## 1. Introduction
Mobile Robot Programming Toolkit (MRPT) provides C++ libraries aimed at researchers
in mobile robotics and computer vision. Libraries include [SLAM solutions](https://www.mrpt.org/List_of_SLAM_algorithms), [2D and 3D spatial transformations](https://www.mrpt.org/tutorials/programming/maths-and-geometry/2d_3d_geometry/), [SE(2)/SE(3) Lie groups](https://ingmec.ual.es/~jlblanco/papers/jlblanco2010geometry3D_techrep.pdf),
[probability density functions (pdfs)](https://docs.mrpt.org/reference/latest/class_mrpt_math_CProbabilityDensityFunction.html) over points, landmarks, poses and maps,
Bayesian inference ([Kalman filters](https://www.mrpt.org/Kalman_Filters), [particle filters](https://www.mrpt.org/tutorials/programming/statistics-and-bayes-filtering/particle_filters/)), [image processing](https://www.mrpt.org/tutorials/programming/images-image-processing-camera-models/), [obstacle avoidance](https://www.mrpt.org/Obstacle_avoidance), [etc](https://reference.mrpt.org/devel/modules.html).
MRPT also provides GUI apps for [Stereo camera calibration](https://www.mrpt.org/list-of-mrpt-apps/application-kinect-stereo-calib/), [dataset inspection](https://www.mrpt.org/list-of-mrpt-apps/rawlogviewer/),
and [much more](https://www.mrpt.org/list-of-mrpt-apps/).

## 3. Install
### 3.1. Ubuntu
See [this PPA](https://launchpad.net/~joseluisblancoc/+archive/ubuntu/mrpt) for nightly builds from the `develop` branch, or [this one](https://launchpad.net/~joseluisblancoc/+archive/ubuntu/mrpt-stable) for stable releases.
sudo add-apt-repository ppa:joseluisblancoc/mrpt # develop branch
#sudo add-apt-repository ppa:joseluisblancoc/mrpt-stable # master (stable releases) branch
sudo apt install libmrpt-dev mrpt-apps
Supported distributions:
* Ubuntu 18.04 LTS (Bionic), Ubuntu 20.04 LTS (Focal), or newer.
### 3.2. Build from sources
See [build documentation](https://docs.mrpt.org/reference/latest/compiling.html) ([source](doc/source/compiling.rst)).
### 3.3. Windows precompiled versions
Executables (`.exe`s and `.dll`s) and development libraries (`.h`s and `.lib`s) included:
[Nightly built Windows installer](https://github.com/MRPT/mrpt/releases/tag/Windows-nightly-builds)
### 3.4. As a ROS1/ROS2 package
MRPT is also shipped as a ros1 & ros2 package named `mrpt2`, so it can be installed via:
```bash
sudo apt install ros-$ROS_DISTRO-mrpt2
```
