Turtle Town Mac OS

Posted on  by

Box Turtle was released on March 2, 2010 and is the first ROS distribution release. Many of the stacks in the ROS system had their initial 1.0 release with this release, which required intensive user testing and on-robot testing.

Installation

Please see the installation instructions.

Platforms

ROS Box Turtle is primarily targeted at Ubuntu Hardy through Karmic releases, though it can also be installed on various Linux systems like Red Hat, Debian, and Gentoo. It can also be used on OSes like Mac OS X, though with more limited compatibility.

Stacks

Box Turtle provides over sixty ROS stacks divided into three variants:

  • base: Robot-generic, building block libraries, like the ROS navigation stack, as well as developer tools like rviz in the visualization stack.

  • pr2: Libraries and tools for the Willow Garage PR2 robot

  • pr2all: Experimental libraries for the Willow Garage PR2 robot, as well as ongoing research code.

base

Stacks in the base variant are generally very stable and consist mainly of robot-generic libraries, developer tools, and drivers for common hardware.

  • ROS

  • camera_drivers

  • common_msgs

  • common

  • diagnostics

  • driver_common

  • geometry

  • image_common

  • image_pipeline

  • imu_drivers

  • joystick_drivers

  • laser_drivers

  • laser_pipeline

  • navigation

  • physics_ode

  • robot_model

  • simulator_gazebo

  • simulator_stage

  • slam_gmapping

  • sound_drivers

  • vision_opencv

  • visualization_common

  • visualization

pr2

The pr2 variant is intended for users of the PR2 robot and mainly consists of stable, PR2-specific libraries. In the future, some of these libraries may become robot-generic.

  • image_transport_plugins

  • pr2_apps

  • pr2_common

  • pr2_controllers

  • pr2_ethercat_drivers

  • pr2_gui

  • pr2_mechanism

  • pr2_power_drivers

  • pr2_robot

  • pr2_simulator

  • web_interface

  • wifi_drivers

pr2all

The following stacks are provided in the 'pr2all' variant. These stacks are generally unstable and are very volatile. Subsequent ROS distributions may include these stacks in the 'base', 'pr2' or other variants as they stabilize.

  • arm_navigation

  • collision_environment

  • kinematics

  • motion_planners

  • motion_planning_common

  • motion_planning_environment

  • motion_planning_visualization

  • pr2_apps

  • pr2_arm_navigation

  • pr2_arm_navigation_apps

  • pr2_arm_navigation_tests

  • pr2_calibration

  • pr2_common_actions

  • pr2_doors

  • executive_python

  • pr2_kinematics

  • pr2_kinematics_with_constraints

  • pr2_navigation

  • pr2_navigation_apps

  • pr2_plugs

Python on a Macintosh running Mac OS X is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.

4.1. Getting and Installing MacPython¶

Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python 3 from the Pythonwebsite (https://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.

What you get after installing is a number of things:

  • A Python3.9 folder in your Applications folder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; and PythonLauncher, which handles double-clicking Pythonscripts from the Finder.

  • A framework /Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.

The Apple-provided build of Python is installed in/System/Library/Frameworks/Python.framework and /usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.

IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.

If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.

4.1.1. How to run a Python script¶

Your best way to get started with Python on Mac OS X is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.

If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. Mac OS X comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim-dev.github.io/macvim/) and Aquamacs(http://aquamacs.org/).

To run your script from the Terminal window you must make sure that/usr/local/bin is in your shell search path.

To run your script from the Finder you have two options:

  • Drag it to PythonLauncher

  • Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.

4.1.2. Running scripts with a GUI¶

With older versions of Python, there is one Mac OS X quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.

With Python 3.9, you can use either python or pythonw.

4.1.3. Configuration¶

Python on OS X honors all standard Unix environment variables such asPYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your .profile or.cshrc at startup. You need to create a file~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.

For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.

4.2. The IDE¶

MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttp://www.hashcollision.org/hkn/python/idle_intro/index.html.

4.3. Installing Additional Python Packages¶

There are several methods to install additional Python packages:

  • Packages can be installed via the standard Python distutils mode (pythonsetup.pyinstall).

  • Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.

4.4. GUI Programming on the Mac¶

There are several options for building GUI applications on the Mac with Python.

PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pypi.org/project/pyobjc/.

Turtle Town Mac Os X

The standard Python GUI toolkit is tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.

wxPython is another popular cross-platform GUI toolkit that runs natively onMac OS X. Packages and documentation are available from https://www.wxpython.org.

PyQt is another popular cross-platform GUI toolkit that runs natively on MacOS X. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.

4.5. Distributing Python Applications on the Mac¶

The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.

4.6. Other Resources¶
