using new message Age.msg
I need to create a python file that creates a publisher that indicates the age of the robot.
I have created a new message Age.msg:
float32 years
float32 months
float32 days
script:
#! /usr/bin/env python
import rospy
from std_msgs.msg import Float32
print "Age of our robot: "
rospy.init_node("publish_age_node")
pub = rospy.Publisher('/pub_custom_ros_msg', Float32, queue_size=1)
rate=rospy.Rate(5)
age=Float32()
age.years = 5
age.years = 10
age.years = 21
while not rospy.is_shutdown():
pub.publish(age)
rate.sleep()
SOMETHING WRONG HERE
So what is your question?
Looking at your code, this doesn't seem right:
first you make
ageaFloat32, then you try using it like anAge. That won't work.You'll want to
importyour custom message and makeagean instance of that message.I need to make a simple python file that creates a publisher that indicates the age of the robot.
I have created a new message Age.msg:
float32 years float32 months float32 days
By using this Age.msg file I should create the Python file
Thanks!
Ok. Just making sure: have you completed the introductory tutorials about creating your own message and using it with
rospy?Yes, I completed. I also completed publisher and subscriber part
Did that not give you an idea how to import your own message?
Why are you not using the same approach for your
Agemessage?Maybe I am not sure how to do it properly.
Let me try one more time and I come back here later.
Thanks for comments!
I did exactly what was said here, in youtube video: https://www.youtube.com/watch?v=ZPmlF...
But still I am getting --- ImportError: No module named mode_publishers.msg
I just changed node_example to mode_publishers
