2017-07-17 02:12:39 -0500 | marked best answer | Creating a ROS msg and srv - Tutorial Hi! I have the same problem as mentioned here: Error using rosmsg in "Creating msg and srv" Tutorial In section 2.2 of this tutorial when typing the command
I don't get
but
In the other thread the solution is: I should simply run:
But there I get the Error:
What do I do wrong. I changed the CMakeList.txt exactly as said in the tutorials and checked it a lot of times. And I put in
Can anybody help me out here? Thanks!! Edit: Here is the CMakeLists.txt (I removed the commented parts): And here the package.xml: |
2017-04-30 02:57:57 -0500 | marked best answer | Align endeffector of robot with vector Hi! as it says in the header I want to align my endeffector with a vector in space. In my case the z-axis of the EE should be aligned with the vector. This means that the x-, and y-axis are not specified. Right now I only manage to navigate the EE to a certain pose where the x-, y-, and z-axis are all determined. But sometimes the robot cannot reach this pose due to collisions or being out of reach. A simple turn around the z-axis would do the trick that the pose can be reached and still the goal "aligning with the vector" is achieved. My question: Is there an implementation in ROS or particularly in Moveit to automatically solve this? Best regards! Edit: My approach right now is to calculate the path to the target with angles from -180° till +180° in steps of 10° (All of them fullfill the requirement of alignment with the vector, but not all of them are possible for the robot). After that I know which angels are possible and can choose. But this takes some minutes as I have to set up the planner each time. So again the question: I'm looking for a way to this faster. And maybe there is an implementation? For example constraints for the target pose or something? |
2017-04-03 01:56:10 -0500 | marked best answer | Getting the joint values of a computed path to a pose goal Hi everybody, I'm using moveit with an UR5. The planner I use is the RRTConnectkConfigDefault-planner. The goal for the planner is a pose. My question is now: Is there a way to retrieve the joint values of the six axes of the computed goal. Maybe out of And second: Is there a way to get all possible IK-joints (all IK-solutions which also have no collisions) and choose the goal-joints out of them? Thanks in advance and regards! |
2017-03-31 16:03:57 -0500 | marked best answer | Location of move_group_interface for UR5 Hi! I'm trying to control an UR5 via MoveIt! in Indigo on a Linux Ubuntu 14.04 system. I did all the tutorials of ROS and Getting-Started with an UR5. And I do find the tutorial for Move Group Interface/C++ API. And there I understand the single points described. But I do not understand which file exactly I have to change here. Where can I find or where do I have to build this file? Is it somewhere in the catkin-workspace or somewhere in opt/ros/... Did I miss a tutorial at some point where this is described? Thanks in advance! |
2017-03-31 15:47:16 -0500 | marked best answer | Problems using descartes package Hi! I would like to use the descartes-package and I'm facing some issues. I'm using an UR5 with the moveit- and universal_robot package and want use the descarts-package parallel to that. To achieve that I just copied the code of the descartes-tutorial in the existing c++-API and adjusted it for the UR5. Until and so on until First I thought it's because it cannot reach the target pose, but I checked it for several poses which should be reachable and every time I get the same errors. Does somebody know how I could solve this? An additional question would be, whether the descartes-planner is considering the collision_scene of moveit? Thanks and regards EDIT: This is one of the trajectories I trying to reach. I think those could definitely be reached. |

Everything works fine, but since a while I get the following error when catkin_make my workspace. I did not knowingly change anything. Anybody knows where that does come from?

So sorry for asking it again, but I really have problems dealing with it and I'm trying for hours now. It seems like the answers for older releases of ROS don't work for Indigo or maybe just for me. :( I'd just want to install the descartes-package from source as there is no Can somebody help me out here please?

2015-10-21 07:28:25 -0500 | asked a question | roslaunch as executable Hi! Maybe this is more of an Linux-question instead of ROS. But anyway, maybe someone could help: I would like to know how I can build a single file which runs a roslaunch by double click on it. The goal is that someone could run my ros-project who is not familiar to any shell commands or anything regarding Linux. He would just click on one file and the whole thing just starts running. Is that possible? Edit: I already tried a bash file (test.sh) and in it is and gave the file the permission to execute ("Allow executing file as program" in file properties). But when I run it, nothing happens. Anybody knows what I'm doing wrong? |
