These four companies—ABB, FANUC, YASKAWA, and Kawasaki—represent the pinnacle of global industrial robotics. In the industry, the first three (along with Germany's KUKA) are known as the "Big Four," while Kawasaki follows closely with dominant positions in specialized sectors like painting and semiconductors.
Here is the detailed English translation of the comparison:

In-Depth Brand Analysis
1. ABB: The "Brain" of the Industry
ABB’s core competitiveness lies in its motion control algorithms. Their robots are famous for being "precise and stable," maintaining incredible path accuracy even at high speeds.
Software Advantage: RobotStudio is widely considered the best offline programming and simulation software in the world.
Best Use Case: If your production line requires complex logic control or extreme precision (e.g., precision electronics assembly), ABB is the top choice.
2. FANUC: The "Evergreen" of Manufacturing
FANUC is the global leader by sales volume. Its defining characteristics are extreme stability and ease of use.
Hardware Advantage: It is the only company in the world that develops and produces all core components (controllers, servo motors, and software) entirely in-house.
Best Use Case: Automotive factories. FANUC’s signature "yellow arms" are the standard for spot welding, palletizing, and machine tending. They boast an incredibly high Mean Time Between Failures (MTBF).
3. YASKAWA: The "Welding Expert"
YASKAWA started as a manufacturer of servo motors, which is why their robots have unmatched motion response speeds.
Core Strength: YASKAWA holds a massive market share in Arc Welding. Their robots are not only fast but also more price-competitive than FANUC or ABB.
Best Use Case: Metal processing, welding, and high-speed material handling. If you need high-frequency, high-speed reciprocating motion, YASKAWA offers the best value.
4. Kawasaki: The "Specialist Powerhouse"
While not part of the traditional "Big Four," Kawasaki Heavy Industries has a legendary status in heavy industry and specialized environments.
Niche Expertise: Kawasaki was a pioneer in industrial robot technology. They are a first-tier player in Painting Robots and Semiconductor Cleanroom Robots.
Best Use Case: Automotive body painting (high explosion-proof requirements), heavy-duty lifting (shipbuilding, construction machinery), and highly customized production lines.
Decision Guide: Which One to Choose?
For extreme precision and a superior software ecosystem: Choose ABB.
For maximum uptime, resale value, and automotive industry standards: Choose FANUC.
For welding efficiency and high cost-performance: Choose YASKAWA.
For specialized industries (like painting) or massive payload requirements: Choose Kawasaki.
