- ISD5116 sound recorder chip. Stores up to 8 minutes of sound. Each sound is directly adressable.
- a PIC 16F88 programmed with a easy to use command set.
- pre-amplifier on the input
-
amplifier from a set of computer speakers
