Example Programs and Custom Programs are not working.

[Eash 0]

A new issue has risen. The issue is running the example programs, as none of the example programs work even after using the "enable" command.

$ rosrun intera_interface enable_robot.py -e

For example the " rosrun intera_examples joint_torque_springs.py " example does not move the robot to a "neutral pose" or even the " rosrun intera_examples camera_display.py " the terminal returns with

splay.py
Initializing node... 
[WARN] [WallTime: 1484625635.265185] Timed out waiting for command acknowlegment...
[WARN] [WallTime: 1484625640.309822] Timed out waiting for node interface valid...
[ERROR] [WallTime: 1484625640.310784] Failed to stop right_hand_camera from streaming on this robot. Unable to start streaming from head_camera
[INFO] [WallTime: 1484625640.319965] Camera_display node running. Ctrl-c to quit

I am able to get the joint states but none of the example code work. Do you know why this happening?

I am not too sure what the problem was, however, I connected the robot via router connection (as I previously had it as a direct connection) and enabled auto ethernet (in Unbuntu) and the examples seem to work now.

That's great Eash.  

Our experience on this end has shown that the router connection is the easiest and most straight forward way of connecting your robot to the work station.

Hey, 

i'm new to ros sdk.  

i have a problem with the "enable". 

when i use the command:[ $ rosrun intera_interface enable_robot.py -e ]

i get the error: package 'intera-interface' not found. 

 

Did i fotgot something?

It is probably only a trifle.

Hi Sina,

Make sure you have followed the instructions from the workstation setup guide: http://sdk.rethinkrobotics.com/intera/Workstation_Setup#Install_Intera_Robot_SDK

After you've downloaded all the SDK packages, run catkin_make and then re-source your environment by invoking ./intera.sh again. That will give you access to the intera_interface module.

Hope this helps!

Hi Ian, 

thanks for your help! 

I followed the instructions and have checked everything again. 

Another problem is i can't set the Fixed Frame as /base.

I get this error:  Fixed Frame  No ft data. Actual error: Fixed Frame [base] does not exist.

 

The enable_robot works now and the example programm run as well without an error message but sawyer does not move. 

Do you have any idea? 

Sina

Hi Sina,

I stumbled upon this while learning tf. Maybe it can solve your problem.

Hi StuweXY, 

unfortunately i could not solve my problem yet.  I have run the command roswtf and get the following error:

 

ERROR The following nodes should be connected but aren't:

• /rviz_1501573816403560019->/rosout (/rosout)
• /base_to_world->/rviz_1501573816403560019 (/tf_static)
• /robot_ref_publisher->/rviz_1501573816403560019 (/tf)

• /robot_state_publisher->/rviz_1501573816403560019 (/tf)

 

Does anyone else have an idea?  -- Thanks!

I'm having the following issue as well although the robot and the PC are connected via a router with auto ethernet enabled. What else might cause this?

Hi Sina and Aykut,

After you catkin_make the software and ./intera.sh command, can you try the command below:

rostopic echo /robot/joint_states

Are you able to get the joint state?

I get the joint states, but the Time out error still exists. I cant seem to understand the issue.
