PRECISION IN MOTION
Powering the future of collaborative robotics
Collaborative robots (cobots) are revolutionizing manufacturing by working safely alongside human operators. These sophisticated 6-degree-of-freedom systems require precise motor control, reliable sensing, and robust power management to deliver the accuracy and safety that modern automation demands.
From automotive assembly lines to electronics manufacturing, cobots are transforming how we approach precision tasks. The key to their success lies in advanced semiconductor solutions that enable seamless human-robot collaboration while maintaining the highest standards of performance and safety. Modern cobots must balance multiple competing requirements: they need the precision and repeatability of traditional industrial robots while incorporating the safety features and intuitive operation necessary for human collaboration. This requires sophisticated control algorithms and advanced sensing capabilities that can adapt to dynamic operating conditions while ensuring consistent, reliable performance across diverse manufacturing environments.
