2020-08-11 03:57:39 -0500 | marked best answer | Motor control using ROS, Epos2 and CANOpen Hello everyone, I happen to be stuck for a few days now by problems some of the forum's members apparently already encountered, whence this question. I hope the latter will not be considered as superfluous, and that it could prove to be helpful to others. My computer runs a 64-bit Debian GNU/Linux 10 (buster) OS, and ROS Noetic Ninjemys ( My current goal is to manage to send rotation speed commands to an AC motor equipped with a Hall sensor (similar to this model) through an EPOS2 70/10 electric drive, using the CANOpen communication protocol, and thus, the "ros_canopen" package. My problem is that I actually don't know where to start to achieve such objective. After some researches, I ended up trying to follow the steps proposed here on the forum. I was though not even able to complete the first stage, consisting in setting-up SocketCAN. I met indeed two issues:
Could you please give me a clue about how to overcome those problems ? An additional difficulty may come from the fact that I have chosen thus far to connect the EPOS2 controller to my computer using its USB output only. I do not employ any CAN-to-USB interface, simply because I do not have one to hand for now. Is such a device necessary to perform motor control ? Could you finally please recommend me a tutorial, or give me pieces of advice, regarding motor control using the "ros_canopen" package. Thanks a lot, regards, Julien. |

2020-07-06 02:16:51 -0500 | marked best answer | catkin_make could not find roslib Hello everyone, First of all, thank you for this amazingly helpful forum. I have been using ROS for a few months now, but I only decide to write a question here today. My computer runs a 64-bit Debian GNU/Linux 10 (buster) OS, and a version of ROS that, as far as I understand, corresponds to Melodic Morenia (though I am trying to conceive a data acquisition and control system using ROS, based on tools found within the ROS ecosystem, and on homemade packages (developed using C++). I would like now to make my system be able to control a motor using the CANOpen communication protocol, which led me to try to install the "ros_canopen" set of packages. However, I am currently not able to build these packages. My project's directory (named "autofleet") is located within a Catkin workspace, and corresponds besides to a Git repository. It contains a couple of homemade packages, along with some other packages (including the "ros_canopen" set) that have been defined as Git submodules of my superproject "autofleet". I am used to employ the The latter depends indeed on "pluginlib", which I had not cloned yet within my project. I hence did so, and then tried to build the appropriate packages of my Catkin workspace using the This is where I get confused, because I thought that "roslib" was part of the basic ROS installation, and I did not understand how Catkin / Cmake could not find the corresponding components in order to properly build the "pluginlib" package... Besides, running (more) |
