In the following code rospy.loginfo is used instead of print()
#! /usr/bin/env python import rospy from std_srvs.srv import Empty, EmptyResponse # you import the service message python classes generated from Empty.srv. from geometry_msgs.msg import Twist def my_callback(request): rospy.loginfo("The Service move_bb8_in_circle has been called") move_circle.linear.x = 0.2 move_circle.angular.z = 0.2 my_pub.publish(move_circle) rospy.loginfo("Finished service move_bb8_in_circle") return EmptyResponse() # the service Response class, in this case EmptyResponse rospy.init_node('service_move_bb8_in_circle_server') my_service = rospy.Service('/move_bb8_in_circle', Empty , my_callback) # create the Service called move_bb8_in_circle with the defined callback my_pub = rospy.Publisher('/cmd_vel', Twist, queue_size=1) move_circle = Twist() rospy.loginfo("Service /move_bb8_in_circle Ready") rospy.spin() # mantain the service open.
I tried looking up in google to understand difference between print() and rospy.loginfo, but I couldn’t get it.
Would you please tell me:
- What’s the difference between rospy.loginfo and print() ?
- Why are we using rospy.loginfo here, in the code above?
