Robotic Hand Control by Flex Sensor and Arduino

The present manuscript deals with designing a haptic robotic are, which can be used to pick and place the object. In the paper, a robotic are with four degree of freedom is designed and is able to pick the object with a specific weight and place them in a desire location. Animatronics is the use of mechatronics to create machines which seem animate rather than robotic. Animatronic figures are most often powered by pneumatics (compressed air), and, in special instances, hydraulics (pressurized oil), or by electrical means. The figures are precisely customized with the exact dimensions and proportions of living creatures. Motion actuators are often used to imitate "muscle" movements, such as limbs to create realistic motions. The project idea came to us after watching the movie named "Real Steel". We wanted to make a shadow robot from our curiosity. As the whole body of the robot would have been of much cost, we decided to make a shadow hand instead. Approximating the kinematics of the human hand was our top priority when developing this animatronic hand. Each joint of this hand has a movement range again the same as or very close to that of a human hand, including the thumb and even the flex of the palm for the little finger.
