In our work, the main aim of a making human hand tracking system is to create interaction between human hand and Robotic Module. Human-machine interaction gives the relation between human and computer. The Robotic system is to be controlled using Leap motion controller in X, Y and Z direction. The Leap Motion Sensor is a small device able to sense human hands above it and try to keep track of them. Hence, when controlling the robot, the user can use touch-free control experience. A mobile robot can be controlled by translating the multi-finger gestures into commands via leap motion controller. In this work the hand gestures are observed and transferred to the computer. Then by translating the input leap motion signals into commands we can control the robot. The main technology behind leap is normal user interface, gesture recognition and motion control. However, we cannot achieve the capability of a human hand completely, this system can be used in all the areas where robotic hands are manually controlled and reduces much of effort and being used while handling with traditional controllers.
