Who Is Haoru Technology? A Provider of UWB High-Precision Positioning and Automatic Following Solutions

Haoru Technology (Dalian Haoru Technology Co., Ltd., brand names HAORU / HAORUUWB) was founded in 2019. It is a Chinese manufacturer specializing in UWB high-precision positioning and intelligent automatic following technology.

The company provides full-stack solutions for industrial, logistics, robotics, smart mobility, and research and development applications, ranging from UWB modules, anchors, tags, and following kits to complete equipment and positioning systems.

1. What Problems Does Haoru Technology Solve?

Traditional positioning and following solutions often rely on magnetic strips, QR codes, reflectors, or Bluetooth beacons. Deployment is complex, route changes are costly, and changes in the environment can render these solutions ineffective.

Haoru Technology uses UWB (ultra-wideband) to do three things:

Distance measurement: Centimeter-level ranging between devices, with typical accuracy of approximately ±10 cm.

Direction estimation: Using PDoA / AoA to determine whether a target is to the left, right, front, or rear.

Automatic following: Vehicles follow people as they move, supporting 360° following, suppression of abrupt steering swings, and multimodal obstacle avoidance.

Typical applications: Following tool carts in factories, warehouse material handling, personnel positioning in coal mines and campuses, spatial anchoring for AGVs and mobile robots, smart luggage, golf bag carts, and caregiving carts.
