02 | Sensor Integration Became Increasingly Important
The autonomous retrofit platform incorporated four PoE cameras, two LiDAR sensors, six radar sensors, edge AI computing infrastructure, and 5G-based remote operation support.
Adding sensors improves visibility, but it also increases system complexity. Cameras, LiDAR, and radar observe the environment differently and generate data at different rates.
At 40 km/h, a mining vehicle travels approximately 22 centimeters in 20 milliseconds. When sensor observations are captured at different times, the system may be attempting to fuse data that no longer represents the same physical position. As vehicle speed increases, even small timing offsets can introduce significant spatial misalignment across sensor data.
As additional sensors were introduced, maintaining a consistent view of the environment became increasingly dependent on coordination between sensing systems. Over time, perception reliability depended less on the performance of individual sensors and more on how effectively those sensors operated together.
