A robotic arm capable of being controlled by a hand gesture is disclosed. A movement of the robotic arm can be controlled by using a gyro sensor, a flexible sensor, and the like. Wireless communication can be performed between a main body of the robotic arm and a controller using Bluetooth. Accordingly, the present invention can provide a new interface that does not require a long term of skill course when controlling a complicated device or robot.;COPYRIGHT KIPO 2016
