User Manual

To program robotics applications, VisualCircuit tool requires the following dependencies. You can skip this step if you are not interested in programming robotics applications.

Installation over Ubuntu 20.04 LTS:

  • ROS Noetic: Desktop-Full Install recommended, includes Gazebo. Link.
  • Gazebo 11

Full ROS package:

 sudo apt install ros-noetic-desktop-full

Current Dependencies

Python 3.8 and above, pip3, Tkinter and OpenCV:

(Ubuntu 20.04 comes with Python 3.8.2)

sudo apt-get install        \
python3-tk python3-opencv   \
POSIX_IPC and XClip:
sudo pip3 install posix_ipc
sudo apt-get install xclip
NodeJS (14.4.0) and npm (6.14.5):
sudo apt-get install curl                                       
curl -sL | sudo -E bash -
sudo apt-get install -y nodejs
node --version
npm --version


Download Direct .zip Package:

You can download the .zip package from here

Alternative Method:

Clone and install IceStudio from icestudio repository:

git clone

Check if installation is successful. If it is successful, the application will succesfully start.

cd icestudio
npm install
npm start

Clone VisualCircuit Repository:

git clone

Go to the downloaded VisualCircuit repository and copy app folder and package.json file. Navigate to the icestudio directory and paste the files in that directory. Merge all the files that are conflicting.

Once the merge operation is done, rename icestudio directory to anything you want. I will rename it to ‘visualcircuit’.

Running the Tool:

Run VisualCircuit:

cd visualcircuit
npm start

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.
