2015-09-11 08:28:17 -0500 | asked a question | How c++ subscribes float64 message published from rosserial Hi, I want to subscribe some data which is published from rosserial_arduino in cpp I coded like this in sketch This is for calculating odometry . As I can't use encoder, I have to publish constant velocity which I compute. I can check that the message is published well because I can watch the data with ' $ rostopic echo' so I coded with global function in .cpp file ##Like this There are tutorials about how to subscribe string message . But, I don't have idea if It is Float64 type. What is the form of subsribing float 64 type data ? |

2015-09-10 07:31:26 -0500 | commented answer | How to publish MAXON Encoder in EPOS2 70/10 for building "nav_msgs/Odometry" Thanks for your answer. actually , I have not known about odometry well just except the way to check position. For now.... I wonder how to get my encoder's ticks from epos2 to compute the velocity.... I also search this pkg ' http://wiki.ros.org/epos_hardware ' but, I don't know how to use |

2015-09-10 01:54:36 -0500 | asked a question | How to publish MAXON Encoder in EPOS2 70/10 for building "nav_msgs/Odometry" Hi, I'm learning ROS for graduating undergraduate course. I am following this Tutorial ' http://wiki.ros.org/navigation/Tutori... ' to make mobile robot. I already made teleoperation pkg , '/cmd_vel ', which spend the message to ' rosserial_arduino ' and control motor with key_board button. And next step, I want to build navigation. So I heard I have to make odometry and tf msg , which need a published 'Encoder data' . I have two MAXON motor ; the two controllers are EPOS2 70/10 . I have been googling how to publish encoder for using ' nav_msgs/Odometry ' but, I don't have idea ..... How to publish encoder data over ROS and subscribe it on using 'nav_msgs/Odometry' |

2015-05-31 01:38:04 -0500 | asked a question | Useing Rviz from Kinect v2 (xbox one) Hi, Please understand me If you don't understand my poor English. I'm begginer about Ros and I hope to use SLAM with depth cam , Kinect v2(xbox one) . I have done to install ' libfreenect2 '(from: https://github.com/code-iai/iai_kinect2 ) and checked camera data( Ir, depth, rpg) on commanding after than, I follow step and added checking list. but, There weren't any camera data in rviz . I think I need to do more somthing like making kinect node ? ? to spend rviz? but anyway I don't know about this well. What should I do? |
2015-05-30 08:14:52 -0500 | commented answer | How can I use Kinect v2 with ROS in Ubuntu 14.04 with libfreenect2 in ubuntu is different running it. I think because maybe work with cpu not graphic card ?? is It right? or not? after that. how can I use this data in ros rviz??? what is 'rosrun kinect2_bridge' for? Sorry to I bother you , I need more your help |

2015-05-30 08:06:00 -0500 | commented answer | How can I use Kinect v2 with ROS in Ubuntu 14.04 (2015-5-30) I understand what './Protonect' mean and I command in terminal $cd /libfreenect2/examples/protonect/bin after that ./Protonect cpu . than I could get screens(ir,depth,camera) . |
