The promise is printed on their website in the clean, declarative typeface of a new hardware company: “building the first powered prosthetic knee lighter than the limb it replaces.” It’s a claim that feels less like a product spec and more like a physical correction. For decades, the trade-off has been a simple, brutal equation: more power equals more weight. Stride Robotics, a Pittsburgh-based startup founded in 2023, is betting that a new kind of actuator can break that equation. Its wedge is a proprietary artificial muscle, a technology designed to deliver high power in a package so light it could, in theory, disappear into the user’s gait [Stride Robotics, 2024].
The Wedge of Weightlessness
Stride’s entire proposition hinges on the performance of its core technology. While many powered prosthetic knees on the market rely on conventional electric motors and gearboxes, Stride is developing what it calls “lightweight, high-power artificial muscle technology” [Stride Robotics, 2024]. This is a direct continuation of co-founder and CEO Revanth Damerla’s prior work. At the University of Michigan, Damerla was co-founder and CEO of Grasp Robotics, a startup focused on developing artificial muscles for robotic hands. That research aimed to mimic human strength and dexterity, reportedly increasing actuator strength fourfold while maintaining speed, size, and weight [DBusiness Magazine, 2026]. An early review of the emerging powered prosthetics space singled out Stride’s work, noting the aim for a knee that is “lighter, quieter, more affordable, and more functional than many currently available powered options” [Be-YOU-tiful Adaptive Warrior, 2026].
The Founder’s Through-Line
The technical lineage from Grasp Robotics to Stride Robotics provides a rare thread of validation in a pre-revenue, early-stage hardware company. Damerla’s background is in the dense, material science of making machines move like biology. His published research focuses on “actuators and transmissions that match human muscle performance” for prosthetic and robotic hands [LinkedIn, 2026]. The other named founders, Sendhil Kumar and Vijay Rajan Nadadur, appear alongside Damerla in corporate records [Tracxn, 2024].

The Unproven Path to the Body
The ambition is profound, but the path is littered with the wreckage of hardware startups that couldn’t bridge the gap from lab prototype to reliable, certified, manufacturable product. Stride Robotics operates in a regulatory and commercial environment with exceptionally high barriers.
- The Certification Gauntlet. A medical device must pass rigorous FDA clearance. This process is costly, time-consuming, and requires clinical validation.
- The Manufacturing Leap. Scaling production consistently and affordably is a separate discipline from pioneering a lab breakthrough.
- The Established Incumbents. The market for advanced prosthetics includes large, entrenched players like Össur and Ottobock with decades of clinical data and reimbursement relationships.
Public records show no announced funding rounds, lead investors, or pilot customers, placing Stride firmly in the stealth R&D phase [PitchBook, 2024].
The Question Beneath the Spec
The deeper story here isn’t about actuators or grams. It’s about a quiet shift in the philosophy of assistive technology. Stride’s implicit bet is on restoration, not just of movement, but of a physical sensation of lightness. The cultural question the product is trying to answer is whether assistive tech can aspire to invisibility. Can it become so intuitive, so lightweight, so biomimetic that it stops being a tool the body carries and starts being a part the body accepts?
