Baxter_Gazebo: can't get current joint states #122

pipothy · 2018-04-17T14:40:28Z

Hi,

I have an issue with running any of the code to move the robot. I get the below error when I run the joint position waypoints example:

$ rosrun baxter_examples joint_position_waypoints.py -l right Initializing node... Traceback (most recent call last): File "/home/pipothy/ros_ws/src/baxter_examples/scripts/joint_position_waypoints.py", line 191, in
main() File "/home/pipothy/ros_ws/src/baxter_examples/scripts/joint_position_waypoints.py", line 181, in main
waypoints = Waypoints(args.limb, args.speed, args.accuracy) File "/home/pipothy/ros_ws/src/baxter_examples/scripts/joint_position_waypoints.py", line 45, in init
self._limb = baxter_interface.Limb(self._arm) File "/home/pipothy/ros_ws/src/baxter_interface/src/baxter_interface/limb.py", line 121, in init
timeout_msg=err_msg) File "/home/pipothy/ros_ws/src/baxter_interface/src/baxter_dataflow/wait_for.py", line 55, in wait_for
raise OSError(errno.ETIMEDOUT, timeout_msg) OSError: [Errno 110] Right limb init failed to get current joint_states from robot/joint_states

EDIT: When I echo the joint_states topic, I can see data on it so the topic isn't empty.

I already had ROS installed, but other than that, I followed the installation instructions at the link below line by line. I used the commands for kinetic and stopped after launching the baxter world: http://sdk.rethinkrobotics.com/wiki/Simulator_Installation
I then enabled the robot and ran the command to start the example: http://sdk.rethinkrobotics.com/wiki/Joint_Position_Waypoints_Example
This produced the above error.

Am I being silly and have forgot to do something, or is this a genuine error? Apologies if it is me being silly, I can't seem to find anything in the rest of the issues.

I think you got the error in your first trial.
That is because gazebo downloads models in the first time and fails to launch baxter gazebo plugins correctly.
Can you try to relaunch again? and check rostopic hz /robot/joint_states?

pipothy · 2018-04-18T15:08:20Z

Hi,

In short, yep, you're correct! Launching the world once, it failed in the usual way. But then, closing that down and relaunching the world resulted in it working.

Sorry for the trivial issue, but thanks so much for your help!

sxwgit · 2019-03-18T05:58:10Z

Hello, I meet the same error.
I relaunch the world ,just like

./baxter.sh sim
roslaunch baxter_gazebo baxter_world.launch
ctrl+z
roslaunch baxter_gazebo baxter_world.launch

I get the info

[ INFO] [1552887561.104179646, 21.821000000]: Simulator is loaded and started successfully

But it didn't solve the problem, and the same error still occurred.
Would you mind tell me how you solved this problem?
Best regards.

knorth55 · 2019-03-18T06:08:27Z

@sxwgit
Please do not use Ctrl + Z.
First launch should take a long time, so please wait.
After first launching, you need to kill all gazebo process by Ctrl + C, and launch the same file again.

sxwgit · 2019-03-18T06:39:43Z

@knorth55
Thank you very much for your kind help.
I follow your method:

./baxter.sh sim
roslaunch baxter_gazebo baxter_world.launch
# waited about 5 mins
ctrl + c
roslaunch baxter_gazebo baxter_world.launch

and in a new terminal, I run the code:

 ./baxter.sh sim
 rosrun baxter_examples joint_position_waypoints.py -l right

Unfortunately, the error still occurs.
Do you know any other solutions, thank you very much for your answer and best regards.

sxwgit · 2019-03-18T07:10:13Z

I reinstalled the related librarys and found that the problem was solved.
Although I still don't know the cause of the error, it is still very happy to solve it successfully.：）！

yipliu · 2020-11-03T08:10:18Z

@sxwgit I want to know how to reinstall?

sometime just restart your PC can resolve your problem

I used to run Baxter very fast and without problems in Kinetic. But since I updated to noetic, I consistently get a slowdown; including using the real robot. I cannot figure out what I time out so much.I have updated my repo's to reflect python3 updates in print, exceptions, range, imports, etc...

Any generic clues about the slowdown due to a switch in noetic are appreciated.

Rawbotic · 2023-04-28T04:32:09Z

noetic,kind of same problem!

Rawbotic · 2023-04-28T04:32:30Z

real robot

ShawnZhou997 · 2024-11-19T03:32:10Z

Hi, all. I've solved this by recorrecting my baxter.sh file in the line of you_ip="192.168.x.xxx" or your_hostname="xxxx".
This happens after my Internet changed.
Hope this works for you.
