JPL Gecko Adhesive Grippers → ISS Demo + OnRobot Commercial Spinoff

Category: Commercial Spinoff (NASA Spinoff) + ISS Demo | Confidence: Confirmed
Last updated: 2026-04-07 (Session 95)

Summary

JPL's gecko-inspired adhesive gripper was tested in microgravity via FO, then deployed on the ISS on Astrobee robots, and commercialized by OnRobot (via Perception Robotics → OnRobot merger). The technology has dual applications: industrial robotics (commercial product) and orbital debris capture (active NASA research program).

Timeline:
FO parabolic flight (2014-2016, TRL5→6) → ISS Astrobee demo (April 2021) → OnRobot commercial product (shipping 2018+) → Phoenix Gecko Gripper for debris capture (active JPL program)

FO Project

91341 — Testing ON-OFF Gecko Adhesive Grippers in Microgravity

  • Period: 2014-05-20 – 2016-02-28 | TRL: 5 → 6
  • PI: Aaron J. Parness (JPL) | Co-I: Matt Heverly (JPL)
  • Technology: Gecko-inspired adhesive grippers using millions of micro-scaled fibrillar stalks that adhere via van der Waals forces — same mechanism as gecko toe pads
  • Key feature: can be turned ON and OFF and reused many times; adheres to virtually any surface
  • FO objective: Validate gripper performance in a realistic unconstrained microgravity environment (aircraft parabolic flights cannot replicate the continuous microgravity of orbit)
  • Result: TRL5→6; grippers successfully demonstrated grappling of non-cooperative objects in weightlessness
  • Outcome field: "Advanced From | 2014-05-20 | partner: Other" — built on prior JPL SBIR-funded gecko adhesive research
  • Library items: JPL linked directly to ISS experiments and Stanford news articles within the TechPort record, confirming they tracked the downstream deployment themselves

ISS Demonstration (2021)

  • Experiment: Gecko gripper integrated with Astrobee free-flying robot on ISS
  • Date: April 9 and April 15, 2021
  • Crew: Astronauts Kate Rubins (PhD '06, Stanford) and Victor Glover assisted
  • Results: Successful — achieved 3.15 N perching force; Astrobee attached to and perched on ISS wall
  • PI for ISS experiment: Marco Pavone (Stanford) + JPL team
  • JPL/Stanford collaboration: JPL developed the gripper hardware; Stanford's Autonomous Systems Lab validated the robotic control
  • Publication: Results published in IEEE Robotics & Automation Magazine (Oct 2022): "Testing Gecko-Inspired Adhesives with Astrobee Aboard the International Space Station: Readying the Technology for Space"
  • Phase: Part of a three-phase plan — Phase 1 (grip test) complete; Phases 2-3 focus on autonomous perception and broader debris capture scenarios. No Phase 2-3 updates found as of Apr 2026. A 2024 NTRS paper on Astrobee's five-year research summary (NTRS 20240005009) lists gecko materials as "completed" research — suggesting the ISS line of investigation has concluded without further on-orbit testing.

Significance: The FO parabolic flights validated the basic microgravity mechanics (TRL5→6); the ISS Astrobee demo validated long-duration performance in a real orbital environment (effectively TRL7+).

Commercial Spinoff — OnRobot

  • Inventor: Nick Wettels (JPL alumni, now R&D Director at OnRobot)
  • License: Technology licensed from Stanford University and Caltech (which manages JPL)
  • Company path:
  • Wettels founded Perception Robotics with SBIR Phase I + II contracts from JPL
  • 2018: Perception Robotics merged with OptoForce (Hungarian) and OnRobot (Danish)
  • OnRobot became the first company to offer a commercial gecko-inspired robotic gripper
  • Commercial product: OnRobot Gecko Gripper — now available in three SP models (SP1, SP3, SP5 by payload capacity). Won the IERA Award. Distributed by Marvin Robotics, Thinkbot Solutions, Southwestern PTS, Samsys, and others.
  • Shipping: First units shipped ~mid-2018; still actively sold as of 2026

Industrial applications: Moving circuit boards, solar panels, smooth fragile objects in manufacturing settings — superior to suction cups (works on porous surfaces, no air required, low force).

NASA Spinoff: Published in NASA Spinoff magazine — confirmed spinoff story.

Space Debris Application — Phoenix Gecko Gripper

JPL maintains a separate research track for the space application: - Program: "Gecko-like Adhesives for Orbital Debris Applications" (dedicated JPL research page) - Problem: Orbital debris rotates and tumbles; traditional docking mechanisms require cooperative targets; gecko adhesive requires no specific attachment point - Product: "Phoenix Gecko Gripper" — designed specifically for debris capture and satellite servicing - Status: Active JPL program (research, not yet deployed on a mission) - Limitation: The commercial gripper (industrial) and the orbital debris gripper (space) are different products; the FO project contributed to both lineages

PI Departure (Session 46 update)

Aaron Parness left JPL after 9 years and is now Director of Applied Science, Robotics & AI at Amazon Robotics. He leads the Vulcan robot program — Amazon's first robot with tactile sensing ("a sense of touch"), unveiled May 2025. Vulcan status (Session 65 update): Operational at Spokane, WA and Hamburg, Germany; has processed 500,000+ orders; team grown to 250+ employees in 3 years; can pick/stow ~75% of all item types at fulfillment center speeds. Amazon plans to expand Vulcan to more U.S. and German facilities in 2026. Parness keynoted the 2025 Robotics Summit. No ongoing gecko adhesive work at Amazon. This is a significant PI departure — the space debris application may lose momentum without its inventor's institutional push at JPL. The Astrobee ISS research using gecko materials is now listed as "completed" (NTRS 20240005009), suggesting the ISS line of investigation concluded without further on-orbit testing.

TRL and Outcome Assessment

Stage Date Event TRL
FO parabolic flight 2014-2016 Microgravity validation 5→6
ISS integration 2019 Gripper sent to station 6
ISS Astrobee demo Apr 2021 Successful orbital test 7+
Commercial product 2018+ OnRobot shipping — (commercial)
Phoenix/debris Ongoing JPL orbital debris program ~5-6

Confidence Assessment

  • FO → ISS demo: Confirmed (NASA mission page, Stanford press release, JPL news)
  • Commercial spinoff (OnRobot): Confirmed (NASA Spinoff article, company merger documentation)
  • FO causal link: Suggestive (the FO parabolic flights were one validation step; Stanford's ISS demo primarily credited to Astrobee integration work, but the underlying gripper technology was FO-validated)
  • Downstream $: OnRobot is a private company; no USASpending contracts for gecko gripper found; Perception Robotics SBIR funding not quantified here

Key Insight

This is the standard NASA Spinoff archetype — academic technology (JPL + Stanford) validated through FO, commercialized via SBIR → startup → acquisition, and simultaneously continuing on a space debris application track. The commercial product (manufacturing) is paying the bills while the space debris application matures. FO was one validation node in a longer chain that included years of SBIR funding and Stanford collaborations.

Unusual feature: The FO project directly hyperlinked to the ISS experiment and commercial product within its own TechPort record — rare evidence that the FO program tracked the downstream commercialization.
