Robot picking productivity boosted with innovative 3D vision

The ScanningRuler’s large field of view enables accurate 3D imaging of stationary objects, boosting the productivity of high-throughput robotics applications and making it easier for robot integrators to achieve volume picking in heavy industrial applications.

By combining 3D and 2D measurements, the ScanningRuler offers novel features to support fast and accurate picking of random machined parts piled in stillages, bins and baskets without requiring movement of the camera unit or the container.

With a built-in laser light source, the imaging technology is resistant to ambient light changes and provides reliable measurements with varying surface characteristics and part colours.

A single ScanningRuler can generate a complete 3D image of the content contained within the volumetric area associated with a US or Euro pallet. It promises to benefit materials handling and logistics applications such as picking or depalletising from pallets or trays, as well as a completeness check and empty space reduction.

The ScanningRuler image can be used to direct the robot’s gripping arms to select the uppermost part in a pile at its optimum gripping position and deposit it on, for example, a conveyor line or a tray. No external light sources, encoders or additional imaging equipment is needed.

The IP65 protected ScanningRuler measures 820mm by 107mm by 128mm high. The large field of view comprises a 1000mm to 2000mm scanning range over a 1000mm by 1200mm by 700mm maximum volume.
