2019-04-08 01:19:58 -0500 | marked best answer | dynamixel_controller manager wrong package prefix Hello, I'm working with the dynamixel MX-64AT servos. Using a Ubuntu 16.04 and ROS kinetic version 1.12.12 Up until now I had no problem to get them up and running. Then I switched computers and now I get an error message whenever I try to start the controller_manager. Weirdly this problem now also occurs on the computer that up until now I had never had any troubles with. Basically the error can be reproduced when following this tutorial : http://wiki.ros.org/dynamixel_control... I do have the baud rate and id set to the right values and also checked that the USB port has the correct read and write permissions. Also I read that it could be related to faulty cables, but I also changed all of them several times, so that shouldn't be the problem. Whenever I try to execute roslaunch my_dynamixel_tutorial controller_manager.launch I get these error messages saying something about a invalid response and wrong prefix error. Weirdly enough, sometimes it will still recognize both motors and be able to work with them. To me it sounds a bit as if something with the communication is going wrong, but to be honest I can't figure out, where it's going wrong. I would appreciate any help. Best Regards, B. |
