A system and method for controlling a remote control assembly with precision using signals detected by low-cost brainwave sensors. A brainwave detection unit senses brainwaves and produces corresponding data signals. The brainwave detection unit is capable of detecting the intensity of alpha waves and beta waves without complex waveform analysis. A control unit receives the data signals from the sensors of the brainwave detection unit. The control unit contains circuitry that sets a range for the brainwaves. The range is divided into multiple levels. The control unit produces different control signals as the data signals rise and fall between the levels of the range. A remote controlled assembly is provided that operates in response to the different control signals.
