How to make DIY Edge Avoiding Robot

 

Are you are a Robotics Lover?

Robotics is an interdisciplinary sector of science and engineering dedicated to the design, construction and use of mechanical robots. Our guide will give you a concrete grasp of robotics, including different types of robots and how they're being applied across industries.

 

 

What is a Robot?

 

A robot is the product of the robotics field, where programmable machines are built that can assist humans or mimic human actions. Robots were originally built to handle monotonous tasks (like building cars on an assembly line), but have since expanded well beyond their initial uses to perform tasks like fighting fires, cleaning homes and assisting with incredibly intricate surgeries. Each robot has a differing level of autonomy, ranging from human-controlled bots that carry out tasks that a human has full control over to fully-autonomous bots that perform tasks without any external influences.

 

 

  

 

What is Edge Avoider Robot?

This Arduino Uno based robot detects an edge and avoids it by turning or stopping.

It is a type of Robot which can detect edges and the move backwards.

When there is any edge the IR sensor detects it and sends information to the Arduino to move robot backwards.

If you can move it forward and there is any edge, it will move backwards automatically.

Then you are in right Blog.

In this Blog I'll show you How to make Edge Avoiding Robot easily.

IR sensor pic:-

Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver.
