2015-01-23 19:07:28 -0500 | asked a question | time_from_start of JointTrajectory on RosMatlab Nice to meet you. I am Jun from Germany. I am using the RosMatlab I/O package released on january 2014. I am having problems when trying to publish a JointTrajectory from Matlab. Because I can’t find the way how to set “time_from_start”, it happens a publish error on Matlab now. Could you teach me how to set the“time_from_start” on RosMatlab? with the next code : node = rosmatlab.node('PublishTrajectory', [], [], 'rosIP', '127.0.0.1'); publisher = rosmatlab.publisher('Traj', 'trajectory_msgs/JointTrajectory', node); msg = rosmatlab.message('trajectory_msgs/JointTrajectory', node); po = rosmatlab.message('trajectory_msgs/JointTrajectoryPoint', node); p1 = msg.getPoints(); po.setTimeFromStart(1); p1.add(po); msg.setPoints(p1); publisher.publish(msg); If I run the above code, the below message comes on Matlab and can’t publish. No method 'setTimeFromStart' with matching signature found for class 'org.ros.internal.message.$Proxy27'. Error in JointTraj (line 27) po.setTimeFromStart(1); I would appreciate it very much if you could advise me anything. Best regards, Jun |

2015-01-12 20:25:50 -0500 | asked a question | How to publish PoseArray on RosMatlab Nice to meet you. I am Emily from Germany. I am using the RosMatlab I/O package released on january 2014. I am having problems when trying to publish a PoseArray from Matlab to Rviz. I can send the message from Matlab. But Rviz can’t display the PoseArray, because it doesn’t set the “frame_id” of header file. Unfortunately, I can’t fins the way how to set them on the below code. Could you teach me how to set the frame_id or header file on RosMatlab? with the next code : If I run the above code, the below message comes on the rviz and can’t display the posearray.. I would appreciate it very much if you could advise me anything. Best regards, Emily |
