Simply download it and upload on the Husarion Cloud web IDE. To connect your CORE2 to the Cloud follow this tutorial on Husarion webpage.

Then install hVideo app available here on Play Store. Pair your phone's camera with the Cloud by simply scanning QR code.

Attach phone to the robot, turn it on and click on it in the Cloud. You will see web user interface.

On the left you can see a joystick, to easily control your robot via web browser in any phone. Or you can simply steer it using arrow keys on the keyboard. Next to it there is a gear shift to control robot's speed.

Hope you will enjoy.
