Agtuary co-founder Angus Muffatti on using robotics and AI to transform agri-risk analytics with remote sensing and climate modeling
Jun 24, 2025 with Angus Muffatti
Key Points
- Angus Muffatti launches cheaprobotarm.com selling low-cost robotic arms with a custom kinematic solver that produces clean training data for AI robotics, generating $1,500 in revenue on day one.
- The arm's six-degrees-of-freedom solver eliminates jerky teleoperation data that degrades model training, removing the need for dual-robot data collection setups common in current AI workflows.
- Muffatti is collaborating with a Pennsylvania welding robot operator and a NASA vision engineer toward industrial-scale AI-driven welding, tapping momentum in open-source robotics hardware that Hugging Face recently flagged as a priority.
Summary
Angus Muffatti, an Australian aerospace and mechanical engineer, launched cheaprobotarm.com on June 24, 2025, selling a small robotic arm aimed at AI and robotics researchers and hobbyists. The site generated three sales within its first day, representing roughly $1,500 in revenue. The launch was assembled overnight, with the Shopify store going live the same morning as the appearance.
The product is positioned as a more capable alternative to existing open-source arms like the LeRobot platform. Key differentiators include higher-torque servos, improved structural integrity, and a six-degrees-of-freedom industrial-quality kinematic solver that Muffatti wrote himself. That solver enables smooth, high-fidelity trajectory planning comparable to what industrial robots have used for decades.
The data quality angle is the more substantive pitch. Most low-cost robot training setups rely on human teleoperation, which produces jerky, inconsistent joint data that degrades model training. Muffatti's kinematic solver generates clean, smooth motion data from a single arm, removing the need to purchase a second robot for the puppet-style data collection that is common in current AI robotics workflows. All software is published on GitHub under an open-source license.
Muffatti is collaborating with two external contributors: Julian, who operates a welding robot shop floor in Pennsylvania, and Stephen, a NASA employee working on the vision system. The larger ambition is AI-driven welding robotics at industrial scale, with current robotic foundation models cited as the enabling layer for that goal.
Muffatti visited Varda Atomics approximately 18 months ago when it was, by his account, little more than a squat rack in an empty room, and plans to travel to the US within the next two months. The open-source robotics ecosystem, which Hugging Face has also flagged as a priority area following a recent hackathon, is drawing a surge of hardware-focused entrants after years in which software dominated startup attention.
