Recognizing the need to write reactor-based GUI applications, the ACE community has created several reactor extensions for use with X Window System. Each of these extends the ACE_Select_Reactor to work with a specific toolkit.

The Mobile Robot Programming Toolkit (MRPT) is an extensive, cross-platform, and open source C++ library aimed to help robotics researchers to design and implement algorithms in the fields of Simultaneous Localization and Mapping (SLAM), computer vision, and motion planning (obstacle avoidance).
