A new wave of mind control will be upon us soon, this time for the end user!
We have seen the WiiMote bring greater levels of human input to gaming in a huge scale (over 29.62 million Wii units sold at the time of writing). The Wii also brought down the cost of this technology so more people could buy it. The Nintendo DS (NDS) and Apple iPhone brought touchscreens to the mainstream.
So why not take game control to the next level? Emotiv is doing just that, mind control for PC games. I first saw this new interface device back in early 2008 thinking it would be amazing if brought in the real world. My idea was to interface this with a Windows program for remote controlling a NXT robot. If a success, interfacing it with a humanoid robot.
In the last week I have been playing with the SDK to great success! The “EmoKey” program can link different thoughts, emotions, or facial motion to input key commands to your Windows PC which I can then use to control a robot. Sadly the Emotiv EPOC costs $299 (USD), a bit much for what I’d be doing… I did not even know *if* this would work for physical objects (what I am trying to do) up until a few days ago! I was watching a recording of the Discovery’s new show “Prototype This!” where the team built cars that would shut off if the builder gets angry (which also triggered for excitement). There was a beautiful test where they bent a spoon by “pushing” with their mind at the spoon, sending input to the computer, then sending an articular a message to pull on the spoon (seen below).
You can see the full episode on the Discovery website until January 15, 2009.

Public release is set for Christmas 2008!
Will this make PC gaming cooler? Will mind control be successful? Will Nintendo fight back? Where will this next gen technology be going next?
I have wanted a good place to save and share robot related files. We have YouTube for videos, which works very well. But the file sharing has not come as far yet. This is understandable, though, as more people will watch videos then download files, and they need to make money also.
Listed below are the best file sharing sites yet:
MediaFire – Tons of ads, hard to find the little “download” button once on the page. You can add a description and title for your file. Files will stay online forever.
SkyDrive – Personally, I like the folder layout of SkyDrive, although you can not yet drag files from one folder to another – you must re-upload the files. The files do not have a page for them where you can add a description or title. Online time for files is unlimited.
I feel that we will soon see good file sharing sites like YouTube.
If you know of any good file sharing sites, please let us all know by posting a comment!
Jon Hylands sent me a link today for anti-static bags with the note:
“The anti-static bags are great – Digikey sells them in 100-packs for $6.18 [CAD].”
BryanB’s line-following robot “Arty” got better times with each loop at Fall Chibotica 2007.
Although a small factor, the warmth the tires got from running may have caused them to get more traction. The added traction would have then caused the robot’s tires to slip less, and the robot would go faster.
History repeating itself?
I took this video at iHobby 2007 (October 21 2007):
On YouTube there is a video from CIRC 2007:
You will see that Rob’s Lego Mindstorms RCX robot “Not Just Brute Force” (in the middle of the older video), gets beat-up in the same way; both times his robot tips back, and both times it was with a fast robot.
While Not Just Brute Force did not win at iHobby 2007, there is much to be learned from his design!
I went to iHobby Expo last Sunday, October 21, 2007, and met, and made friends!
When I arrived at iHobby Expo at about 9:00 A.M. CST, I went straight back to the pits to make sure my robot worked. About 30 minutes later Mike (also known as “Gort”) showed up with his robot Boomer (see below)!
After my Lego Sumo robot, “Mean Puppy”, was ready I headed over to the Chibots booth and found Steve Hassenplug from Team Hassenplug, Royce Pipkins leader of Chibots (thanks Royce for the great time)!
By the end of the day I had many more friends that I’m sure I’ll be talking to again! Two are Bryan Bonahoom, and Rick Brooks (creator of “ExSpurt”, to only name one robot).
