Sign Detection with Mars Rover

Learn how to code logic for video input detection with this example block code. You will be able to direct your own Mars Rover easily by just showing signs through the camera input.

Introduction

A sign detector Mars Rover robot is a robot that can recognize and interpret certain signs or signals, such as hand gestures or verbal commands, given by a human. The robot uses sensors, cameras, and machine learning algorithms to detect and understand the sign, and then performs a corresponding action based on the signal detected.

These robots are often used in manufacturing, healthcare, and customer service industries to assist with tasks that require human-like interaction and decision making.

Code

Initializing the Functions:

Main Code

Logic

Firstly, the code sets up the stage camera to look for signs and detects and recognizes the signs showed on the camera.
Next, the code starts a loop where the stage camera continuously checks for the signs.
Finally, if the robot sees certain signs (like ‘Go’, ‘Turn Left’, ‘Turn Right’, or ‘U Turn’), it moves in a certain direction (forward, backward, left, or backward) based on the respective signs.
This can help the Mars Rover to manoeuvre through the terrain easily by just showing signs on the camera.

Output

Forward-Backward Motions:

Right-Left Motions:

Sign Detection Controlled Mecanum

Learn how to code logic for video input detection with this example block code. You will be able to direct your own Mecanum easily by just showing signs through the camera input.

Introduction

A sign detector Mecanum robot is a robot that can recognize and interpret certain signs or signals, such as hand gestures or verbal commands, given by a human. The robot uses sensors, cameras, and machine learning algorithms to detect and understand the sign, and then performs a corresponding action based on the signal detected.

These robots are often used in manufacturing, healthcare, and customer service industries to assist with tasks that require human-like interaction and decision making.

Sign Detection with Quadruped

Learn how to set the bounding box threshold, and detect signals such as 'Go', 'TurnRight', 'TurnLeft', and 'Stop' to control quadruped movements.

Introduction

A sign detector Quadruped robot is a robot that can recognize and interpret certain signs or signals, such as hand gestures or verbal commands, given by a human. The robot uses sensors, cameras, and machine learning algorithms to detect and understand the sign, and then performs a corresponding action based on the signal detected.

These robots are often used in manufacturing, healthcare, and customer service industries to assist with tasks that require human-like interaction and decision-making.

Code

Logic

Then, it sets up the quadruped robot’s camera to look for hand signs and tells it how to recognize different signs.
Next, the code starts a loop where the robot looks for hand signs. If it sees a sign, it says the name of the sign out loud.
Finally, if the robot sees certain signs (like ‘Go’, ‘Turn Left’, ‘Turn Right’, or ‘U Turn’), it moves in a certain direction (forward, backward, left, or backward) based on the sign it sees.
So, this code helps a robot understand hand signs and move in response to them!

Sign Detection With Humanoid

Learn how to code logic for video input detection .set the bounding box threshold, and detect signals to control Humanoid movements.

Introduction

A sign detector Humanoid robot is a robot that can recognize and interpret certain signs or signals, such as hand gestures or verbal commands, given by a human. The robot uses sensors, cameras, and machine learning algorithms to detect and understand the sign, and then performs a corresponding action based on the signal detected.

These robots are often used in manufacturing, healthcare, and customer service industries to assist with tasks that require human-like interaction and decision-making.

Code

Logic

Initialise the video on stage and set the transparency as 0%
Show the bounding box and set its threshold to 0.8.
Get the input from the camera forever.
If the signal is detected as ‘Go’ then it displays an ‘up arrow’, sounds go straight and the Humanoid will move 2 steps forward at high speed using do () motion () times at () speed block.
If the signal is detected as ‘TurnRight’ then it displays a ‘right arrow’, sounds Turn right and Humanoid will take a right turn at high speed using do () motion () times at () speed block.
If the signal is detected as ‘TurnLeft’ then it displays a ‘Left arrow’, sounds Turn Left and Humanoid will take a left turn at high speed using do () motion () times at () speed block.
If it detects as stop the display will be cleared in the quirky and the humanoid will be at a home() posture.
