Introduction: DIY Ardubot - 3D Printed Autonomus Arduino Robot

By

Simple to build Arduino Nano robot with 4 working modes

Supplies

  • Arduino Nano
  • Small servo 9g 3pcs
  • Utrasonic sensor HC-SR04
  • Infrared receiver module
  • Speaker
  • 220R resistor

Step 1: Description

Home made robot partially 3D printed. .It is based on arduino nano board, servos, ultrasonic sensor and LDR resistors.

It has 4 modes:

- Manual control by IR remote ( forward, backward, right and left)

- Autonomous mode ( ArduBot navigates to avoiding obstacles and choosing the best way.)

- Monitor mode ( ArduBot is monitorng objects in front of the ultrasonic sensor. )

- Line tracking mode (I added this mode to the original design )

Step 2: Building, Schematic, and Code

The left and right servo motors need to be modified for continuous rotation. You can find instructions for this modification in several places, and I used Adafruit's tutorial:
