2016-03-23 03:14:34 -0500 | asked a question | Is it possible to use more than one client library in the same workspace? I purchased a book that uses the python client library on ROS Indigo on Ubuntu 14.04. I would like to follow the code examples in the book and test them in my catkin workspace; then I would like to convert the python code examples to the Julia client library and test them in Julia. Should I/can I have the python code files and the Julia code files in the same catkin workspace, or should I have the different client libraries in separate catkin workspaces? |

The book states: "The latest version of Ubuntu is 12.04 (Precise) and the latest version of ROS is Fuerte.

2014-04-20 12:49:43 -0500 | marked best answer | How to replace old ROS Turtle version with ROS Fuerte installation I have the "old" ROS Turtle version installed on 64 bit Ubuntu 10.04 from long ago. Do I need to remove the ROS Turtle version before installing ROS Fuerte? If so, where may I find instructions to cleanly remove all ROS Turtle so I can install ROS Fuerte in a clean environment. I'm fairly new to ROS. When you write "just source the setup.sh of the new installation". what do you mean by that?! Could you just give me exact steps to execute? Please verify that your answer implies I'm able to switch back and forth between ROS Turtle, ROS Electric and ROS Fuerte without any version interfering with the other? (so in that case, uninstalling Turtle is not necessary) Thanks |

2014-04-20 06:51:51 -0500 | marked best answer | How do I solve Fuerte overlay creation problem? Using Ubuntu Precise 64 bit. Installation of Fuerte stopped cleanly at: Processing triggers for python-support ... SO HERE"S THE PROBLEM when I try to do the overlay: What to do? Apparently, one should not combine pip and apt on Ubuntu, and preferably not use pip on Ubuntu since pip is for non-Ubuntu. How do I uninstall an old vcstools installation under Ubuntu Precise? (sudo pip uninstall rosinstall vcstools rospkg ---------does not work)- I installed (DID NOT USE EASY_INSTALL)using the instructions at http://ros.org/wiki/fuerte/Installation/Ubuntu -----THIS USES APT...and I am not supposed to combine apt with pip. pip needs to be installed, but I should not use it according to TullyFoote. Concerning "you did not tell us the error"...., what error are you taking about?! The "error", DistributionNotFound: rosinstall==0.6.16 is listed above......if you are referring to errors using pip....I NEVER USED PIP. I'd rather use apt to uninstall rosinstall, vcstools, and instead of messing with the system manually. It seems if I installed using apt, then I should be able to uninstall using apt, right?! Can anyone tell me how to uninstall rosinstall, vcstools and rospkg using apt under Ubuntu Precise? (I never touched easy_install or pip) |

I understand how I must create a mesh of a threaded ball screw hex nut and a mesh of a threaded ball screw shaft, but how would I connect them joint-wise? How do I make the threaded bolt shaft turn to move the nut? Is it necessary to do this as a plugin, and if not, would it be better to do it as a plugin as an easily distributable example for others?
