Introduction

Pronto is an efficient, versatile and modular EKF state estimator for both proprioceptive (inertial, kinematics) and exteroceptive (LIDAR, camera) sensor fusion. It has been used with a variety of inputs from sensors such as IMUs (Microstrain, KVH, XSense), LIDAR (Hokuyo, Velodyne), cameras (Carnegie Robotics Multisense SL, Intel RealSense) and joint kinematics.

Legged Robots

Pronto provided the state estimate that was used by MIT DRC team in the DARPA Robotics Challenge to estimate the position and motion of the Boston Dynamics Atlas robot.

Pronto on Atlas

Since then, it has been adapted to estimate the motion of the NASA Valkyrie robot at the University of Edinburgh, the HyQ quadruped robot at the Istituto Italiano di Tecnologia, and the ANYmal quadruped robot at the University of Oxford.

Pronto on HyQ

Micro Aerial Vehicles

Pronto was originally developed for Micro Aerial Vehicle state estimation. The modules specific to MAVs (e.g., altimeter, GPS) are not currently supported.

Software Overview

The algorithms (and their ROS wrappers) are written in C/C++ and organized as catkin packages. The repository consists of the following main modules:

pronto_core: core libraries that implment the filter, the state and basic measurement modules (e.g., IMU, pose update)
pronto_biped leg odometry measurement modules for humanoid robots (tested on Atlas and Valkyrie)
pronto_quadruped leg odometry libraries for a quadruped robot (tested on HyQ and ANYmal)
pronto_quadruped_commons abstract interfaces to perform leg odometry on a quadruped robot. This is a fork of the iit_commons package (see here).
*_ros ROS wrappers of the above modules
other support packages for filtering

Dependencies

Pronto depends on Eigen and Boost

System Requirements

The target operating system is Ubuntu 18.04 equipped with ROS Melodic.
Other versions of Ubuntu/ROS might work but they are not actively supported or tested.

Building the Code

Pronto is organized as a collection of catkin packages. To build the code, just run catkin build followed by the name of the packages you are interested to build.

Robot Implementation Example

To learn how to use Pronto on your robot, you can have a look at this repository, which contains a full implementation on the ANYmal quadruped robot.
