Fistly i bought the robot kit from roboworld.com.sg
More info on this kit:
A dynamic learning platform! Pre-programmed for quick
enjoyment, and comes with instructions for custom
applications. Customizable, no soldering required. Learn
basic skills toward advanced robot building.
This incredibly simple-to-build robot will provide you
with hours of enjoyment and a great platform on which to
develop more sophisticated applications. The 9-volt
battery-powered robot (battery not included) is
driven by dual electric motors and controlled by a
Microchip PIC16C505 PICmicro Microcontroller.
With two light sensors and infra-red collision detectors
the robot is pre-programmed with the
following behaviors built in:
Random Movement change forward direction when an object is
encountered
Photovore seek out light
Photophobe avoid light
Maze Solver follow wall
These behaviors can be selected along with the
ability to manually control the operation of the robot by
the infra-red remote control included in the kit (two AAA
batteries required). With the addition of a BASIC STAMP BS2
Microcontroller (not included in the kit) customized
applications can easily be built. [BUT I SELL IT TOGETHER WITH THIS
KIT]
All of the software code for the Basic Stamp applications
is included on the accompanying CD-ROM along
with illustrated assembly instructions, many schematic.
Block diagrams and over 100 pages of robot building
basics are taken from the best-selling Robot Builders
Bonanza, 2nd edition, by Gordon McComb.
Thanks all.
