Robot arm assembling car

Robotic arms assemble cars with millimeter precision, revolutionizing the automotive industry since the 1960s.

About this subject

Robotic arms are a key component in modern automotive assembly lines. They perform tasks such as welding, painting, and moving heavy parts with speed and accuracy. The first industrial robot, Unimate, was installed by General Motors in 1961 to handle die-casting parts. Since then, companies like Kuka, ABB, and Fanuc have dominated the market.

These robots have joints that mimic the human arm, with up to six axes of movement. Sensors and computer vision systems allow them to adapt to variations in parts. In Brazil, automakers such as Volkswagen, Ford, and GM use robotic arms in their factories in the ABC Paulista region and elsewhere.

The main advantage is consistency: a robot can repeat the same motion thousands of times without fatigue, maintaining tolerances below 0.1 millimeter. This reduces defects and workplace accidents. Additionally, automation has increased production without compromising quality.
