Lase launches positioning system for AGVs

Laser-systems supplier Lase has launched an automatic vehicle positioning application, which can handle the positioning of automated guided vehicles (AGVs) in up to three lanes sequentially.

The LaseAVP (Automatic Positioning Vehicle) measurement system is primarily designed for ship-to-shore (STS) crane operations.

A 3D laser scanner from the LASE 3000D-C2-11x Series is mounted at the portal girder centrally above the lanes and shall detect an AGV in a specific lane, a company statement noted.

Consequently it receives the position information by the crane PLC in order to calculate the distance to the crane centre.

For this task the application has to determine the centre position as well as the skew of a free slot on an AGV and of the container for deposit tasks and pick up operations respectively.

A statement from the company explained that in a “semi-automatic environment, an AGV receives a position where it has to drive to carry or fetch a container. This position is very rough and quite inaccurate beneath the respective crane, but firstly the AGV drives to this demanded position.”

“After arriving, the crane PLC triggers the Lase system for a calculation of the position and the skew of a free slot or container on the AGV. The 3D laser scanner performs a 3D scan over the respective lane. The collected data is sent back to the PLC, which can align the crane and the spreader to the AGV position correctly now.”

The application is able to position AGVs for all common container types including 20 ft, 40 ft and 45 ft and is also applicable for single or double spreader operations.

Lase already has positioning systems for truck and straddle carriers, with the new product completing the portfolio for positioning tasks under STS cranes.
