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. 


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.

@John Hestness... Using the throttle to control pitch while in the air does nothing!
You have no control once you leave the ground!

@ sqt Ric  john's right you could use it to control pitch in the air.  When riding sport ATV's and dirtbikes riders including myself use the throttle and brake to control pitch while in the air to setup for the landing when jumping.  If you need to bring the nose down hit the brakes.  Gas it to bring the nose up.

Controlling pitch in the air? Wow although the torque would probably do it enough to let you adjust things a bit. Just don't blow the engine in mid air.

@ T.D.  It's a sport quad.  There is a method to madness It won't blow.  I take really great care of my 4wheeler.  I've been trail riding sense I was about 5.  My friends and I R True Full Trottle Junky's  :)

Yeah but a computer w/o tach readings might do it.

My 4wheeler has a rev limiter,  and it does get used.  LOL

I know there are many mechanical engineers and even aerospace guys in this community site who can correct me if I'm wrong, but the torque from a bike engine doesn't act in a plane that would affect the lifting of the "nose" once both wheels have left the ground.

Additionally any effect the tire tread would have in the air must be negligible!

I haven't ridden MX since my 250cc in the '70s, but I do remember having to setup for a jump at the last split second at the end the ramp... I never considered it possible once the tires left the ground(?)

Using the brakes in the air?.... sounds like something Wiley E. Coyote would do on The Roadrunner show.

I have some friends that restore those bikes and turn them in to flat trackers.  Sqt Ric it's true though.  U should get out and do a little riding.     Since the 70's?  LOL

@Sgt Ric: I think it has to do with the rotational energy stored in the tires. I don't think the air has anything to do with it. But if the tires are spinning and the brakes are hit wouldn't it put some torque on the vehicle pushing the nose down a bit? The set up is still necessary since these adjustments are just that.
