Simulating the Future: Autonomous Cleaning Robot with Ultrasonic Sensors and Arduino in Proteus

Summary

In this video, HF Electronet presents a simulation of an autonomous cleaning robot equipped with three ultrasonic sensors. The robot detects obstacles in front of it using sensors and makes decisions on whether to turn left or right based on distance measurements. It uses motors for forward and rotational movement and includes an LCD to display system statuses. The code for this simulation is explained step by step, including how to upload it, compile, and run the robot's movements. Viewers are invited to download the code from a provided Google Drive link.

Takeaways

• 🤖 The video introduces an autonomous cleaning robot equipped with three ultrasonic sensors for navigation.
• 🔄 The robot follows a predefined movement pattern and stops when it detects an obstacle using the front ultrasonic sensor.
• 🎯 If an obstacle is detected, the robot compares distances on the left and right sides using two additional ultrasonic sensors.
• ↪️ Based on the comparison, the robot decides whether to turn left or right to avoid the obstacle.
• ⚙️ The robot uses motors for left, right, and forward movements, which are controlled based on sensor inputs.
• 🖥️ An LCD display is connected to the robot to show status updates, such as when it stops or moves.
• 📐 The threshold for obstacle detection is set at 100 cm, and the robot takes actions based on this distance.
• 🖥️ The video includes a demo of the robot's movement, explaining how its code controls different behaviors like turning and moving backward.
• 💾 The robot's code is available for download through a Google Drive link, allowing users to test the simulation on their own.
• 🔧 The video also provides instructions on how to compile and upload the code into the robot for proper functioning.

Q & A

What type of robot is being demonstrated in the video?

The video demonstrates an autonomous cleaning robot equipped with sensors to detect obstacles and make movement decisions accordingly.

What kind of sensors are used in the cleaning robot?

The robot is equipped with three ultrasonic sensors—one at the front and two on the sides (left and right) to detect distance from objects.

How does the robot decide its direction when an obstacle is detected?

When an obstacle is detected by the front ultrasonic sensor, the robot compares the distances measured by the left and right sensors. It rotates toward the side with a greater distance from the obstacle.

What happens when the robot detects an obstacle directly in front of it?

If the robot detects an obstacle in front of it, it stops, prints 'STOP' on its LCD, moves backward slightly, and then decides whether to turn left or right based on sensor readings.

How does the robot control its movement?

The robot controls its movement using motors that enable forward, left, and right movements. The motors are programmed based on the sensor readings.

What role does the LCD play in the robot’s operation?

The LCD, connected via an I2C converter, displays messages such as 'STOP' when the robot detects an obstacle, providing real-time feedback about its status.

How does the robot handle changes in its environment?

The robot continually monitors its surroundings using the ultrasonic sensors. As it moves and detects new distances, it adjusts its direction by comparing the sensor data to make sure it avoids obstacles.

What software or coding language is used to control the robot?

The robot is controlled through code written for its microcontroller, which can be uploaded and compiled as a hex file. The specific coding language is not mentioned, but it's likely Arduino or C/C++.

What is the purpose of the ultrasonic sensors in the robot?

The ultrasonic sensors measure the distance between the robot and nearby obstacles, helping it decide when to stop, move backward, or rotate to avoid collisions.

Can viewers access the code used for the robot’s operation?

Yes, the code for the robot is made available via a Google Drive link, which the presenter mentions will be shared for download.
