I hacked a toy robot to control it with my brain:

• If I concentrate the robot goes forward.
• If I meditate, the robot turns left.

Here's a little video :-)

The EEG headset I am using to analyze my brainwaves is the Neurosky Mindwave Mobile.

The remote of the toy robot is hacked and connected to an Arduino microcontroller.

To control the robot I used these 2 simple principles:

• Meditation produces alpha waves (frequency range: 7.5-12.5 Hz)
• Attention produces beta waves (frequency range: 12.5-30 Hz)

So by isolating these 2 frequencies in my brainwaves, I can trigger the right signals to control the robot.

Here is the chain of events:

• The EEG headset records my brainwaves.
• The brainwaves are analyzed on my computer to isolate the right frequencies.
• The computer is connected to an Arduino microcontroller. The Arduino gets a specific input for each frequency detected.
• The Arduino is connected to the robot remote (hacked)
