An Ohio State University spinoff has raised $2 million to work toward mass production of lower-cost, more durable gear for industrial robots.

Inventor Yuanfang Zheng, who retired from OSU at the end of the year as an electrical and computer engineering professor, developed the first replacement technology in decades for speed-reducing gears. Essential to robot movements, these gears translate the rotational speed of a motor into torque (rotational power) in a slower-moving outer ring. It’s a $3 billion market for the part, the company said.
