DIY Ardubot - 3D Printed Autonomus Arduino Robot
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
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 )
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:
