to support camera calibration of the 3D cameras , it includes the option for GPUbased image processing for even faster 3D data processing .
Two Ensenso 3D cameras provide the system with the essential image data
It also enables the output of a single 3D point cloud of all cameras used in multi-camera operation , which is required in this case , as well as the live composition of the 3D point clouds from multiple viewing directions .
The first camera is installed above the source box in order to consider the latter as a collision object in the path planning of the robot arm . Here the unknown parts are presented and the point cloud for searching the appropriate handle point is generated . The latter is done with the help of the Mikado ARC ( Adaptive Robot Control ) software from isys vision . It combines Ensenso ’ s 3D stereo vision camera technology with an easily configurable , adaptive robot controller . The result is a complete 3D robot vision solution for bin picking and parts handling with an autonomously operating robot , as supplied by autopick . Instead of following predefined , taught and firmly defined paths , it orients itself independently in the workspace and reacts to every situation .
The second camera is above the target box . It searches for free storage positions . In addition , the Z-height of the box content is determined in order to be able to take this into account when determining the storage position . It is crucial that the target box is occupied evenly and that the products are placed carefully . The latter is particularly important when picking fragile parts . The image acquisition is asynchronous to the movement of the robot in order to optimise the cycle time .
“ We chose the Ensenso N35 for its compact design and high point cloud quality . For the considered field of view , the N series is ideal . The configuration of the camera can be easily and precisely adjusted to the respective product portfolio , or even adapted during the process ,” explains the system manager at psb intralogistics . Handle information and picking orders are exchanged via the interface to the warehouse management system .
OUTLOOK
Online trade continues to have strong growth ahead of it . At the same time , the e-commerce sector is becoming increasingly tough . Innovative intralogistics technologies are therefore often necessary to remain competitive . At the same time , hardly any economic sector is currently struggling as much with the lack of suitable young talent as logistics . The economic benefit of picking robots is therefore so substantial that they will have a permanent place in commissioning in the medium to long term . The underlying solutions with artificial intelligence will learn to master other challenges besides gripping - independently or also collaboratively in cooperation with humans , reliably and precisely . Image processing with 3D cameras , among others , provides the decisive overview and the necessary safety .

The robot picks up unknown products from bulk material and places them in the target container - 300-500 parts / h depending on the gripping object
