Multi-Platform, Scalable, and Modular Rover Flight Software Control Algorithms and Architectures for Autonomous ISRU Excavation, Transportation, and Deposition for Lunar Operations

ProtoInnovations, LLC proposes to continue the advancement and maturation of the Rover-Based Non-Prehensile Manipulation for Improved Mobility, Scientific Exploration and Terrain Shaping on Planetary Surfaces (RBNPM, NASA Phase II SBIR Contract #80NSSC19C0215) software control architecture and algorithms to enable robotic rovers to perform autonomous or semi-autonomous excavating, transporting, and depositing of lunar regolith during In-situ Resource Utilization (ISRU) missions. The central idea of this work is that robots can accomplish a multitude of terrain-altering tasks by intelligently sequencing active driving, steering motions, and/or dedicated tools for lunar surface operations. The RBNPM software architecture, is behavior-based and driven by multiple hierarchical layered primitives. Primitives are independent, modular, and generalizable, open-loop or closed-loop controllers that represent the smallest control element/module that can be implemented to produce a recognizable behavior or functionality. The overarching taxonomy of primitives exists at four levels of the architecture; mission, actions, operations, and signals. This new technology can amplify the performance of future NASA lunar surface systems for ISRU and construction operations in many ways. First, the modularity and configurability of the software architecture enables the primitives and software to be used on multiple platforms of different robotic configurations. This unique feature will allow for more standardization for future surface systems and provide new capability in space robotics software for NASA as well as for commercial space companies. Second, the architecture is controller-centric which enables real-time flexibility to achieve multiple operational objectives for increased safety, efficiency, or capability that can be selected and configured autonomously or by teleoperators, ideal for complex missions on the lunar surface.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
