Rawbots - Building Balanced Cycle

This video is not quite as clear as my other two in the message I was trying to convey to people but the codes and I apologize for that I'm still trying to wrap my head around how it works myself (I wrote the code but I thought I'd need a negative kd value which just made it issues of not using kd worse).

If you have any questions please leave them in the comments

I made a similar design with two hovers to balance left and right and the motors actually kept it balanced forward and backward.

Problem with that is any collision with the front back will knock it off balance and then part of the hover lift will be lost due to the angle and it thus won't recover.

thanks, I made this same design and ended up with some pretty sick results man! I have 2 questions though. The first one is how did you made it go back and forth? i tried running the motor but that doesn't work. And the second question is how would i make this with hover parts so i can make like a flying hover system where i can ascend and descend on command. Very cool tutorials!

[Joseph Lindsay]

Firstly to make it go back and forth I messed with the balance slightly. So by putting more thrust in one of the jets (and less in the opposite) it will turn and move and stuff.

As for hovers using hovers all you'd need to do (as I did in my bombpod video) was replace the counterbalance with an altitude you can control (instead of the altitude of the other part) and put lift where thrust is. To move thou you'll need a jet or something.

[Joseph Lindsay]

Also if your feeling very adventurous you can try and make it so it balances by counteracting gravity exactly instead of balancing around a set altitude. You can find out the gravity using accelerometers and they are the force required for a part of weight 1 (A 2 CW part if you work in such units).

For the less adventurous just try and get flight working using jets pointed downwards (has more application as you can turn without more pieces)

Is the controller essentially a PID loop?

[janvoslos]

Thanks i messed around a bit with controllers and i got it to work! i have now a hovering vehicle im working on moving it im thinking of jets but by some reason i can't get it balanced...

Well of to work then !

thank you SO MUCH for the tutorial. It`s priceless for a noob such as me :)

Great tutorial, thanks Joseph!
