Sorry if this is a noob question, I'm just getting started with ROS / MoveIt.

Let's say you have a robot arm, and that there will always be an S-shaped object that a robot arm should move around. What should you do so that the robot arm navigate around this object?

Thank you for the detailed explanation, this is so helpful!

Hi! Sorry for the basic question, I'm new to ROS and just having trouble with all the different concepts.

https://github.com/SintefManufacturin... This library provides Python access to a UR arm.

https://github.com/UniversalRobots/Un... This library provides a ROS driver for a UR arm.

Why do you need the driver? It seems like everyone uses the driver, but why can't you just use the library? What's the difference? Is it just to have access to MoveIt?

You're right, just edited my question!

Thanks! Sorry I edited my comment but not sure if you saw the edit. Does this mean that if for one node, you use a Multi

Thanks! I don't need to access the default callback group, I just didn't know where to look to see what the default call

http://docs.ros2.org/latest/api/rclpy... I saw in the definition for action clients that if no callback group was defined that the node's default callback group is used. How can I find what this is?

@SmallJoeMan Actually would you be open to switching to a single threaded executor to see what happens?

Got it, thanks for the info! That helps a lot. Realized my initial question was not framed properly. That's interesting

Default callback group? http://docs.ros2.org/latest/api/rclpy/api/actions.html I saw in the definition for action client

Got it, thanks for the info! That addresses my question. Interesting that it works even though you're not using Reentran

I meant how can I make it so that the action server can accept new callbacks even while it is still processing another c

Are action callbacks blocking? Let's say an action Fibonnaci takes 5 minutes to complete. If Fibonacci is called twice i

@jacobperron Thanks! Sorry if this is a dumb question, but is the wait blocking? Does this mean that ActionFromService c

How should I call two actions from the same client? Let's say I'm given two numbers, a and b, and I need to return the F
