Digital Twins That Cut kWh, Not Just Cycle Time
Part I showed the same robot burning 20%+ extra energy depending only on placement and path. Part II asks why the digital twin, built precisely to test placements and paths before they’re built, so rarely gets pointed at energy at all.
Offline tools (RobotStudio, Process Simulate) excel at collision-free, time-feasible motion; energy is usually an add-on or ignored, so plants validate a fast cell sitting on a high-torque posture and a coincident peak. The twin did its job, the specification was incomplete. Tellingly, Part I’s 23% placement study ran inside RobotStudio: the same infrastructure…
