Authentication Required for Barrett WAM Arm Tutorial

asked 2017-08-16 10:29:09 -0500

Hi, I'm following the arm_navigation) tutorial for the Barrett WAM Arm, and I am stuck on the following lines:

$ rosws set barrett-ros-pkg --svn --version-new=25
$ rosws update sandbox/barrett-ros-pkg

When I attempt to run these commands, I am asked for authentication from the server. This is generally the error message I receive:

svn: OPTIONS of '': authorization failed: Could not authenticate to server: rejected Basic challenge (
Exception caught during install: Error processing 'sandbox/barrett-ros-pkg' : [sandbox/barrett-ros-pkg] Checkout of version 25 into /home/brtfrodo314/fuerte_workspace/sandbox/barrett-ros-pkg failed.

ERROR in config: Error processing 'sandbox/barrett-ros-pkg' : [sandbox/barrett-ros-pkg] Checkout of version 25 into /home/brtfrodo314/fuerte_workspace/sandbox/barrett-ros-pkg failed.

I've attempted to contact Barrett Technologies but they have been largely unresponsive. I have also tried every solution online for the server authentication issue, such as deleting my GNOME keyring and changing http to https. Nothing works. Is there no other source for this package? Because if not, then the whole tutorial is meaningless.

There is one possibility that I have found: Someone created a catkinized version of the package: However, I'm not sure how to re-adapt it for rosbuild. What can I possibly do?

Unless you purchased an actual Barrett WAM Arm, you may not hear back from Barrett. I don't think that they'd be willing to give someone access to their repositories unless they bought one of their products. I have found them to be quite responsive (if you have a service number).

My company actually did purchase the arm. Barrett support told me that the tutorial is outdated and that I should use the catkin version of the package. But the arm_navigation package seems to have a lot of dependencies relying on rosbuild and/or ROS Fuerte, which isn't compatible with catkin.

Were you able to get access?

So far, no, they haven't provided me access... :(

Looks like my only option is MoveIt, which has no documentation for Barrett WAM.
