According to an example aspect of the present invention, there is provided a cleaning system comprising a first guiding configured to be coupled to an object, a second guiding configured to be coupled to the object such that the second guiding is arranged at a distance from the first guiding, a first part movably coupled to the first guiding, a second part movably coupled to the second guiding, wherein the first part is movable relative to the second part, and wherein the system further comprises a drive system configured to simultaneously move the first part and the second part along the first guiding and the second guiding.

A mobile robot having a main chassis supporting a headpiece for cleaning, stripping, reconditioning or refurbishing a coating on a metal work piece. A remote controlled power module allows for locomotion of the chassis which is held to the work piece by magnets spaced apart from the work piece by a predetermined space. The chassis provides operational control of a headpiece capable of unique positioning that is possible in view of the separated chassis and headpiece combination.

The autonomous hull biofouling cleaning system includes a floating platform mounted on pontoons and having thrusters to move the platform close to a hull needing cleaning. The floating platform includes both axial and transverse sliding ballast to prevent the platform from overturning from the collection of debris. Mounted on the platform is a solar power apparatus for providing power to the various modules, a motorized hose reel, concentric hoses mounted on the reel, an ozone pumping apparatus, a vacuum debris collection apparatus, and modules for sanitizing the debris to discharge sanitized water. A submersible remotely operating cleaning system (SROCS) is attached to the hose and includes thrusters to move adjacent to the hull, electromagnetic coils to attach to the hull, and rubbing discs to remove the biofouling, the hose first pumping ozone on the biofouling and the vacuum debris hose removing the biofouling to the floating platform for processing.

The present invention was designed as a technological package capable of implementing the removal of up to 30 cm of biofouling, normally originating from sun coral, on support vessels of ships and oil platforms, without the need for help from divers. The integration of the solution consists of a robotic platform containing a robot for flat areas and a robot for recessed areas, which sends the waste originating from the removal, capturing and crushing to a modular waste-treatment system (MSET). The operations center enables the functioning of all of the integrated systems, being housed in a support vessel, which also has a system for automatically launching and recovering the robot, the control of the robotic platform containing a software architecture capable of allowing the operator to view, plan and record the missions.
