roslaunch yumipy yumi_arms.launch issue
Closed this issue · 5 comments
Hello,
I have been having an issue connecting to the YuMi robot with the YuMipy package. The package appears to be have been installed correctly with autolab in a ROS Jade catkin workspace and the server nodes are running on the flexpendant. However when the PC is connected to the service port of the robot via Ethernet cable and the command roslaunch yumipy yumi_arms.launch is executed from within the catkin workspace, the following response and error messages occur:
... logging to /home/ezzdtb/.ros/log/9c1eacd6-7379-11e7-a61e-54ee7501cfc6/roslaunch-LEZN04907-3300.log

Is there any solution you can recommend to resolve this error?
Kind Regards

Apologies for the late reply.
Looks like either yumi_arm or the service definition is failing to import. Could you try just opening a python console and running
from yumipy.yumi_arm import *
from yumipy.srv import *
One of these two should fail, and that stack trace should give a better idea of what's happening.
Hi,
I created a test ROS package with a python script containing the commands in and ran one at a time whilst commenting the other out. I tried this on the PC I was using and did not have the robot connected, these are the error messages that I got by running each command:
for from yumipy.yumi_arm import *
error is:

It seems that with either of the commands that a module named IPython is missing.
Yeah looks like you need to install iPython.
Just pip install iPython and that error should go away.
Hello,
I need to use it in Window10, what can I do for it?
I have the same problem and I don't know what to do.
I installed iPython but without success do you have a proposal?
