Every manufacturing and distribution facility moves material constantly. Parts travel from storage to production. Finished goods move to staging. Cases get picked, sorted, stacked, and transferred. Most of this movement is repetitive, physically demanding, and relentless. Manual handling is also one of the most persistent sources of workplace injury, labor cost, and throughput variability in industrial operations. Workers fatigue. They call out sick. They turn over at high ra

Manual bin picking is one of the most persistent bottlenecks in manufacturing and logistics. A worker reaches into a bin, locates a part, orients it correctly, and presents it to the next process. They do this hundreds of times per shift. The task is repetitive, physically tiring, and difficult to staff consistently at the pace modern production demands. Automated bin picking replaces that manual step with a robot arm and a 3D vision system that locates parts wherever they la

When manufacturers evaluate robot arms and 3D vision cameras, two specifications appear on nearly every datasheet: accuracy and repeatability. They sound similar. They are often used interchangeably in casual conversation. In engineering terms, they measure entirely different things, and confusing them leads to real consequences when building an automation cell. A robot arm or camera can be highly repeatable but inaccurate. It can be accurate but not particularly repeatable.

"3D vision" is used as if it describes a single thing. It does not. There are at least four distinct technologies that produce 3D spatial data, each using different physics, different hardware, and suited to different industrial applications. Choosing between them without understanding those differences leads to cells that underperform or fail entirely on the parts they were supposed to handle. This post explains the four core 3D vision technologies used in industrial robotic

A 3D camera is hardware. It captures a point cloud. That is the beginning of the process, not the end of it. The point cloud is raw spatial data, a dense collection of coordinates describing the surfaces in front of the camera. It contains everything the robot needs to know about the scene. But the robot cannot act on a point cloud directly. It needs a specific pick coordinate, in its own coordinate frame, with a grasp orientation and a collision-free approach path. Translati
