The block turns OFF all the RGB LEDs of Quarky.
The example demonstrates how to control the individual LEDs of the Quarky and run patterns using the loops.

Learn to move your Quarky Mecanum Wheel Robot in a square and make an axe figure with PictoBlox. Use the arrow keys to activate the custom movements and watch your robot move in the desired direction!
In this activity, we will create a custom activity where you will be able to move the Mecanum robot in a square effortlessly along with making an Axe type figure.
The Quarky Mecanum Wheel Robot is a type of robot that uses a special type of wheel to move. The wheel is made of four rollers mounted at 45- degree angles to the wheel’s hub. Each roller has its own motor and can spin in either direction. This allows the wheel to move in any direction, making it an ideal choice for navigating around obstacles.
Coding Steps
Follow the steps:
- Open a new project in PictoBlox and select Block Coding Environment.
- Connect Quarky to PictoBlox.
- Click on the Add Extension button and add the Quarky Mecanum extension.
- Now we will first initialize the Mecanum robots and the servos before starting the main code.
- Here there are two parts specifically : To make a Square and To make an Axe
To make a Square (Logic):
The main steps would include to display the lights in arrow forms before implementing the specific move. The moves would be implemented in the following order:
Forward -> Lateral Right -> Backward -> Lateral Left.
We will display the arrows with the help of Quarky LED’s and implement the code.
Example of arrow:
Code for Square Motion:
To make an Axe (Logic):
The main steps would include to display the lights in arrow forms before implementing the specific move. The moves would be implemented in the following order:
Forward ( 2 steps ) -> Lateral Left ( 1 step ) -> Backward Right ( 1 step ) -> Backward ( 1 step )
We will display the arrows with the help of Quarky LED’s and implement the code.
Code for Axe Motion
Main Code
Now we will keep a specific condition on when to activate the Square Motion and when to activate the Axe Motion.
We will use the if-else conditions where on pressing the “up” arrow key, we will initiate the Square Motion and on pressing the “down” arrow key, we will initiate the Axe Motion with the help of Mecanum Robot.
Final Output
Square Motion:
Axe Motion:

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!

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.
