After understanding what a 3D sensor is, let's take a look at how to install the 3D smart sensor we want to install on the robot.
First, smart 3D sensors can be mounted on the robot's frame. In a rack-mounted system, the sensor is in a fixed location separate from the robot. Sensors scan the work area to locate objects and send pose data to the robotic arm. Calibration is required to establish the relationship between the sensor frame and the robot frame (often referred to as "hand-to-eye" calibration) so that the robot can pick up the objects identified in the 3D point cloud.

3D smart sensors perform calibration, point cloud collection, part localization and robot communication. The robot executes path planning logic that accurately and efficiently moves the end effector to pick up the part.
Boxing methods are common in binning, where the scan data is a point cloud consisting of many randomly stacked parts of the same object in a box. Intelligent localization software processes the point cloud to identify the next part to pick (usually at the top of the stack) and enter the manufacturing process.
