AVR1 SUPER SUMO ROBOT
CODE 1109
This super sumo can be controlled to attack or retreat and
ready for battle with opponent. This robot is using the AVR
microcontroller, so the user can re-program into IC for getting
new applications.

Technical Specifications:

- Power supply : 2 AA batteries (not included).
- Consumption : 80mA.
- PCB dimensions : 2.54 x 1.18 in. (sensor board)
2.54 x 2.70 in. (control board)

(1) ROBOT CONTROL CIRCUIT

How To Work:

The circuit is composed of 2 major parts, sensor board and
control board, as shown in Fig. 1.
Sensor board have 3 sets, in set as transmitter and receiver
of infrared light. Transmitter part is consist TR4 and LED
INF. VR4 is used for adjust the level of infrared light. Receiver
part, when photo-transistor received infrared light from LED
INF, causing voltage being passed through. The more reflected
light will lessen the internal resistance and give bigger passing
through voltage. Less reflected light will enlarge the internal
resistance and give less passing through voltage. TR1 to TR3
will work when the photo-transistor received infrared light.
Control board, at the heart of the circuit is the AVR
microcontroller IC1. When below photo-transistor is not
receiving infrared light (white ground), TR1 to TR3 are not
working. IC1 will send the voltage to pin 12 and pin 15,
causing both motor is running forward. If some below photo-
transistor received infrared light (black ground), motor is
running backward. For center sensor, when sensor detects the
HIGH QUALITY ELECTRONIC KIT SET FOR HOBBY & EDUCATION
object, IC1 will send the voltage pin 9 and pin 14, causing
motor is rotate faster. IDE port is used for connect AVR
programmer.

Circuit Assembling:

The PCB will be divided into two boards, AVR1-1 for
circuit controlling and Body set for body, motor gear, wheel
and battery holder assembling.
The AVR1-1 circuit assembling has been shown in Fig 2. It
is recommended to assemble the circuit starting with a less
height component i.e. diodes, resistor, electrolytic capacitors
and transistors etc. Be careful while assembling and check for
the matching of PCB poles and components before soldering as
shown in Fig 3. For IDE port, press the pin of IDE port to be
level with the black plastic before soldering. Use a max. 40W
solder and soldering tin with a tin and lead ratio of 60/40
together with a joint solution inside. Recheck the assembled
circuit for your own confidence. Better use a lead sucker or a
lead wire absorber in case of component misplacing to protect
PCB from damage.
The Body set is to be assembled as shown in the next page.

Testing:

When the two circuit boards have been completely
assembled. Insert four AA batteries into the battery holder.
Then adjust VR1 to VR4 to the middle side and slide switch
SW to "on" position. LED at sensor board is lighted on. Lay
down the assembled robot on the test paper. Robot is running
inside the black frame. The robot will backward and turn
when below sensor detecting the black line. But front sensor
detects the any object, the robot will run forward and running
up the speed to bump.
VR1 to VR3 will act as sensitivity of photo-transistor.
Adjust the left hand side for decreasing sensitivity and to the
right hand side for increasing sensitivity. VR4 will act as level
of infrared light.
SW1 is used for set the speed of robot. When you want to
setting the speed, slide switch SW to "off" position then push
and hold SW1. Slide SW to "on" position. Seeing LED at
control board. LED will chasing step by step. LED1 is slowly
speed and LED4 is higher speed.

Troubleshooting:

As the circuit has only a few components, the main
cause of troubles will come from component
misplacing and defaulted soldering. When found out
that the circuit does not work, check for the proper
component placings and various soldering points.
