What is the Working Principle of Obstacle Avoiding Robot?

Obstacle avoiding Robot


It is way too hard to imagine our life without office software, laptop, tablets entertaining mobile apps, and browsers. Since we apply these tools almost every day, students need to understand the principles of their operation. It is a huge plus point if a person knows how to banish bugs from a computer and return it into a functional state. Similarly it is even harder to stay away from the subject “obstacle avoiding robot”.

Programming is completely a vague subject, especially for young minds and learners who need hands-on experience rather than abstract concepts. On the other hand, robots for kids are much more demonstrative and tangible, so it is easier to understand them. Through robotics, students can construct robots, track how to code adjustment, change their behavior, determine what works wrong, and correct mistakes. All of this and much more is taught to students while learning from an obstacle avoiding robot.

I bet young people will never get bored just because they will be constantly involved in work, designing, and analyzing how they perform commands. And one such interesting and amazing robot students are nowadays getting interested in creating is “Obstacle Avoiding Robot using Arduino.”

How Does the Obstacle Avoiding Robot Work?

The obstacle avoiding robot uses ultrasonic sensors to help the machine move. A microcontroller is used to complete the desired operation. The motors of the obstacle-avoiding robot are connected through the motor driver IC to the microcontroller. 

Whenever this obstacle avoiding robot is going on the desired path, the ultrasonic sensor transmits the ultrasonic waves continuously from its sensor head. So that whenever or if any obstacle comes its way, the object reflects ultrasonic waves. Soon the information is passed to the microcontroller, which is responsible for controlling the motors left, right, back, and front based on ultrasonic signals. 

Types of Sensors Used for Obstacle Avoiding Robot

Nowadays, many industries are using obstacle avoider robotic vehicle due to their high level of performance and reliability, which is a great help for human beings. Such kind of robotics is used for detecting obstacles and avoiding collisions. The design of such an obstacle avoidance robot needs the integration of many sensors.

Wondering how this obstacle avoider robotic vehicle works and what sensors are required to function accurately? Let’s take a look!

Obstacle Detection

The obstacle avoider robotic vehicle IR sensors are used for detecting obstacles for the obstacle avoiding robot, followed by the sensor output signal that further sends a signal to the microcontroller. The microcontroller controls the vehicle by using the DC motor which is placed in the vehicle. If any obstacle is placed inside the IR sensor, the microcontroller will stop the vehicle immediately, and the siren will go on. Then, just after a few minutes, the robot will immediately check the path status.

If an obstacle is removed, the robot then and there moves forward. Else it will return to the move starting place. The sensor provides a pulse as an output to the host that will terminate whenever the echo gets detected; hence the width of one pulse to the next is considered to provide results in a distance of the object.

Path Detection

The normal cause is both sensors of obstacle avoiding robot vehicle is giving the guidelines, and the robot follows it, going straight on the path. As soon as the end of the line, the robot reverses at 180 and turns back to the same place. But then why is the proximity sensor used for? Well, it is used for detecting the path. If the suitable sensor is not detected in the curve line, the microcontroller activates the left motor to turn left. Once the signal of an Arduino obstacle avoiding robot is detected, the motors are activated to move forward. When the line ends, the robot reverses at 180 and turns back to the same place.

The Ultrasonic Sensor

This sensor is only used to detect the obstacle and tends to transmit the ultrasonic waves from its sensor head. It then again receives the ultrasonic waves reflected from an object. This sensor is too compact and has a very high performance.


STEM lessons are important because it helps you to create obstacle avoiding robot

STEM lessons are essential for students as they prepare to enter the 21st-century workforce. Through Arduino obstacle-avoiding robots, students get to learn more than just “how to code.” Not just that, they are highly skilled in leadership, community involvement, communicating across different technology platforms, finding their passions, and teamwork, which will position them for success well beyond their school years. 

Learning robotics through the Stem activities for kids will facilitate laying the groundwork for a student’s future career. In addition, an obstacle avoiding robot kit for students offered by MySparklebox enables the development of technical & interpersonal skills they’ll require to influence the economy in the future.
