Protoinnovations, LLC¶
Academic spinoff becomes NASA's primary commercial rover mobility R&D partner. FO project validates core wheel-soil physics for VIPER/Artemis rovers.
Last updated: Session 71, 2026-04-07
Summary¶
Protoinnovations, LLC (Pittsburgh, PA) is a robotics spinoff from the CMU Field Robotics Center, founded by professor Dimi Apostolopoulos to commercialize his academic rover mobility research. The FO project 158499 tested wheel-regolith interaction under lunar gravity conditions during parabolic flight, achieving TRL 6→8 — one of the strongest TRL advances in the FO portfolio. The company has tested VIPER lunar rover wheels (25 miles over lunar simulant confirmed by NASA article) and maintains a 14-year, $19-20M NASA contract relationship. This is the textbook archetype of academic spinoff becoming a specialized government contractor.
Outcome category: Active Maturation / Specialist R&D — FO validates core wheel-soil physics knowledge; Protoinnovations is NASA's primary commercial rover mobility R&D partner, feeding VIPER/Artemis rover development.
Confidence: confirmed (NASA VIPER article, USASpending, 2025 Chandler publication)
Archetype: Academic spinoff → specialized NASA contractor
FO Project¶
| Field | Detail |
|---|---|
| Project ID | 158499 |
| Title | Wheel-Regolith Interactions |
| Period | 2024-02-01 – 2025-09-30 |
| TRL | 6→8 (strong advance) |
| TX area | TX04.2.2: Above-Surface Mobility |
| PI | (none listed) |
| Co-Investigators | Arjun Agarwal, Dimi Apostolopoulos, Samuel Chandler |
Technology: Parabolic flight testing of wheel-regolith interaction for rover mobility under lunar gravity. Measurements include drawbar pull force and slope performance in 1/6-g. This is fundamental terramechanics data that underpins rover traction control and path-planning algorithms — the kind of measurement you cannot simulate accurately without the correct gravity environment.
Why parabolic flight matters here: Wheel-soil interaction is strongly gravity-dependent. Lab tests at 1-g systematically overstate traction. The 6→8 TRL jump indicates the parabolic data was decisive — the physics transferred to flight-like conditions.
Founding and Origin¶
Dimi Apostolopoulos is a professor at Carnegie Mellon's Field Robotics Center, one of the most productive field robotics labs in the world. He founded Protoinnovations as a commercial spinoff to carry his rover mobility research beyond academia. The company's core technical identity — wheel-terrain interaction, traction control, slip estimation — maps directly to his academic research program.
Samuel Chandler (co-I on this FO project) published a 2025 paper on lunar regolith physics and rover mobility, establishing that the academic-commercial pipeline remains active through the research team.
VIPER Connection¶
Protoinnovations has tested VIPER lunar rover wheels in their Pittsburgh sandbox facility. A NASA article confirmed 25 miles driven over lunar simulant in the Protoinnovations lab — substantial physical testing of the actual VIPER wheel design. This positions Protoinnovations as a technical contributor to the VIPER mission's wheel system validation, not just a study contractor.
EMBED Software in VIPER cFS: ProtoInnovations developed and integrated the EMBED app into the VIPER Core Flight System (cFS) — a proprioceptive, low-bandwidth slip and embedding estimation algorithm that detects when the rover risks high slip rates in loose regolith and initiates a stop command to prevent entrapment. This is not just test data contribution — ProtoInnovations' software is flight software on the rover itself.
VIPER was canceled in Sep 2024, then revived in Dec 2025 via Blue Origin CS-7 ($190M CLPS task order, late 2027 delivery). Blue Origin must first demonstrate its MK1 "Endurance" lander on a pathfinder mission (targeting late 2026) before NASA exercises the VIPER deployment option. ProtoInnovations' VIPER contributions remain relevant — the rover hardware and software were already built and tested before cancellation.
Tipping Point Award (Jul 2023)¶
$6.2M — "The Mobility Coordinator: An Onboard COTS Software Architecture for Sustainable, Safe, Efficient and Effective Lunar Surface Mobility Operations." This is separate from the FO project and SBIR portfolio. Awarded under NASA's 6th annual Tipping Point opportunity (Jul 25, 2023), total selections $150M across 11 companies.
The Mobility Coordinator is a modular, flight-ready software system for autonomous lunar rover navigation and mobility management. It builds on ProtoInnovations' decade of SBIR-funded slip estimation and traction control research and targets commercial adoption by multiple rover programs — not just VIPER.
Significance: This is ProtoInnovations' largest single award and transitions them from component R&D (wheel testing, traction algorithms) to a systems-level software product for the lunar mobility market.

Outcome Assessment¶
| Dimension | Finding |
|---|---|
| TRL advance | 6→8 — strong, among best in FO portfolio |
| VIPER relevance | Wheel testing confirmed (25 miles simulant) + EMBED flight software in cFS |
| NASA dependency | ~$24.7M+ over 14 years — de facto institutional partner |
| Active status | Two new SBIRs + Phase III active through 2027; $6.2M Tipping Point |
| Downstream | VIPER (revived, late 2027) + Mobility Coordinator for multi-rover commercial market |
FO project 158499 is not the origin of this relationship — it is one data point in a 14-year program. The TRL 6→8 result means the parabolic gravity data confirmed what lab simulations predicted: the wheel-soil interaction models are robust enough for mission use. The $6.2M Tipping Point (Jul 2023) transitions ProtoInnovations from component R&D to systems-level software, making them the only commercial company with both wheel terramechanics data AND flight-ready mobility control software for lunar rovers.
Open Threads¶
- ~~Did VIPER's actual wheel certification process use Protoinnovations data formally, or informally?~~ → Resolved Session 71: ProtoInnovations' EMBED app is integrated into VIPER's Core Flight System — this is formal flight software, not just test data. They are a flight software provider.
- ~~What is the status of the July 2025 SBIR Phase IIs — what specific technologies do they cover?~~ → Partially resolved Session 71: One is for set partitioning/LRU diagnostics (80NSSC25C0090). The other (80NSSC25C0021) description not detailed in USASpending. New Phase III (K-REX2 ROS2) started Sep 2025.
- Is Apostolopoulos still personally involved or has the company grown beyond his direct involvement?
- What is the status of the $6.2M Mobility Coordinator Tipping Point? Has it produced deliverables?
- Has ProtoInnovations been approached by any non-NASA rover programs (commercial lunar landers, DoD)?
