PLADYPOS

Built by LABUST

 

The autonomous surface platform, that carries the international flag marking underwater activity, is overactuated with 4 thrusters forming the ”X” configuration. This configuration enables motion in the horizontal plane under any orientation. The platform has been developed at the University of Zagreb Faculty of Electrical Engineering and Computing, Laboratory for Underwater Systems and Technologies. The platform was primarily developed for following divers and since then it’s application was extended to execution of multiple autonomous tasks.
