What Is the Working Principle of an 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 behaviour, determine what works wrong, and correct mistakes. Young people never get bored if they are constantly working, designing, and analyzing how a robot performs commands. And one such interesting robot that students are nowadays interested in is an “Obstacle Avoiding Robot.”
Nowadays, many industries are using robots due to their high performance and reliability, which is a great help for human beings. In addition, many schools have added robotics for kids into the curriculum for better understandings of new techniques and concepts. Such kind of robotics detects obstacles and avoids collisions, and in the design of such an obstacle avoidance robot, you need an integration of many sensors.
Wondering what sensors obstacle avoiding robot requires to function accurately? Read on to know.
What is an Obstacle Avoiding Robot?
An Obstacle avoiding robot is an intervention of science in which the robot can avoid obstacles by using ultrasound sensors and innervate its own path. The obstacle avoiding code is being used in these robots.
Advantages of Obstacle Avoiding Robot:
- These Robots are easy and quick to compute.
- These are not affected by the noise in the surrounding.
- These can easily detect the object at a distance.
- These can easily detect the edges and their respective orientation.
How Does an Obstacle Avoiding Robot Work?
The obstacle avoiding robot uses ultrasonic sensors to help the machine move. A microcontroller completes the desired operation. The motor driver IC connects the motors of the robot 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. The sensor head passes this information 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 Vehicle
1. Obstacle Detection in Robots
The IR sensors in the obstacle avoiding robot detect obstructions, followed by the sensor output signal that further sends a signal to the microcontroller. The microcontroller controls the vehicle by using the DC motor in the vehicle. If you place any obstacle 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 there is no longer an obstacle, the robot 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 microcontroller detects an echo. Hence you can consider the width of one pulse to the next to know the object’s distance.
2. Path Detection in Obstacle Avoiding Robot
In normal cases, both sensors give the guidelines, and the robot follows them, going straight on the path. At the end of the line, the robot reverses at 180 and turns back to the same place.
But then why do we use the proximity sensor? Well, we need it for detecting the path. If the microcontroller can’t detect a suitable sensor in the curve line, it activates the left motor to turn left. Once it detects the signal of the robot, it activates the motors to move forward. When the line ends, the robot reverses at 180 and turns back to the same place.
3. The Ultrasonic Sensor in Obstacle Avoiding Robot
The Ultrasonic Sensor detects the obstacle and transmits the ultrasonic waves from its sensor head. It also receives the ultrasonic waves reflected from an object. The Ultrasonic Sensor is compact and has a very high performance.
STEM lessons are essential for students as they prepare to enter the 21st-century workforce. Students get to learn more than just “how to code” Through obstacle avoiding robot code. Children who excel in robotics are highly skilled in leadership, community involvement, communication across different technology platforms, finding their passions, and teamwork. Students with these skills find success well beyond their school years.
Learning robotics through STEM activities for kids will facilitate laying the groundwork for a student’s future career. In addition, a Robotics kit for students offered by SPARKLEBOX enables the development of technical & interpersonal skills they’ll require to influence the economy in the future. These activities will help your child develop an interest in the new trends and techniques introduced into the market.
