Commanding Trilobot using PyQt GUI

Posted by


Controlling a Trilobot using a PyQt GUI can be a fun and interesting project to work on. Trilobot is a programmable robot that can be controlled wirelessly using a GUI. In this tutorial, we will go through the steps required to set up a PyQt GUI to control a Trilobot.

Step 1: Install PyQt

First, you need to install PyQt on your machine. PyQt is a set of Python bindings for the Qt application framework. You can install PyQt using pip by running the following command:

pip install pyqt5

Step 2: Setting up the Trilobot

Before we can start controlling the Trilobot using a GUI, we need to set up the hardware and software for the robotic platform. Follow the instructions provided by the manufacturer to assemble the Trilobot and install any necessary software libraries.

Step 3: Create the PyQt GUI

Now, we can start creating the PyQt GUI for controlling the Trilobot. Create a new Python script and import the necessary modules:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton

Next, create a new class that inherits from the QWidget class:

class TrilobotControl(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.setGeometry(100, 100, 300, 200)
        self.setWindowTitle('Trilobot Control')

        btn_forward = QPushButton('Forward', self)
        btn_forward.move(100, 50)

        btn_backward = QPushButton('Backward', self)
        btn_backward.move(100, 100)

        btn_left = QPushButton('Left', self)
        btn_left.move(50, 75)

        btn_right = QPushButton('Right', self)
        btn_right.move(150, 75)

        btn_forward.clicked.connect(self.move_forward)
        btn_backward.clicked.connect(self.move_backward)
        btn_left.clicked.connect(self.turn_left)
        btn_right.clicked.connect(self.turn_right)

    def move_forward(self):
        # Code to move the Trilobot forward

    def move_backward(self):
        # Code to move the Trilobot backward

    def turn_left(self):
        # Code to turn the Trilobot left

    def turn_right(self):
        # Code to turn the Trilobot right

In this code snippet, we are creating a PyQt window with four buttons for controlling the movement of the Trilobot. We also connect each button to a corresponding method that will send commands to the Trilobot to move or turn.

Step 4: Implementing the Control Logic

Next, you need to implement the control logic for moving the Trilobot. Depending on the hardware and software setup of your Trilobot, you may need to send commands over a wireless connection or via a serial port. Modify the move_forward, move_backward, turn_left, and turn_right methods to send the appropriate commands to the Trilobot.

Step 5: Running the GUI

Finally, you can run the PyQt GUI by creating an instance of the TrilobotControl class and calling the exec_ method of the QApplication class:

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = TrilobotControl()
    window.show()
    sys.exit(app.exec_())

With these steps, you should have a basic PyQt GUI set up to control a Trilobot. You can further enhance the GUI by adding additional features such as sliders for controlling the speed of the Trilobot or input fields for entering custom commands. Have fun exploring the possibilities of controlling a Trilobot with a PyQt GUI!
