2014-07-11 04:49:04 -0500 | commented answer | CodeRef macro not working in wiki I did make a new line for that code, but it seems that might not be the case (or just the website take effect with a delay, not in real time) as the page remains the same after I did the change. and when I come back a day later, everything is fine. |
2014-07-03 20:27:29 -0500 | asked a question | CodeRef macro not working in wiki http://wiki.ros.org/tf/Tutorials/Writ... So on this page, the CodeRef macro didn't work, and I've even tried to copy-paste the corresponding section in http://wiki.ros.org/WritingTutorials#... the exact same section which works on the "writing tutorials" page didn't work on "writing a tf listener" page. |

2014-04-12 03:12:57 -0500 | asked a question | " [opencv2] still active" when building Hydro from source UPDATE: After waiting long enough, the installation finishes. So I'll close this question. Thanks. I'm building ROS Hydro Desktop Full following this: http://wiki.ros.org/hydro/Installatio... and after I did this
and wait a while, the shell keeps out put this message I've did several search with google enter code hereand in answers.ros.org without any luck, only found that when other people build Hyrdo from source (like this guy http://rootf.blogspot.com/2013/05/how... ... ... ... [opencv2] still active [opencv2] still active [opencv2] Done. And I've tried this installation several times, it always stuck at the same place. I will leave the machine running for longer time and see if it will finish. I'm using Ubuntu 12.04.04 LTS 64bit version.' |
2014-01-28 17:25:20 -0500 | marked best answer | How to use multiple kinects on the same USB 2.0 bus Hi everybody, I got two questions about kinect driver (OpenNI,freeKinect under Ubuntu or even Kinect SDK under windows, what ever works. Kinect here refers to Kinect for Xbox, not Kinect for windows which is more expensive but support up to 4 kinect on same PC) Al though I got 3 independent USB 2.0 BUS, when I connect 2 Kinects to my PC, they always goes to the same USB BUS 1 is it possible to shut down Kinect_1 temporarily, to get IR streams from Kinect_2 on the same USB bus? For example, I want to do the 3D 360 degree scan, and I need 3 kinects to work together, but I only need them to work in 3 frames (which lasts about 0.1 second), each gives out 1 frame of point cloud. 2 is it possible to reduce the information that sent from kinect to PC, so that I can use several kinect at the same time without any one of them using up the bandwidth? For example, to do the 3D 360 degree scan, I only need 3 different point clouds from 3 different angles of the same object, but not anything else like RGB stream. part of my lsusb results(to make sure I really had 3 usb 2.0 bus on my laptop): |
2014-01-28 17:25:18 -0500 | marked best answer | How to force kinect to a certain USB 2.0 BUS I've got laptop with 4 usb BUS inside, 3 of them are usb 2.0. And I have 4 usb ports on side of my laptop, 3 of them are usb 2.0 PORT and one is 3.0 port. I want to connect 2 kinects to 2 of my usb 2.0 BUS, But no matter which usb 2.0 PORT I connect the Kinects to, they alwas goes in the same usb 2.0 BUS, hence I can only get data out of one Kinect, since one kinect will cost the whole bandwidth of a usb 2.0 BUS. here's my lsusb results: I want to force one kinect to use BUS 01 instead of BUS 02, but I don't know how. Any suggestions? Where can I find more information on that? |
2014-01-28 17:25:08 -0500 | marked best answer | how to define new message/generate new header in rosserial_arduino Hi, I kept searching through the wiki but this page was not created yet (http://www.ros.org/wiki/rosserial/Tutorials/Adding%20Other%20Messages) and I can't try it out myself, so I'm going to ask here. in this link(http://answers.ros.org/question/11023/rosserial-and-custom-message-cannot-load-package)brice rebsamen says there's a script generating new msg type for me, where is it? say, I want to define a new msg type new_msg::New, to publish it from PC to arduino. while I got New.h in package new_msg with the command "make" under the package, this New.h is not suitable for arduino liberary. I need a New.h file that tell arduino what the message looks like. What should I do? Thank you in advance! |
2014-01-28 17:24:56 -0500 | marked best answer | how to fix ros:Message error? I try to run Minority Report Interface in MIT Kinect Demos, and when I rosmake kgui, I got this error: /kgui/src/RosGlobals.h:293:21: error: ‘Message’ in namespace ‘ros’ does not name a type and I checked RosGlobals.h, it says(start from Row 293): I did a little search and find this might be the difference between diamondback and electric, does anybody know how to solve this? |
2014-01-28 17:24:49 -0500 | marked best answer | How to use mit-ros-pkg without ni? I try to use mit-ros-pkg (finger detection/minority report interface) under Ubunt11.10, ROS Electric, but it won't work. Since this package said in its doc that it would work under Ubuntu 10.04, ROS DiamondBack, So I installed these on another PC. But the package uses NI for kinect driver, and I can't download ni.rosinstall, the file does not exist anymore. I think the finger detection feature is pretty useful, so I want to know how to use this package under electric & openni? or, if it's too hard to transfer it to electric, please tell me how to use it |
2014-01-28 17:24:41 -0500 | marked best answer | how to check out from an svn that requires "callback_ssl_server_trust_prompt" ? I'm installing Kinect Demos for DiamondBack,follow the instruction here: http://www.ros.org/wiki/mit-ros-pkg/KinectDemos/dback and I get stucked on step 5: Check out the mit-ros-pkg code, as well as other needed libraries using rosinstall: I got error msgs like this So my question is, how to neglect this callback_ssl_server_trust_prompt and check out the svn anyway? Or, how to get this trust so that I can check out the svn? I searched and found this https://code.ros.org/trac/ros/ticket/3169 it says "mit-ros-pkg has a self-signed certificate, which means that SVN creates a prompt for checkout. You can override this in svn with '--non-interactive --trust-server-cert'. This doesn't seem like the right default option, but it would be nice to have an option in rosinstall that forces this. Otherwise we cannot rosdoc mit-ros-pkg w/o manually checking it out on every build machine " but rosinstall doesn't have the option of "--non-interactive --trust-server-cert" my OS is Ubuntu 10.04, with DiamondBack. Thanks! |
