2017-01-12 12:18:37 -0500 commented question roscore not installed after installing ros-kinetic-desktop-full

I got a working system again by performing sudo apt-get install python-ros*. I still don't really know what happened, but at least it's working.

2017-01-12 12:06:34 -0500 asked a question roscore not installed after installing ros-kinetic-desktop-full

I just installed a fresh sudo apt-get install ros-kinetic-desktop-fulland it looks like it installed the majority of ros tools, however I'm missing at least roscore and rosrun.

I can download them individually with sudo apt-get install roslaunch-python and sudo apt-get install rosbash But now it seems that rospack can't find any of my packages.

I don't know if I'm doing anything wrong, but I've successfully done this dozens of times without any problems.

Any ideas why ros-kinetic-desktop-full isn't giving me the full complement of ros tools?

Thanks

Do you happen to be using a USB 3.0 port? I know that XTION devices have to undergo a firmware upgrade in order to work on a USB 3.0 port. (even the USB 2.0 devices)

Some more information about this is at https://github.com/nh2/asus-xtion-fix

2016-03-24 13:12:18 -0500 asked a question uvc_camera mjpeg support

Hello, I just got an ELP-USBFHD01M-L21 UVC webcam I want to use with ROS. It supports 120 FPS with 640x480 resolution via mjpeg encoding, which I have confirmed with guvcview. However, I cannot get either libuvc_camera or uvc_camera to support this encoding, and I'm forced to use the 30 fps supported by yuyv encoding.

Is there a webcam driver for ROS that supports mjpeg, or any way I can modify libuvc_camera to recognize this encoding? It seems that mjpeg is not recognized, and defaults to yuyv.

I'm using ROS indigo on 14.04 ubuntu.

2016-01-23 10:12:53 -0500 answered a question Programmatic way to stop roslaunch

If you're using C++ you can use system("pkill roslaunch") in your node to kill the roslaunch from the system level. I use it for monte carlo simulations with Gazebo).

2016-01-21 22:09:55 -0500 answered a question just copying catkin_ws/src from other,and catkin_make causes 'can't find *.h'

It looks to me like a custom message isn't being built. Check to make sure that your IOWrapper package CMakeLists.txt has a dependency on lsd_slam_viewer_generate_messages_cpp. Here is another question that explains how to properly build messages from separate packages.

2015-02-10 14:59:47 -0500 asked a question rosserial Imu.h Not complete

Hi, This is my first question I've ever asked here, so forgive me if this is stupid:

I am trying to publish Imu messages from an Arduino connected to an accelerometer/gyro. When I compile, I get this error:

In file included from ~/vo_ws/src/imu/firmware/imu.cpp:18:0:
~/vo_ws/build/imu/ros_lib/sensor_msgs/Imu.h:1:0: error: unterminated #ifndef
 #ifndef _ROS_sensor_msgs_Imu_h

I looked into this, and the Imu.h file in my ~/sketchbook/libraries/ros_lib folder is incomplete. It looks like this:

#ifndef _ROS_sensor_msgs_Imu_h
#define _ROS_sensor_msgs_Imu_h

#include <stdint.h>
#include <string.h>
#include <stdlib.h>
#include "ros/msg.h"
#include "std_msgs/Header.h"
#include "geometry_msgs/Quaternion.h"
#include "geometry_msgs/Vector3.h"

namespace sensor_msgs
{

  class Imu : public ros::Msg
  {
    public:
      std_msgs::Header header;
      geometry_msgs::Quaternion orientation;
      float orientation_covariance[9];
      geometry_msgs::Vector3 angular_velocity;
      float angular_velocity_covariance[9];
      geometry_msgs::Vector3 linear_acceleration;
      float linear_acceleration_covariance[9];

    Imu():
      header(),
      orientation(),

and that's the end. It seems to me that the file should have a lot more in it. I've tried deleting ros_lib and re-creating it with make_libraries.py a few times with no luck. Any ideas?
