Riding wheelies with my Arduino Wheelie controller!

 

This video show that the controller working for the first time.    !!!!!Awesome!!!!!!

I could barely keep a wheelie up and going before I started using my controller.

 

 

 

 

Tuning the code a little more before the ride.                      >>>>>>>>>>>>>>>>>>>>>>>>

 

  

 

 

 

 

Ever since I was a kid I wanted to ride wheelies.  So I built a Arduino Wheelie Controller and started enjoying longer, safer wheelie'ing.  I use an Arduino Duemilanove ATMEGA 328 to control a LARGE  digital servo powered with a homemade servo power curcuit, coupled to a hydraulic hand brake.  The handbrake is connected to a steel braded brake line that runs down and connects in place of the rear hydraulic brake reservoir.  The controller uses a triple axis accelerometer and a single axis gyro to calculate when and how much brake to apply.  This controller can be used on 4wheelers and motorcycle with rear disc brakes. 

Controller

1.)Arduino Duellinove

2.) Triple axis accel & single axis gyro  "Black Box"

3.) Power supply for LARGE servo

4.) LARGE DIGITAL High speed & Torque servo w/ metal gears

 

 

 

 

 

 

 

 

  I connected my servo to a handbrake like this one and mounted it under the rear fender. >>>>>>>

 

 

I used this adapter to connect my handbrake to the rear brake master cyclinder.

Hey Russell, nice hack! A buddy in the area has a hopped-up Jeep that pulls wheelies. I should turn him onto your method to keep that beast under control!  :) Another thing that comes to mind is the Centaur by Segway- a 4 wheeled off-road wheelie-riding gadget that never went to production.

Good work. Enjoy and be safe.

I checked. It's not April 1st.

@ OLE It's no joke it really works. :) 

@ john is it a rock crawler type jeep?  yes it will help to keep the front tires down when climbing.  Whats funny is the code for this project is very simple. Although I have lost it due to a computer crash.   Now I know it my head becuase it took about 3 months to get it figured out.

original one !

what the controller is actually doing it to limit the throttle at the points it gets to 45 degrees angle ?

so your gas now is some kind of pot ? :)

No It only uses the 3 axis accel and single gryo.   The picture of it hanging in the tree is how i configured it.  I did not have it configured this high in the video.  pic taken afterwards.  Controller only controls the rear break.  It is intended to help u learn how to ride a wheelie but not to be used as a fail safe.  It wont ride the wheelie or work the throttle but it will tap the brake to from looping out.  flipping backwards.  I can adjust it any way I like but must be careful.  I can trottle over it, as it can snap the front end down sending me over the handle bars.  It takes effort and lots of time but it works.  SAFEFY FIRST

Thats pretty smart to not let your stuff control the gas since there could be bugs. Thats so simple and elegant I love it. Maybe start selling the units as safety systems. More testing will be needed but something to keep 4 wheelers from going over might be a selling point for parents. Although it will also limit the grade of a hill you can climb.

Nice Job!   I understand what you said about using it as a training aid, but I was wondering if you have tried controlling the throttle instead of the brake?   Another idea (not saying its a good idea) would be to control the vehicle pitch with the throttle while in the air during a jump.

 

Do you need a 3 axis accel or is that just what was there?

Comment by Russell B. Sutton on April 30, 2011 at 11:24am

No way would I try controlling the throttle on this quad way to dangerous.  U need a 3 axis accel.  

You could use a dual axis accel but I don't recommend it.  I used 2 axis to determine pitch of the quad.   I use the 3rd axis to tell my program that the quad or motorcycle is standing up and is not fallen over.  When i was testing it on the bench i knocked over my test stand and the brake servo went crazy.  This answered the question of what would ha[[en if you fell over on a motorcycle.

Great idea!
I ride street bikes, and have been dreaming of an automatic "wheelie" button forever.
That obviously would have required control of the gas as well as the brake, and while it shouldn't be hard to do on modern "ride-by-wire" bikes, I still think it's a little too dangerous to try.

Your project is nothing less than awesome. Keep it up!

I got the Idea stunting streetbikes & 50's at our local parking lot.  An auto wheelie button is a death wish but would be cool. :)  I only spent maybe $500 to build it.  It took about 6 months of testing on the bench before I put it on my 4wheeler.  I used the 4wheeler because it was safer to use and work with.  Plus it has lots of room to mount the extra brake handle and servo.
