Abstract: A stereo camera pair may be used to determine deformation and/or strain on a member based on differences in calculated movement of the cameras that capture images. In some embodiments, a first camera may be mounted to a first end of a member and a second camera may be mounted to a second end of the member opposite the first end. As the member bends, twists, or deforms in other ways, the deformation may be detectable based on differences in images captured by the first and second camera. This data may be used to detect possible wear or damage to the member, as a control input to a vehicle to reduce possible wear or damage to the member, as a prompt to initiate maintenance or inspection of the member, and/or for other reasons.

Abstract: Described are automated systems and methods for providing a simulated environment for robotic and/or real-time systems, such as unmanned vehicles, to perform full system simulations while also providing a system-wide code coverage assessment of the software associated with the robotic and/or real-time systems. The exemplary systems and methods can employ code coverage instrumented shared libraries to facilitate generation of code coverage information and one or more code coverage reports. The code coverage information and/or the code coverage report can quantify the effectiveness of the testing and can facilitate development of more comprehensive and efficient testing of the software.
