Mbot1 Self-balancing

#5

Hi @Casnytcha

You should use the Forum’s search bar and enter ‘self balancing’ . You will find quit a lot of information here and I’ve responded to related posts several times - here are a couple of links that you may find of some value:

#6

I wasn’t sure it works like this on mbot1 becose on this topic it was for ultimate bot.

#7

The principles of balancing are the same for whichever bot. However, your original image (where it was impossible to see a Gyro module) shows it using mBot’s own motors which are simple DC motors. I’m fairly sure that PID control is only possible when using Encoder motors.

Inside the red circle you have the gyro module


Here the link with a video (movie) .

So it is perhaps possible only with mbot2 :frowning:

No, I just look on the net to see différences with mbot2. they have encoder motors, but they are on blue color. The one of the mbot1 are yellow like on the movie.

I know now that the black square is the gyro module - BUT its just a black square!

#10

I don’t realy understand your answer…a joke ?

#11

so suspicious…

#12

No, not a joke. The black square was clearly the side of an RJ25 socket - but no hint of what module might have been there.

#13

I’m surprised it works, the board is on backwards.

#14

Dc motors are also placed differently.

#15

The positioning of the motors and the board mounted inside the mBot chassis both make sense (to get the best possible weight distribution over the wheels).

#16

@CommandeR Maybe that’s why, but I do not see how it could distribute weight because the board is on one side.

#17

No - I agree @Rosco but that seems to be the best possible positioning for such a device - see my notes at:

#18

I think it will be better to place the mother board outside the frame, but with little spacers, and the battery inside (like the picture).

#19

I think so, too. Do you have all the components necessary to complete this project?

#20

No, I’m waiting to determinate all accessories I need for the 7 mbots we have in school (differents projects).
Because I would’nt have to order many times for little things.

But, the real question is how to program these one. I try to understand what they use on the example, but I don’t know how to do.

#21

As I said early in my responses to this post: “beware, this sort of programming is VERY complex.”

I think that you are attempting too much here.

#22

Yeah, I cannot do this project even if I need a desperate attempt at a YouTube video. Besides, the module shown in the previous picture is not even in stock anywhere, from what I have looked at.

#23

Yes CommandeR, I’ve seen your previous message. This project is not for tomorrow. I have already code heating in my house with PID, so I think it is a little looks like… (more react/quick)
And my supplier has this module on stock.

I’ve discovered Mbot only one month ago, so I’m a trainee level for now.

#24

Perhaps anyone has the solution here…
Do you know how to translate these block from MblockV3 to MblockV5 ?
Traduction

Only the block “activate the motor M1 with power …”.

Thanks
