Pick and Place with Machine Vision Devices – The Advantages
Flexible Camera Mounting Options
No two applications are the same! Machine vision hardware can be mounted statically above the gripping area or directly on the robot arm depending on the application. Static mounting of the cameras is particularly suitable for space-critical applications or small robot arms with limited installation space, while the positioning of the camera on the robot arm increases the flexibility of the application.

Direct Communication between Camera and Robot
The 2D camera communicates directly with robots from the manufacturers UR, KUKA, and ABB via the Robotic Vision interface – there is no need to develop a separate interface or connect any separate hardware. Sample programs or an URCap for UR can be downloaded for each robot type. This makes it very easy and quick to set up the Robot Vision application – regardless of whether you are using a B60 smart camera or a machine vision controller with machine vision camera. The documented TCP/IP communication allows for connection with other manufacturers.

Seamless Integration into the uniVision Ecosystem
The wenglor uniVision 3 toolbox offers various modules for object detection, such as the modules for localization and pattern matching. Both modules enable different object types to be taught in, whereby several – even different – objects can be found in both modules and sorted, for example, by position. Variable offsets in x and y can also be implemented, which increases the flexibility of the pick-and-place application enormously: Depending on the application, it is thus possible to specify the exact point at which the robot should grab the object – at the tip, in the middle or rather at the rear. The results, such as the gripping position or the contour of the detected object, can be displayed individually and flexibly in the web-based visualization.

Reduced Cycle Times Thanks to Multi-Object Recording
In wenglor uniVision 3 software, several – even different – objects can be detected with a single image capture and their coordinates can be passed on to the robot control system. This means that the robot can grip the objects directly one after the other without having to move to the detection position for camera capture again before each grip. This reduces cycle time and greatly increases the efficiency of the pick-and-place application.

Precise Calibration with Accurate Calibration Targets
The 2D camera and robot must initially be calibrated once. Highly accurate calibration targets are available in various sizes and materials (glass for transmitted light applications, carbon fiber for incident light applications). The successful calibration process can be checked directly via a verification step.
