Autonomous inspection boat

Precise depth measurements with igus® components

Art Robotics is a Belgian tech start-up active in the fields of robotics, IoT and AI. For its customer “Port of Antwerp-Bruges”, the company was commissioned to create the system for an autonomous inspection boat called “Echodrone”. This should be able to carry out a variety of depth measurements to ensure safe passage for shipping. It is a self-driving system that can navigate to desired inspection locations. You can read about the special features and challenges of this order in this application report.

Profile

What was needed: DC motor and data cables
Requirements: An autonomous inspection boat requires components that are robust and maintenance-free. Furthermore, the products must withstand the harsh conditions in the port.
Industry: Boats
Success for the customer: Our DC motors offer a reliable solution that is particularly space-saving without a motor flange and coupling. The fully shielded chainflex® data cables can also withstand extreme conditions.

Problem

A special system was required for precise depth measurement. A sound velocity profiler (SVP) had to be positioned near the seabed. As the Echodrone is an unmanned vessel, an additional system is required to automatically bring the sensor to and from the exact depth target. The Art Robotics team was supposed to accompany the entire development process from the concept to the finished system.

The inspection boat should also be designed to withstand all climatic conditions to which it is exposed in the harbour. This includes the ability to move in adverse weather conditions. Tasks should be performed independently, including navigating the port area and collecting and transmitting information. A reliable and secure communication link is therefore in great demand.

Solution

With the help of igus® components, Art Robotics developed a tailor-made solution for the use of the Echodrone in the "Port of Antwerp-Bruges". This solution consists, a.o., of high-quality chainflex® cables and the drylin® E DC motor. The developed system enables automatic execution of depth measurements, rapid positioning of the sound velocity profiler and remote configuration via a special software application. The modular design also allows components to be quickly and easily dismantled for maintenance purposes.

The chainflex® data cables from igus® are flexible and robust and ensure a reliable energy supply to the Echodrone during operation. They protect the cables from external influences such as dirt or moisture and thereby prevent possible failures or damage. The drylin® E DC motor used has a protective housing with IP41 protection class. This makes it more resistant to external impacts and also protects against vertical dripping water. Together, these components contribute to a precise system and can withstand the demanding requirements of the port.
