Collaborative robots have been increasingly used in industries. This master thesis proposes a new mode of interaction to perform an industrial assembly task that employs an LCD, a Leap Motion controller and a camera as hardware and lets them interact with a Niryo One robot over ROS. The robot is an educational one, 3D printed with 6 degrees of freedom. The camera is a webcam, placed above the robot, focusing the workspace and displaying images on the screen. A new touch emulation system was proposed using the display and the Leap Motion controller. It consists of an initial calibration step which creates a virtual representation of the screen.
