Basic Arduino Autonomous Sumo Robot Tutorial

Basic Low Cost (<RM300) Arduino Autonomous Sumo Robot

This autonomous is suitable for standard autonomous sumo robot competition which use black color game field with white color boundary.

Components Required:
1. Arduino (UNO / Nano) x 1, Don't use Arduino Leonardo
2. Ultrasonic Sensor x 2
3. Line Following Sensor x 2
4. Motor x 2
5. Motor Driver x 1
6. Battery x 1
7. Jumper Wire (Female to Male) x 1
8. AWG 16 Wire (Red & Black) x 1m each
9. Dean Connector x 1
Total component cost: RM 279.10

Extra Component:
1. Charger x 1

Arduino Library Required:
1. New Ping Library (library for ultrasonic)

Wiring:
1. Solder dean connector to AWG 16 red & black wire (20cm)
2. Solder wire (red & black) to both motor.

Arduino Pin #	Connect to

Motor Driver Pin	Connect to
12V	BATTERY POSITIVE (+)
GND	BATTERY NEGATIVE (-)
OUT1	Left Motor (any side)
OUT2	Left Motor (another side)
OUT3	Right Motor (any side)
OUT4	Right Motor (another side)
IR Sensor Pin	Connect to
RED WIRE	5V from Arduino
GREEN WIRE	GND from Arduino / battery
YELLOW WIRE	A4 & A5 from Arduino

Programming:
Troubleshooting:
1. Check IR sensor for color detection. black (LED off) & white (LED on) by changing the sensitivity using potentiometer from IR sensor.
2. If ultrasonic cannot detect object, then increase the value of "MAX_DISTANCE" from Arduino line 3 & 4.
3. If motor run different direction, exchange connection from IN1 & IN2 (IN3 & IN4) jumper cable pin.

Note:
1. Don't overuse your LiPo battery until less than 11.1V.
