hola estoy asiendo un proyecto de un brazo robótico y estoy utilizando arduino y si funciona bien la interfaz entre arduino y labview pero el problema es que los servo motores no hacen lo que deberían porque no se ubican en el ángulo correcto de echo todo el tiempo se mueve el eje y no se queda quieto en un ángulo. ya utilice el ejemplo que viene en labview e hice mi propia VI de control de servos y ya cambie los tiempos de l case estructure de las VI de init de arduino 1000 a 2000 y varios valores mas para ver que tarde menos pero siguen los servos sin quedarse estables.

hi,
try to post your question in english.
this probably helps to get answers..

English translation:
hello,
I'm have a robotic arm project using Arduino with a successful interface between arduino and labview. The problem is that the servo motors do what they should because they are located at the correct angle, but the shaft moves the all the time and will not sit still at an angle. I use the example that comes in labview and made my own servos and control. I changed the case structure for the arduino init VI from 1000 to 2000 and several more values to see that take less but the servos remain unstable.

Are you using a feedback loop with tolerance so that the shaft motor does not get an adjustment signal?
How do you determine that the shaft is at the correct angle? Does that sensor have a noisy signal? Noise could cause unwanted movement / adjustments with the shaft.

If the servo is unstable is sure you're working with analog servo, if you want to get presicion you should use digital servomotors, such Dynamixel - Best DC Servo

i have trouble running the servo example for interfacing with arduino.
VISA is facing some problem. i am not able to find out what, can you help me.
