Hello everyone,

I have the following setup:

• The main thread which starts a ROS node with services, pubs, and subs
• A multiprocessing.Process which also should start an (anonymous) ROS node that has pubs and subs

So far so good. When I start (fork) the new process before calling rospy.init_node, everything works fine when I start from the command line.

However, when I start the application via roslaunch, I get the following error:

shutdown request: new node registered with same name

It looks like roslaunch/node enforces a new name in every node started as a subprocess. Any ideas how to circumvent the problem?

You should be able to run the tests also with the pytest runner. It doesn't matter if the test source code contains ROS

An alternative might be the internals of rqt_launch. It basically parses the XML-based configuration and is able to star

@jbeck28 Did you find a solution? I'm seeing a similar problem with my robot using IKFast. The adapter in the example co

You need to set service_request.ik_request.robot_state.is_diff = true;

Did you find anything? What did you choose?

@ash6r Did you find a solution for generic IK solvers?

My setup includes one robot controlled via Move It and additional robot-like machines which should be added at runtime, but not controlled via Move It.

I've read this discussion here Moveit Google Groups which states that multiple robots aren't supported with one planning scene. Instead, one might add the non-moving robot/object to the moving robots planning scene by hand/software.

Since the thread is from 2014, is this still information still up to date? Are there any better solutions than to add/remove the objects to the planning scene programmatically?

Thanks, Alex

Thank you for detailed answer. Indeed, I try to add the additional (CNC) machines as robots, so I can move their axes ar

Have you found a solution?

Have you found a workaround?

Just use Popen: import shlex from psutil import Popen # start node_process = Popen( shlex.split('rosrun foo bar') )

registered depth image and color image vs XYZRGB point cloud In my robot setup, I combine a 2D color camera with a ToF/3

In my case I needed to increase the queue size of point_cloud_xzyrgb: <param name="queue_size" value="10" />

Same here.

Hello everyone,

I'm currently working on a project picking bottles of different sizes from a shelf. For this purpose, I need an adaptive robot gripper. However, besides Robotiq, I can't find many gripper manufacturers.

Currently, I use the Robotiq Hand-E with custom fingers, but I need to modify the bottles for this work.

What I need:

• Gripper for grasping round and cubic objects (bottles)
• The bottle diameter is usually 50-100mm
• Ideally electric
• controlled via Modbus or I/O
• Payload up to 2-2.5kg

What I have found so far:

• Robotiq 2F-140 adaptive gripper - best solution, very pricey
• Festo Fin-Ray Effect Fingers + electric parallel gripper - relatively cheap, but no electric parallel grippers from Festo

Are there any other options on the market? And is really everyone using pneumatic grippers? I can't see that happening in an office/bar setting.

Thanks, Alex

After a bit of internet research I found a few additional options: ON-Robot RG2 and RG6 SAKE Robotics Gripper Adaptive

It looks like that. However, I already found a gripper that suits my needs, I will answer my own question shortly.
