In this activity, we will make the computer program that controls the Mecanum Robot. It’s like a remote-control car. You can press different keys on the keyboard to make the Mecanum move forward, backward, left and right.

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 and tight spaces. The mecanum wheel robot can also turn on the spot, allowing it to make sharp turns without having to reverse direction.

Coding Steps

Follow the steps:

1. Open a new project in PictoBlox.
2. Connect Quarky to PictoBlox.
3. Click on the Add Extension button and add the Quarky Mecanum extension.
4. Now we will first initialize the Mecanum robots and the servos before starting the main code.
5. The main code will consist nested if-else conditions that will check specific conditions on which key is pressed, and will react accordingly. We will use the arrow keys for basic movements (Forward, Backward, Left Right) and the keys “a” for lateral left movement and “d” for lateral right movement.

Code

Output

Forward-Backward Motion:

Lateral Right-Left Motion:

Circular Right-Left Motion:

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:

1. Open a new project in PictoBlox and select Block Coding Environment.
2. Connect Quarky to PictoBlox.
3. Click on the Add Extension button and add the Quarky Mecanum extension.
4. Now we will first initialize the Mecanum robots and the servos before starting the main code.
5. 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:
