HEBI Robotics Wins NASA Grant for Miniaturized Space Actuators
The Carnegie Mellon spinout will develop high-torque modular components for CubeSats through 2026.
Pittsburgh-based HEBI Robotics has been awarded a NASA Small Business Innovation Research (SBIR) Phase I contract to develop miniaturized, high-torque density modular actuators. The project, slated to run through December 2026, aims to provide flexible hardware for SmallSats, CubeSats, and other space-limited environments where traditional components often lack necessary versatility.
The Phase I award focuses on exploring the actuation trade space to package high-torque density motors and gearbox combinations into a small, mission-ready form factor. This effort builds on HEBI’s existing relationship with the space agency; the company previously secured a Phase II SBIR contract from NASA valued at $850,000 to develop actuation hardware specifically for harsh environments in Low Earth Orbit (LEO) and Geostationary Orbit (GEO).
The Modular Approach
HEBI Robotics is a spinout from the Carnegie Mellon University Biorobotics Lab. The company specializes in "Lego-like" modular actuation hardware and software, creating a platform that allows robotic systems to be designed and tested terrestrially before being transferred to space-rated hardware. This modularity is central to their strategy of simplifying the deployment of complex robotic systems in unpredictable environments.
Industry Implications
As the space sector undergoes rapid commercialization, the demand for affordable and scalable robotic systems has intensified. Small satellites are currently constrained by strict size and weight limits, which often restrict their manipulation capabilities. By miniaturizing high-torque actuators, HEBI is enabling more sophisticated robotic functions within these tight constraints, potentially lowering the barrier to entry for advanced space robotics.
"With space becoming increasingly commercialized, there is real demand for affordable, versatile, and scalable mass-production of robotic systems that can function in difficult environments," said Andrew Willig, HEBI’s director of hardware, according to The Robot Report.
Beyond Orbit
While the current grant focuses on NASA's space requirements, the company views the technology as having significant terrestrial applications. Willig noted that the lessons learned from the rigors of space apply to Earth, stating that rugged, easy-to-use systems are of interest to anyone deploying modular hardware in dangerous field environments.
Moving forward, the project will focus on refining the motor and gearbox combinations to ensure they meet the stringent requirements of space missions. The industry will be watching to see if these miniaturized components can successfully bridge the gap between low-cost hobbyist servos and the prohibitively expensive custom systems typically used in space exploration.
