You can download the VisualCircuit-2.1-linux64.AppImage package from here

Running the Tool:

Run VisualCircuit:

if you downloaded .AppImage file sucessfully then downlad and run file from

to install the dependencies.

Next go to folder containing the ApppImage and in terminal run


Well Done! you have Successfully Installed the VisualCircuit


Now it’s time to play with it.

Build first application:

We are now going to create our first running robotics application using Visual Circuit.

First of all, on the top right corner you will find some options like Basic, Block, and etc.


Click on the Blocks and following menu will be poped up.


Expand the openCV.


Select the camera and place it.


Again go to openCV. This time select the screen and place it.


Now connect the camera to screen. click and hold on the out going edge of camera and join it to the in comming edge of screen. alt_text

Your application has been setted up. It’s time to execute your first application.

To do so, first saved your application by pressing ctrl+s. It will ask you to name your application.


After doing that click on the files from the top left corner and following menu will be poped up.


Go to build and press Python-ROS-Neotic alt_text

Here you go your application is setted up. Congratulations buddy.
