Rif.: NXT Legway problem

[GabrieleC]

Hi Guys, sorry for my English but i hope someone answer me.

I have need your hel, i do not i think by to find forum most suitable for get answers.

I have i built a Legway, with an accelerometer sensor with their respective axes XYZ the robot manages the axles but not it remains  in the balance.

I found two programs including one i modified by putting only engines,but it doesn't work as it should.

I attach image legway and program.

I wait answers, if you need more infor are here! 🙂

Ciao Gabriele,

il programma che hai sviluppato rileva i valori dell'accelerazione sui 3 assi, li visualizza a video e, con un coefficiente moltiplicativo di 10 li mette in ingresso alla potenza dei motori.

Ce'è un errore di fondo in tutto questo: il valore che viene restuito dagli accelerometri è in m/s^2 mentre il valore di potenza in ingresso al blocco "motor on" è adimensionale e variabile tra -100 e 100. 

Moltiplicando il valore dell'accelerazione x10 ad ogni ciclo, fai saturare il valore della potenza rendendo il Robot instabile.

Non mi è chiaro cosa vuoi fare di preciso... quindi per ora ti consiglio di guardare meglio gli esempi e l'help delle funzioni.

English:

Hello Gabriel,
the program you have developed detects 3-axis acceleration values, displays them on the screen and, with a multiplier of 10 puts them at the entrance to the engine power.
There is a basic error in this code: the value that is returned by the accelerometers is in m / s ^ 2 while the value of input power in "motor on" function is dimensionless and varies between -100 and 100.
Multiplying the value of the acceleration at each cycle x10, saturates the power value by making the robot unstable.

I am not clear what exactly you want to do ... so for now I suggest you get a better look at the examples and help functions.

Bye

Hi, Thanks for answer.

My main problem is only the stability the robot, because detects the tilt of the axis but does not stay straight.

I have another program found on the web and modified by me, even if I put some random value for test it in real time on my robot using only the x-axis. This can be useful by changing some parameter?
