221e MULTISENSOR INERTIAL CHAMALEON V2 DRIVER FOR ROS

The official ROS driver for the 221e Multisensor InerTial CHamaleon (MITCH) V2 device.

Package available for:

• ROS Noetic - Ubuntu 20.04;
• ROS Noetic - Windows 10.

1 - Installation

Step 1 : Install the ROS distribution

a) Ubuntu:

• Install ROS Noetic on Ubuntu 20.04;

b) Windows:

• Install ROS Noetic on Windows 10;

If you are exploiting Windows, we assume you are using Microsoft Visual Studio 2019. Remember to

• include the “Desktop development with C++” workload;
• in the Individual Components, select “Windows 10 SDK”.

Moreover, remember to start your installation routine from the ROS command short cut.

Step 2: Install lib221e

lib221e is the C++ library for the 221e Communication Protocol. Follow the installation instructions available here.

You can use git from Command Line. Otherwise, several free and commercial GUI tools are available. E.g., for the Windows platform, you can download a GUI from here.

In the same way, in Windows, you can install your library via Visual Studio [installed in step 1(b)]. A possible installation procedure follows:

• open Visual Studio with administrator privileges;
• choose to open up your library from your local folder;
• open the Developer Command Prompt from Visual Studio-->Tools-->Command Line ;
• launch cmake .. ;
• launch cmake --build . --target INSTALL --config Release .

Step 3 : Create a Catkin Workspace

a) Ubuntu:

Open a terminal. From the

``` directory:


```sh
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/
$ catkin_init_workspace
$ echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
$ source ~/.bashrc

Other details are available here.

b) Windows:

Open your ROS short cut terminal. In your

``` directory:


```sh
$ mkdir c:\catkin_ws\src
$ cd c:\catkin_ws
$ catkin_make
$ devel\setup.bat

Other details are available here.

You can decide to locate your workspace in other directories.

If you need the Ninja build tool, go to the releases page and download a suitable binary for Windows. Place

``` in a suitable spot, e.g., 
```C:\Ninja
```. Make sure that CMake can find 
```ninja.exe
``` by adding 
```C:\Ninja
``` to your 
```%PATH%
```.

***Step 4: Clone mitch_v2_driver in your Catkin Workspace

a) Ubuntu:

```sh
$ cd ~/catkin_ws/src/
$ git clone https://github.com/221eROS/mitch_v2_driver.git
$ catkin_make

b) Windows:

$ cd c:\catkin_ws\src
$ git clone https://github.com/221eROS/mitch_v2_driver.git
$ cd ..
$ catkin_make

2 - ROS for Windows: additional tips for Visual Studio 2019 [No mandatory!]

• We suppose you have already installed Visual Studio 2019in step 1(b);
• From the ROS shortcut of Step 1(b), enter devenv to start your Visual Studio IDE;
• Choose to open up your catkin workspace from your local folder;
• As Visual Studio is using different settings for CMake projects, we need to configure the CMake file. Thus, click Project --> CMake Settings for Project and edit the JSON version of your Cmake settings file as follows:

```sh { “configurations”: [ { “name”: “x64-Debug”, “generator”: “Ninja”, “configurationType”: “RelWithDebInfo”, “inheritEnvironments”: [ “msvc_x64_x64” ],
