Step 17: Inspired by Sci-Fi Movies: Brainwaves, Measuring, Story of My Project...

Yes it is true... I was inspired by the Star Wars Saga and I was amazed by the Force. I always wanted to make something that can help me to get closer to this feeling and then I made a research in neuroscience. Last year I won a national competition with my brainwave based project and this year I made this virtual reality robot so actually this is the further development of my original project. In the world of Star Wars the Jedi knights were able to move objects with their thoughts and with the help of today's technology I was able to create a gadget that approaches the Force users' experience.

Don't worry, we can't steal your thoughts... There are millions of neurons communicating in your brain right now with electrical impulses. This can be measured by the device that I have shown you. To control this little robot we are using Alpha and Beta waves. Read more below. Brainwaves are detected using sensors placed on the scalp. They are divided into bandwidths to describe their functions (below), but are best thought of as a continuous spectrum of consciousness; from slow, loud and functional - to fast, subtle, and complex.

How to control the robot?

It is pretty easy... Try to focus on your right hand to move right, try to think on floating your left hand to move left and blink to move forward then blink to stop. The ultrasonic sensor helps you if there is any problem.

Delta brainwaves are slow, loud brainwaves (low frequency and deeply penetrating, like a drum beat). They are generated in deepest meditation and dreamless sleep. Delta waves suspend external awareness and are the source of empathy. Healing and regeneration are stimulated in this state, and that is why deep restorative sleep is so essential to the healing process.


Theta brainwaves occur most often in sleep but are also dominant in deep meditation. It acts as our gateway to learning and memory. In theta, our senses are withdrawn from the external world and focused on signals originating from within. It is that twilight state which we normally only experience fleetingly as we wake or drift off to sleep. In theta we are in a dream; vivid imagery, intuition and information beyond our normal conscious awareness. It’s where we hold our ‘stuff’, our fears, troubled history, and nightmares.


Alpha brainwaves are dominant during quietly flowing thoughts, and in some meditative states. Alpha is ‘the power of now’, being here, in the present. Alpha is the resting state for the brain. Alpha waves aid overall mental coordination, calmness, alertness, mind/body integration and learning.


Beta brainwaves dominate our normal waking state of consciousness when attention is directed towards cognitive tasks and the outside world. Beta is a ‘fast’ activity, present when we are alert, attentive, engaged in problem solving, judgment, decision making, and engaged in focused mental activity. Beta brainwaves are further divided into three bands; Lo-Beta (Beta1, 12-15Hz) can be thought of as a 'fast idle, or musing. Beta (Beta2, 15-22Hz) is high engagement or actively figuring something out. Hi-Beta (Beta3, 22-38Hz) is highly complex thought, integrating new experiences, high anxiety, or excitement. Continual high frequency processing is not a very efficient way to run the brain, as it takes a tremendous amount of energy.


Gamma brainwaves are the fastest of brain waves (high frequency, like a flute), and relate to simultaneous processing of information from different brain areas. It passes information rapidly, and as the most subtle of the brainwave frequencies, the mind has to be quiet to access it. Gamma was dismissed as 'spare brain noise' until researchers discovered it was highly active when in states of universal love, altruism, and the ‘higher virtues’. Gamma is also above the frequency of neuronal firing, so how it is generated remains a mystery. It is speculated that Gamma rhythms modulate perception and consciousness, and that a greater presence of Gamma relates to expanded consciousness and spiritual emergence.

<p>can i transmit Webcam data over HC 12 ?</p>
I have a problem with this code. The controls work, but after a while the motors keep running without giving a command (they keep running even with the transmitter off) It seems the arduino uno gets stuck in a case. I added three 100nF caps to each motor - without success. Has anyone else experienced this problem?
<p>Great idea. I got excited to use the FPV Wifi camera you link to for another project so went and got a couple off Ebay. Unfortunately what you link to is not a Wifi camera. May have been at one time and is 'advertised' and described by the 'store' as Wifi but they obviously either don't know or don't care what they are selling. Caveat Emptor to anyone else thinking of this.</p>
<p>Yea, I also got that camera and it does not seem to have any wifi. I also can not figure out what the wires are. When I open it up to look the yellow is marked ad positive and red as negative. Nothing is happening when I connect red to 3.3 V and black to ground so I am not sure it is working at all anyway.</p>
<p>I did get that far. You figured out the same polarity I got. If you have the SD card installed and then connect the black wire to the 3.3V it will start recording video for as long as its connected to the 3.3V. If you 'pulse' it by momentarily touching black to 3.3V, it'll take a screen shot and store it as a jpg in a separate folder on the SD card. It also has and records audio with the video. </p>
<p>Dualism is a lie.</p>
Hi I'm having trouble buildibg it. The uno-board (receiver) seems to receive signals from the transmitter (blinking while turning the joystick) but the motors dont run. Is it posdible that this joystick is not compatible?
Plz need help <br>
<p>Hello, yes I am here.</p>
For how many distance the camera work? It is work on wifi? <br>
For how much the camera work? And it work on wifi? I need same wifi source to connect it to my phone?
Can i do it without programing skills? I can just copy the code and past in the prog.app?
Yes you can ☺
Hello i need your help with sonething please can i you with email or any app like facebook ,....? This is my email Roudyhazzouri2001@gmail.com
Thx :)
<p>Hi, AMAZING PROJECT, really loved it, want to try out something similar on my quadruped project,</p><p><a href="https://www.instructables.com/id/QUATTRO-the-Arduino-Quadruped-Robot/">https://www.instructables.com/id/QUATTRO-the-Arduin...</a></p><p>but i have used up all my pins for the servos, any suggestions?</p><p>thnx in advance</p>
Bonjour, <br>Bravo pour votre projet. Une question : comment avez vous branch&eacute; la cam ?<br>D'avance merci
<p>hey, thanks for all the links and step by step instructions. my parts are all ordered and are begining to come in the mail. I got the double gear box first..what ratio did you build the double gear boxes? they can be built in 4 configurations...12.7/1 or 38.2/1 or 114.7/1 or 344.2/1. I am happy to play around to see what works, but what did you use??</p>
<p>I found this just now and thought it might help.</p><p>https://www.pololu.com/product/114/specs</p><p>If you look in the different tabs (specs, faqs) there is enough info to know what rpm each ratio will get.</p>
<p>Same here. My gearbox arrived today and I was wondering the same thing. The ratio used in the video looks good to me, so I was wondering which you used.</p>
<p>wow nice</p>
<p>amazing! voted all 3!</p>
good work
<p>very nice!!!!</p>
<p>Magnifique! Excellent Build!</p>
<p>wow. This is very good. </p>
<p>a tank controlled with brain??cant imagine what a full size will look like lol!</p>
<p>Du bist mir wirklich am besten, ich bin sehr stolz auf Dich! Viel Spa&szlig;, Erfolg und Ausdauer! Ich bin immer bei Dir Schatz! :)</p>
<p>Dankesch&ouml;n Kicsipuca! :) </p>
This is the coolest thing I've seen ever
<p>Thank you very much! You can give me a kindly Vote. ;) </p>
<p>would you be willing to sell this to me on ebay?</p>
<p>Sorry :) I can't...</p>
<p>verry nice</p>
Oh this is a verry nice project.I vote for you:))
