2019-09-20 02:41:17 -0500 marked best answer Can we directly install ROS Kinetic packages on PC running Ubuntu 16.04 without installing ROS Kinetic on that PC ?

Hi, I'm new to the ROS and Ubuntu world.While I was trying to install ROS Kinetic on PC running Ubuntu 16.04 a new question arose to my mind that "whether it is always necessary to install first the ROS Kinetic on the PC running Ubuntu 16.04 or we can directly install ROS Kinetic packages like TurtleSim,Catkin,etc. on the PC using the command 'sudo apt-get install ros-kinetic-[PACKAGE_NAME]' without installing the ROS on PC(which will include some of the packages already in it)."

And if it is possible to directly install packages on the PC running Ubuntu without completely installing ROS on PC,will we be able to used all the commands of the ROS like roscore,rosrun,rospack,source the environment,catkin,etc. in that PC.

Any help in these question will be highly appreciated.

2017-03-06 02:11:11 -0500 asked a question Which packages can be used for running the USB Camera in ROS Kinetic ?

Hi, I'm using ROS Kinetic on Ubuntu 16.04 in my PC.I want to connect the USB Camera to PC and to stream video/image capture from camera using the ROS on PC.I tried using package like usb_cam available on the ROS website but it shows me error of yaml calibration file not found.

And also when I searched on Google about the package. I found that it is compatible about ROS Indigo only.

So,can someone suggest me the way in which I can connect camera to the PC and stream video on PC using ROS ?

Camera Details (from lsusb command): Microdia PC USB Camera (SN9C201 + OV7660)

ROS - Kinetic

OS - Ubuntu 16.04

2017-02-21 04:08:35 -0500 asked a question Is there any command in ROS for knowing the system dependencies of the ROS packages ?

Hi,

While I was reading on ROS packages,I came across that there are two kinds of dependencies.One is system dependencies and other is package dependencies.As we know that we can list the package dependencies using rospack command and if we want to list the system dependencies then whether there exists any command which list all the system dependencies of the package in similar way like the rospack command.

Any help in these question will be highly appreciated.

2017-02-21 03:33:04 -0500 marked best answer Does we always have to first build catkin_workspace and then only build the catkin_package present in the src of catkin_workspace ?

Hi, I was reading ROS tutorials page on creating and building package in which I came across how to build the ROS packages. In the page it is shown that first the author has build the catkin workspace using catkin_make command and then he/her has build the beginner_tutorials package present in the src directory of the catkin_ws using the same command. So I want to know that whether we always I have to follow the above mention steps or we can directly build the catkin packages as shown in the tutorials inside the catkin_ws.
