Vassar Robotics

Vassar Robotics is an early-stage robotics company founded in 2025 by Charles Yong, an MIT graduate with degrees in mechanical engineering and computer science. The company is backed by Y Combinator (X25 batch) and Andreessen Horowitz, having raised $500,000 in seed funding. Vassar Robotics is developing ultra-affordable, semi-humanoid robot arms and mobile platforms designed to be accessible to hobbyists, educators, developers, and small businesses.

The company's founding vision centers on a staged path to general-purpose home robotics: release an open-source semi-humanoid developer kit, scale manufacturing to collect real-home behavioral data, and use that data to train increasingly capable autonomous systems capable of returning 20 or more hours per week back to users through task automation.

Vassar Robotics' flagship product is Navrim, a low-cost robot arm priced starting at $199 in Founder's Edition and $219 as an unassembled kit. Navrim is built on an enhanced version of the open-source LeRobot SO-101 platform, featuring sturdier SLA-printed components and two integrated 480p cameras for visual perception. The arm is powered by AI foundation models via a Motion Control Policy server, enabling users to teach the robot new skills through physical demonstration in as little as 30 minutes without writing any code.

The Navrim design philosophy prioritizes accessibility and democratization of robotics. By combining low-cost open-source hardware with state-of-the-art AI foundation models, Vassar Robotics aims to place capable robotic manipulation in the hands of a wide audience, accelerating data collection from diverse real-world environments and building toward genuinely autonomous household robots.

Charles Yong initiated the company through the MIT Design X accelerator, where he began by automating post-processing for metal 3D printing. The company participates in the GitHub open-source community and actively develops its software stack in public repositories, reinforcing its commitment to an open development model that invites community contribution and rapid iteration.
