How To Make Obstacle Avoiding Robot Using Arduino?

Creating your own obstacle avoiding robot is a fun and rewarding project that can introduce you to the world of robotics and programming. In this tutorial, we will show you how to make an obstacle avoiding robot using an Arduino board, a motor shield, ultrasonic sensors, and a few other components.

Step 1: Gather your materials

To make an obstacle avoiding robot, you will need the following materials:

– Arduino board (we will be using an Arduino Uno)
– Motor Shield (we will be using the L293D motor shield)
– Ultrasonic sensors (we will be using two HC-SR04 sensors)
– DC motors with wheels (we will be using two geared motors)
– Battery pack (we will be using a 9V battery pack)
– Jumper wires
– Breadboard
– Chassis (optional)

Step 2: Assemble the base of the robot

If you are using a chassis, follow the instructions provided with it to assemble the base of your robot. Otherwise, you can make your own base using a sturdy material such as cardboard or plastic.

Step 3: Connect the motors to the motor shield

The L293D motor shield is a convenient way to control the motors of your robot. It can be easily connected to an Arduino board, and each channel can control one DC motor. In our project, we will be using two motors, so we will connect them to the two channels of the motor shield.

Take the two geared motors and connect them to the two channels of the motor shield. Make sure that the polarity is correct, and the motors are securely connected.

Step 4: Connect the motor shield to the Arduino board

Now we will connect the motor shield to the Arduino board. Place the motor shield on top of the Arduino board, aligning the pins on the motor shield with the pins on the Arduino board. Make sure the motor shield is securely attached.

Step 5: Connect the ultrasonic sensors

The HC-SR04 ultrasonic sensors are used to detect obstacles. We will be using two sensors, one facing front and one facing back. This will allow our robot to detect obstacles in front of it and behind it.

To connect the sensors, take four jumper wires and connect one to the VCC pin, one to the GND pin, one to the TRIG pin, and one to the ECHO pin. Connect the VCC and GND pins to the 5V and GND pins on the Arduino board, respectively. Connect the TRIG and ECHO pins to any available pins on the Arduino, as we will need to define these pins in our code later on.

Step 6: Add power to the robot

To power our robot, we will be using a 9V battery pack. Connect the positive (red) wire to the VIN pin on the motor shield, and the negative (black) wire to the GND pin on the motor shield.

Step 7: Write the code

Now it’s time to write the code for our obstacle avoiding robot. We will be using the Arduino IDE, which can be downloaded for free from the Arduino website.

We have provided the code for our obstacle avoiding robot here: LINK. You can copy and paste this code into the Arduino IDE.

Before uploading the code to your Arduino board, make sure you have selected the correct board and port in the tools menu.
