Hesai: Lidar's next big role is slow-speed precision docking

3D lidar has long been associated with autonomous vehicles, but Hesai argues its most interesting applications now involve slow-moving operations where precise final positioning matters. The article cites aircraft gate docking, trailer coupling, vessel berthing, and robot charging as examples where success depends on accurate alignment with infrastructure or another asset. These 'last meters' are often the most difficult part of a move, and small errors can become sources of inefficiency, downtime, or operational risk as facilities automate.

Aviation is a leading example. Airports recognized the challenge long ago, and modern Advanced Visual Docking Guidance Systems (A-VDGS) are designed to guide aircraft to precise stop positions at gates, helping support passenger boarding bridge alignment, ground handling, and apron safety. New generations of systems increasingly combine lidar with other sensing technologies to improve aircraft positioning, obstacle detection, and operational visibility. The business case is clear: gate capacity is limited, efficient turnaround is essential, and misalignment between airport equipment and aircraft access points can cause significant damage, operational disruption, and potential grounding.

Logistics operators perform more docking operations than any other sector, from trailer coupling to reversing into loading bays. Industry projects have demonstrated that lidar can support trailer alignment by helping vehicles determine the position and orientation of trailers during reversing maneuvers. As logistics operators pursue higher levels of automation, positioning accuracy is becoming increasingly important.

Ports face similar challenges on a larger scale, with container terminals bringing together vessels, cranes, trucks, and automated guided vehicles. Many leading ports, such as the Port of Rotterdam, are investing in automation and digital infrastructure to improve efficiency without expanding their physical footprint. Advanced perception including 3D lidar is gaining attention in container terminals, cargo handling operations, and automated port equipment.

Rail freight is moving in the same direction through Europe's Digital Automatic Coupling (DAC) programme, which aims to automate the mechanical, electrical, pneumatic, and digital connection of freight wagons. Future automated operations will depend on accurate awareness of vehicle position and surroundings. Inside warehouses, autonomous mobile robots and automated guided vehicles must repeatedly dock with charging stations and transfer points; reliable docking directly affects system uptime and productivity.

Hesai says these examples reveal a common trend: the closer an asset gets to its destination, the more important accurate environmental awareness becomes. Together, these niche-looking applications represent millions of daily operations across some of the world's largest industries, offering safer operations, higher throughput, and better asset utilization. For the lidar industry, they are a reminder that valuable applications are not always the most visible — and that the journey often starts at walking speed.
