An international team of scientists is working to connect human thought patterns to robotic actions. Controlled humanoids present a new world of mobility for some and a disaster clean-up tool for others. (May 30)
Mind control is real.
Electroencephalography (EEG) measures bioelectrical activity in the brain - specifically bio-electrical signals generated by the cerebral cortex nerve cells.
By putting the EEG electrodes onto your forehead, you can send signals including those interfering ones in the surrounding environment to the sensor. A common-mode rejection algorithm is used to filter the interfering noise so as to detect the EEG signals. The signals are then transferred to the controller to make the robot move forward and backward, and make turns accordingly.
A model helicopter can now be steered through an obstacle course by thought alone. The aircraft's pilot operates it remotely using a cap of electrodes to detect brainwaves that are translated into commands.

Researchers developed a brain–computer interface (BCI), with implanted microelectrode arrays located in the supramarginal gyrus (SMG) and primary somatosensory cortex (S1), that can help decode internal speech.
