The objective of this research was to design and construction of the system for control robot arm using LEAP Motion Controller. This research has adapted the principle of LEAP Motion Controller and servo motor control. The designed and constructed the project was composed of 3 main parts: 1) detector part, 2) signal control and processing part using microcontroller ATMEL 328 on board (Arduino UNO R3) and 3) display part consists of a robotic arm with a handle two inches. The results of functional testing shown that the system can handle and control the movement of the robot arm to the objectives of the project.
