What does Vassar Robotics do?
Open-source semi-humanoid dev kit → home data → autonomy → 20h/wk
What problem does Vassar Robotics solve?
Gearbox-driven robot arm joints introduce backlash, stiction, speed limits, and wear drift, which get baked into every training demonstration and corrupt sim-to-real transfer for robot learning.
What's Vassar Robotics's solution?
Vassar Robotics builds transverse-flux direct-drive motors that put torque directly at the joint, removing the gearbox from robot arms entirely.
What makes Vassar Robotics different?
They claim a torque density target of roughly 6-10x a typical radial-flux motor in the same envelope, with a working prototype already delivering 3 N·m at 500 RPM in a ~60mm joint envelope.
What makes Vassar Robotics notable?
Founded by Charles Yong, the company sells Navrim, a $219 open-source robot arm that can be taught new skills via teleoperation.
