Rospy has no attribute ServiceProxy
I have been trying to create a script that will delete and spawn objects in gazebo. When I try to run rospy.ServiceProxy, it keeps telling me that module rospy has no attribute 'ServiceProxy' although I have seen in various tutorials online that it does. This is my entire script:
import rospy, tf
from gazebo_msgs.srv import DeleteModel, SpawnModel
from geometry_msgs.msg import *
if __name__ == '__main__':
print("Waiting for gazebo services...")
rospy.init_node("spawn_products_in_bins")
rospy.wait_for_service("gazebo/delete_model")
rospy.wait_for_service("gazebo/spawn_sdf_model")
print("Got it.")
delete_model = rospy.ServicePoxy("gazebo/delete_model", DeleteModel)
spawn_model = rospy.ServiceProxy("gazebo/spawn_sdf_model", SpawnModel)
with open("$GAZEBO_MODEL_PATH/crocodile_buoy/model.sdf", "r") as f:
product_xml = f.read()
orient = Quaternion(tf.transformations.quaternion_from_euler(0,0,0))
for num in xrange(0,12):
item_name = "croc_{0}".format(num)
print("Deleting model:%s", item_name)
delete_model(item_name)
for num in xrange(0,12):
bin_y = 2.8 * (num / 6) - 1.4
bin_x = 0.5 * (num % 6) - 1.5
item_name = "croc_{0}".format(num)
print("Spawning model:%s", item_name)
item_pose = Pose(Point(x=bin_x, y=bin_y, z=2), orient)
spawn_model(item_name, product_xml, "", item_pose, "world")`
The output I get is:
Waiting for gazebo services...
Got it.
Traceback (most recent call last):
File "/home/jehan/PycharmProjects/spawner/main.py", line 11, in <module>
delete_model = rospy.ServicePoxy("gazebo/delete_model", DeleteModel)
AttributeError: module 'rospy' has no attribute 'ServicePoxy'
Any help would be greatly appreciated as I am relatively new to ROS and gazebo! I am using ROS noetic on Ubuntu 20.04.
Hi @jdastoor3 this is a syntax error. It should be
ServiceProxy
vsServicePoxy
