Arduino obstacle avoiding robot has two HCSR04 ultrasonic sensors for obstacle detection.

Arduino Uno R3 is used as the controller board of the obstacle avoider robot.

The Arduino shield on the robot is designed by RobotikSistem. It includes; on/off switch, input/output headers, L293D motor driver, buzzer and LEDs.

The robot has two infrared sensors for detection of objects during moving. The sensitivities of the sensors may be tuned.

Robot chassis is prepared with 3 mm thick plexiglass material.

The robot has two 6 V 100 rpm geared DC motors, two wheels and a caster ball wheel.

Arduino obstacle avoider robot is powered by a 9 V alkaline battery.
