random_numbers

This branch has been ported to ROS 2.0

This library contains wrappers for generating floating point values, integers, quaternions using boost libraries.

Build Status

ros2
master (ROS1)

Features

New: you can pass in a custom random number generator seed to allow optional deterministic behavior during debugging, testing, etc. using the secondary constructor.
