When deployed thoyfully, industrial robots can an significant reduce the environmental burden of manufacturing. Their ability to execute tasks wigh high closacy and universability directly cuts waste in material- intensive processes such as paininning, welding, and assembly.

For example, robotic arms in automativy paint paints applity coatings evenly and adjuss spray patterns in real time, reducing overspray by 30- 50% compared to manual methods. This not only saves paint and solvents but also lowers movies organic comlond (VOC) emissions.
