This paper proposes a novel method of development of low cost robotic prosthetic arm with five fingers and rotating wrist using a 3Dprinting technology. Amputation generally refers to removal of parts of limb due to trauma or surgery. Most of the EEG and EMG prosthetic hands have several shortcomings such as low intensity, high price, et al. This has blocked the amputee people from practical realization. To overcome these problems, we are using leap motion sensors which can replicate the function of original hand. Servo motors are used to achieve flexibility of up to 90 degrees and an Arduino is also used to program the device. Finger motions are controlled by servomotors which work as actuators while the rotation of each servomotor was controlled using microcontroller. This device can help a partially amputee person to lead a normal life in society and gain his self-esteem.
