2017-04-20 13:52:09 -0500 | marked best answer | Getting Matlab compiled libraries to work in ROS I have created a library (myImShow.h & myImShow.so files) from the Matlab library compiler. Later I have created a C++ program that calls the functions inside the library. I was able to add these libraries into a ROS package CMakeLists, compile and run the program with no errors only if I don't add the If I do add the I get the following error from the MCR
It seems that there is a conflict with ROS when trying to run both of the libraries together. Has anyone ever successfully add a library compiled by Matlab with ROS? |

2017-01-12 02:56:18 -0500 | asked a question | Transforming Euler angle to Quaternion Hello, I have a new inertial sensor that provides the orientation of the robot in RPY. I want to load the information in an sensors_msgs/Imu ROS message using: The problem is when the yaw changes from +pi to -pi, the quaternion angle also has a "jump" in the angle from w=-0.99 to w=0.99 How can I transform the angle correctly? Thanks, |
2016-11-01 02:18:07 -0500 | commented question | Dynamixel multiple motor speed controller Thanks a lot, it works. Is there a way to set the min angle limit to infinity? When publishing a positive value it turns non stop CCW (which is good), however, when publishing a negative value it stops after a serveral degrees ("At end MN True" appears in manager). Any ideas why? |

2016-10-31 09:03:30 -0500 | asked a question | Dynamixel Speed control / wheel (continuous rotation) mode Hi, I have started working with Dynamixel motors (RX-64), and I know that it is possible to use the motor in a continuous rotation (a.k.a wheel) mode. I can't seem to figure out how this should be done? Somewhere I found that if I set the motor's CW and CCW angles to 0, it should change to a speed controller, but I can't figure out how? I have tried calling a service of set_speed. In addition, can someone explain what does the values in the motor field in the tilt.yaml file? There is init, min, max. I understand that it is something to do with the angles, but don't understand what. Thanks, |
