3D Imaging Sees Growth in Multiple Dimensions Jun 21, 2021 — From time to time, we all find ourselves forced to rummage through the cluttered jumble of our home “junk drawer” to dig out a screwdriver, battery, paper clip, or other much-needed object. For humans, this is merely cause for fleeting irritation — but for robots working on a factory floor, this same problem poses a major technological challenge. David Dechow, principal vision systems architect at Integro Technologies, said many manufacturers working with automation have...
