I want to control 10 Dynamixel motors using ROS PYTHON, I am succeeded to control 6 motors at a time. But while not all 10. What should i do to move them using my slider control program, As i started my executing my code ALL MOTORS ARE MOVING IN RANDOM DIRECTION

HERE IS MY CODE

#!/usr/bin/env python
import sys
import time
import rospy
from std_msgs.msg import Float64
from Tkinter import *

rospy.init_node('adi', anonymous=True)
pub1 = rospy.Publisher('/joint1/command', Float64, queue_size=10)
.
.
.
pub10 = rospy.Publisher('/joint10/command', Float64, queue_size=10)

def a():
    pub1.publish(3)   # It sets the motor to center position
.
.
.
.
    pub10.publish(3)
    print  w1.get(), w2.get() , w3.get(), w4.get() , w5.get() , w6.get() , w7.get() , w8.get() , w9.get() , w10.get() 
    pub1.publish(w1.get()*0.01)
    .
.
.
.
         pub10.publish(w10.get()*0.01)


master = Tk()
master.title("ADI")
w1 = Scale(master, from_=-360, to=360, orient=HORIZONTAL,length=300)
w1.pack()
.
.
.
w10 = Scale(master, from_=-360, to=360, orient=HORIZONTAL,length=300)
w10.pack()
Button(master, text='Move', command=a).pack()
a()
master.mainloop()

I used 2 different files a1.py & a2.py to write 2 different functions of five arguments (for each motor) in each py

Thanks for your reply, But it is not related to the Voltage drop. I didn't find any voltage drop in it & i am using

While i am launching roslaunch my_dynamixel_tutorial controller_manager.launch i am getting this error. It works fine till yesterday & i controlled dynamixel motors with my algorithm. But all of sudden it appears today after i run catkin_make

Thanks for all, for your valuable suggestions & support.

i am working with ros & dynamixel motors for past 10 months. few days back i observed dynamixel_sdk & dynamixel_workbench packages & i installed it to see what extra features in it. As a process of installing, i cloned some files form git hub, in that files some consists of same package. while i am running my code it is calling that file instead of the original file. After a long detailed observation i found this.

I resolved my issue now.

Once again thanks for all.

Thanks for all, for your valuable suggestions & support. i am working with ros & dynamixel motors for past 10 m

@gvdhoorn i found my error & i updated the same in question with how i resolved the error

i did that but there is no change in that error
