Why use complementary sensors?
GNSS supplies an absolute reference. Inertial sensing describes motion. Stereo vision adds motion and spatial depth information. mmWave radar contributes observations such as target range. Fusion uses constraints between sensors while accounting for their limitations.
More than co-located hardware
Fusion requires aligned timestamps, coordinate frames and extrinsic calibration, together with quality and outlier handling. It estimates position, velocity, attitude and relevant quality information from available constraints, rather than merely switching between independent outputs.
Product configurations
| Model | Main configuration | Selection focus |
|---|---|---|
| O1 | GNSS/IMU + monochrome stereo | Core fusion, cost and interfaces |
| O1 MAX | GNSS/IMU + monochrome stereo + mmWave radar | Additional sensing constraints for demanding sites |
| O2 | GNSS/IMU + color stereo | Color information and semantic applications |
HopoEngine and the complete machine
The fusion engine supplies pose and related sensing information. Vehicle control, mission planning, task payloads and safety remain part of machine integration. Thermal inspection, docking, blade interlocks and charging require coordination with those systems.
Field evaluation
Assess trajectories, status and recovery in open sky, canopy, walls and indoor-outdoor transitions, then validate missions at actual speeds and payloads. Define metrics and interfaces before comparing a single headline number.
