Ottobock leads $10.5 million Series A for prosthetic-control startup Blue Arbor

Blue Arbor Technologies announced on October 28, 2026 that it closed a $10.5 million Series A round led by Ottobock, which the release calls its strategic partner. The Michigan company is developing the RESTORE neuromuscular interface, which connects a user's peripheral nervous system to a robotic prosthetic limb, first as an external sensing unit and later as a fully implantable unit. The funds go to feasibility studies, an FDA Investigational Device Exemption application for U.S. clinical studies of the external unit, and development of the implantable unit.

Why it matters. Ottobock is putting capital behind upper-limb control technology that is still pre-clearance, so O&P and complex-rehab providers should expect no product change in the near term.
