RC car automatically balancing and driving on two wheels #3 - body added

nice

[Andu1999]

this is a piece of crap omg u r driving on 2 wheels good 4 u

[fireraisr]

awesome project. I just started with the butterfly and so far really like it. Those that are saying it's crap don't know what it takes to program something like this. Well done.

[dammachines]

Sweet!! Just finished reading your paper where you documented your roll angle and roll angular rate gains. So did you basically use a PD type control to establish equilibrium? If not, would you be willing to share some of the details?

[enfilade999]

Yeah I used PD control and fed the roll angle and angular rate back and actuated the steering to reach the equilibrium angle. One of the most important things was using the control output filter, which is discussed in the paper.

i'm sure its not "crap" why not use accelerometers instead of that goofy stick/pot.? neat project though

[enfilade999]

I started off using an accelerometer but I ended up having a lot of problems with noise and also with signal discretization due to my cheap microcontroller. So in order to finish up in time, unfortunately I had to use the goofy stick/pot setup.

[enfilade999]

I don't think discretization is the word I was looking for but I can't think of the right word.

Yeah this is a Bunch of crap

[enfilade999]

Why is it a bunch of crap? The arm on the side is connected to a sensor and moves freely. It doesn't support the car. The car's steering is controlled by a microcontroller and responds to the car's motion to balance it.

you had a f**king thing holding it up

[enfilade999]

nope, see previous comment

[kooryfery]

what the fuck was that little stick on the side

[enfilade999]

Its a free moving arm connected to a potentiometer. It doesn't hold it up.
