The most expensive tool on a vertical construction site is often the lift itself, a rented piece of equipment that hoists workers to install brackets, fasten panels, and mark layouts. For Gary Chen and Conley Oster, the co-founders of Raise Robotics, that lift is also the perfect platform for a robot. Their flagship product, the Autonomous Mobile Fabricator (AMF), is a work cell that can operate on the ground or mount directly onto a standard Genie scissor or boom lift, turning it into a semi-autonomous machine for high-precision tasks [Raise Robotics, retrieved 2026]. The bet is that by integrating into existing equipment and workflows, they can automate the most tedious and dangerous jobs in vertical construction without requiring contractors to reimagine their entire process.
The mobile manipulator wedge
Raise Robotics is not trying to build a factory on the jobsite. Instead, it is focusing on a specific wedge: high-precision layout, drilling, and fastening for vertical assemblies like curtain walls, glazing, and mass timber. These tasks are labor-intensive, require tolerances as tight as 1/16 of an inch, and expose workers to significant fall hazards [Perplexity Sonar Pro Brief, retrieved 2026]. The AMF platform, equipped with one or two Universal Robots UR20 arms, uses a combination of a total station for global positioning and onboard sensors for continuous verification to achieve that required accuracy [datadrivenaec.com, retrieved 2026]. Crucially, it is designed to work from standard 2D floor plans, avoiding a common adoption barrier in construction tech: the need for complex 3D Building Information Modeling (BIM) files.
A founder split between simulation and steel
The technical and operational split is reflected in the founding team. CEO Gary Chen came from the world of autonomous vehicles, with stints as a software engineer at Waymo and research at UC Berkeley's DeepDrive center focused on simulation-to-real-world model transfer [The Org, retrieved 2026]. COO Conley Oster brought the domain expertise, with a background in structural engineering and project management for large crane and rigging companies [RoboBusiness, retrieved 2026]. This combination of high-fidelity robotics experience and hands-on construction knowledge appears to have resonated with investors, landing the pair on the Forbes 30 Under 30 list for Manufacturing & Industry in 2026 [Forbes, Dec 2025].
Funding a rugged hardware play
Building rugged, site-ready robotics is capital intensive. Raise Robotics has raised a series of seed rounds to fund development, with total disclosed funding estimated at just over $10 million [PitchBook, retrieved 2026]. The investor syndicate includes MaC Venture Capital and Cybernetix Ventures, a firm specializing in robotics and automation [LinkedIn, retrieved 2026]. The company's funding trajectory shows consistent capital infusions to support hardware development.

The competitive field for construction robots
Raise Robotics enters a growing but fragmented field of companies applying automation to construction. Its approach differs from competitors focusing on single tasks or different parts of the workflow.
| Company | Primary Focus | Key Differentiation |
|---|---|---|
| Raise Robotics | High-precision on-site fastening & layout | Mobile manipulator platform that mounts on existing lifts; works from 2D plans. |
| Dusty Robotics | Floor layout printing | Autonomous mobile robot for printing BIM layouts directly on slab. |
| LightYX | Augmented reality layout | AR glasses and software for projecting layout plans onto surfaces for manual crews. |
| Mechasys | Robotic welding & fabrication | Focus on automated welding and steel fabrication, often in controlled environments. |
Raise Robotics's "one robot, multiple trades" pitch aims for a broader utility on the jobsite than a single-purpose machine, but that generality comes with engineering complexity.
The technical breakdown and scale risks
The core technical challenge for Raise Robotics is maintaining sub-2mm accuracy in a chaotic, dynamic environment. The system's reported 1/16-inch precision relies on a closed-loop feedback system. An external total station provides a global reference frame, while onboard vision, depth cameras, and force/torque sensors allow the robot to scan surfaces, verify its position, and adjust for real-world imperfections like uneven concrete or warped steel [datadrivenaec.com, retrieved 2026]. This sensor fusion is what enables autonomous fastener installation into pre-existing anchor channels.
The platform's environmental rating, operating in temperatures from -20°F to 120°F and in dust and rain, is a non-negotiable spec for jobsite viability [Raise Robotics, retrieved 2026]. The real test, however, will be mean time between failures (MTBF) across hundreds of units. Robotic arms in controlled factories are one thing; the same arms subjected to daily vibration on a scissor lift, construction debris, and incidental impacts are another. The most credible risk for Raise Robotics is not the core technology, but operational reliability at scale. A single robot failing on a critical path task could delay an entire crew, eroding the value proposition faster than any competitor.
To mitigate this, the company is pursuing a dual-path adoption strategy. It is targeting contractors directly while also conducting training sessions with trade unions, like a recent session with IUPAT Glazier instructors, to build familiarity and address workforce concerns [usglassmag.com, retrieved 2026]. The next twelve months will be about moving from controlled pilot projects to broader deployment with general contractors. Success will be measured not by the sophistication of the robot, but by its disappearance into the daily grind of raising a building,a reliable tool on a lift, doing the work no one wants to do.
