NASA has released their CLARAty framework for robotics to the public for download.
JPL Robotics: News

CLARAty is an integrated framework for reusable robotic software. It defines interfaces for common robotic functionality and integrates multiple implementations of any given functionality. Examples of such capabilities include pose estimation, navigation, locomotion and planning. In addition to supporting multiple algorithms, it provides adaptations to multiple robotic platforms. CLARAty development was primarily funded by the Mars Technology Program and it serves as the integration environment for the program’s rover technology developments.
