YUCO and MARVEL micro-AUVs: configurable autonomy for science, commercial and defence.
Seaber, based in France, has developed one of the most accessible micro-AUV architectures on the market. The YUCO family is built around a common vehicle platform configured for specific mission sets (side-scan, CTD profiling, multi-parameter sampling, eDNA, passive acoustic monitoring, 3D side-scan, high-resolution camera and carrier configurations).
The MARVEL line extends the same approach into security and defence missions with high-definition sonar, magnetometer, multibeam echosounder, 3DSS and HR camera variants, paired with USBL positioning.
Dockstr distributes the Seaber range across Sweden, Norway, Denmark and Poland, supporting users in hydrography, marine biology, harbour and inland operations, search and rescue, mine countermeasures and ASW training.
