Introduction

A sign detector robotic arm is a smart robot that can recognize and understand signs or signals in its surroundings. It uses cameras and other sensors to capture visual information and computer algorithms to analyze the signs. The robot can learn different types of signs through machine learning techniques. Once a sign is identified, the robotic arm can perform specific actions based on what the sign means. These robotic arms have many uses, such as helping in healthcare, manufacturing, transportation, and assisting people with communication disabilities. They are an exciting advancement in human-robot interaction, allowing robots to understand and respond to signs, expanding their abilities and applications.

Code

Logic

1. Open the Pictoblox application.
2. Select the block-based environment.
3. Click on the Recognition Cards and robotic arm extension available in the left corner.
4. Initialize the video on stage and set the transparency as 0%.
5. Drag and drop the forever loop to continue to initialize the image from the stage, and get the input from the camera.
6. Show the bounding box around the sign detected from the stage.
7. If the signal is detected as ‘TurnRight’ then the arm will take a right turn 10 degrees Right in x direction using and move() in () x-axis in ()ms block.
8. If the signal is detected as ‘TurnLeft’ then it displays the arm will take a left turn using 10 degrees Left in x direction using and move() in () x-axis in ()ms block.
9. If the signal is detected as ‘Go’ and the arm will move 1o degree forward in y direction using a move() in () axis in ()ms block.
10. If the signal is detected as a ‘U Turn’ and the arm will move 1o degree back in y direction using a move() in () axis in ()ms block.
11. If it detects as “stop” the display then the arm will be at a home() position.
12. Press Green Flag to run the code.
