Abstract:Different from the traditional mode of operation of the manipulator, a somatosensory manipulator is prooposed and designed. The gesture sensing manipulator had 5 degrees of freedom (5DoF) altogether, wtih the joint work of the upper and lower machine model adopted. Data read and internal operations were resonsible by using C# to compile the computer, and coordinate somatosensory information obtained by Leap Motion sensor was transformed into joint steering gear rotation angle actually needed, and through the Bluetooth 40 module real time transmitted to the lower computer. The lower computer was used of Arduino nano microcontroller unit (MCU), responsible for receiving data and control steering angle value, through the pulse width modulation (PWM) signal transmitting to the simulation of steering gear, to achieve the desired operation. Human arm and finger movements to imitate and small parts handling can be realized in a quite far distance.
