Here's a closer look at the "Big Four" robotics companies: FANUC, ABB, Yaskawa, and KUKA, as well as Teradyne (TER +6.82%), the owner of Universal Robots. All these industrial stocks have publicly available robotics-segment financials. Epson, Kawasaki, and Denso are also top robotics companies with sizable brand shares, but they aren't covered here because they don't report robotics revenue separately.
FANUC
Based in Oshino, Japan, FANUC is the largest manufacturer of industrial robots and computer numerical control (CNC) systems. Its robot division generated 378.6 billion Japanese yen (about $2.4 billion) in sales in its FY2025. That accounted for 44.1% of the company's full-year revenue of 857.8 billion yen.
ABB
A Swiss company headquartered in Zurich, ABB was the world's second-largest producer of industrial robots. It agreed to sell its robotics division to SoftBank for approximately $5.4 billion in October 2025. ABB reported $2.3 billion in revenue from its robotics and discrete automation segment in 2025, 7.0% of its total revenue that year of $33.2 billion.
Yaskawa
Yaskawa is a Japanese robotics company with three business segments: motion control, robotics, and systems engineering. Its robotics segment, which includes sales of industrial robots, generated revenue of 247.0 billion yen (about $1.5 billion) in FY2025. That was 45.9% of its full-year revenue of 537.7 billion yen.
KUKA
Founded in 1898, KUKA is one of the world's oldest robotics companies. It's based in Augsburg, Germany, and is now owned by China's Midea Group. KUKA's robotics segment generated revenue of about 1.0 billion euros (about $1.2 billion) in 2025, 25.9% of its total revenue of 3.9 billion euros.
Teradyne/Universal Robots
Teradyne is an American semiconductor company based in Massachusetts, but it also became one of the leading robotics companies through a pair of acquisitions. It purchased Universal Robots in 2015 and Mobile Industrial Robots in 2018. Robotics makes up a smaller portion of Teradyne's sales. In 2025, its robotics segment generated $308.3 million in revenue, which was 9.7% of its total revenue of $3.2 billion.
