Design Principles

"Virtual prototyping and simulation are essential for de-risking the implementation of complex human-machine systems."

In complex manufacturing environments, especially those with increasing product customization, the risk of human error is high. Digital twin simulations provide a risk-free platform to test assistive technologies, like collaborative robots, and optimize human-machine interaction, thereby improving both safety and efficiency.

What This Means for Your Design

You can use computer simulations to test how humans and robots might work together on an assembly line before you actually build anything. This helps find problems with how people might get hurt or how long things take.
