This document provides information about the various components that make up a basic robot kit. It includes descriptions of the mainboard, DC motors, wheels, battery case, fiberboard frames, LEDs and buzzer, IR sensor board, push button switch, wires, frames, motor frame, supports, screws, and CPU parts. The mainboard contains the robot's CPU and circuitry. The DC motors can turn the wheels in forward or reverse directions. Various frames, boards, and fasteners connect the components together.

7. Mainboard Board
This circuit board contains
the “brains” of the robot. It
holds the CPU as well as
input, output, and power
circuitry.

8. DC motor
The motors on this robot
operate on direct current.
They can turn at set speeds
in either forward or reverse.

9. Wheels
The wheels we will use for the
first robot have rubber tires. Use
care when installing a wheel onto
the motor shaft. Align the
hexagon hole with the hexagon
shaft.

10. Battery case
if the robot will be stored
for long
periods of time, be sure
to remove the
batteries from the battery
case.

11. Fiberboard main frame
This is the largest of the
fiberboard frames. The
hole locations are
identified with numbers
and letters.

12. Fiberboard mid frame
The mid frame is the next
largest of the fiberboard
frames.

13. LED & Buzzer
There are three LEDs in kit#1— red, amber, and
green. The buzzer makes an annoying sound.

14. IR sensor board
This circuit board contains an
infrared emitter and receiver.
The emitter is the clear bulb and
the receiver is black in color.
There is a small cream-colored
capacitor between them.

15. Push button switch
This circuit board contains a push button switch.
When the button is pressed, the circuit is
completed or turned on. When released the
circuit is open or turned off

16. 3 pin Wire
The wires consist of three conductors — black,
red, and yellow. Be sure to install so that the black
wire connects on the pin with the white triangle.

17. L-frame
These metal frames are used
to connect various
components of the robot
together. They are in three
different sizes
based on the number of
holes – 2x6, 2x2,
and 2x1.

18. Motor frame
holes are threaded on this part; also the outer
surfaces are covered with dimples in the metal.

19. Support
Length of supports include
7mm, 20mm, and 35mm.
There is a scale on the lid
of kit #1 to measure
these. Length in mm does
not include the threaded
portion.

20. Self-tapping screw
This screw is used to connect a wheel to the
motor shaft. Do not over tighten.

21. Machine screw, Nut and Cap nut
This screw is used to connect a wheel to the
motor shaft. Do not over tighten.
