What is the key technological innovation within the Quadroin and why does it advance the state of the art?
This is a difficult question to answer because the complete package has to be right: The compact size and low weight make it easy to transport and handle with just one person. At the same time, the Quadroin is packed with sensors and intelligent analyses, such as automatic object recognition in the sonar and video. Everything has to work together. The Doppler velocity sonar must not interfere with the side-view sonar, the forward-looking sonar or the acoustic communication. The sensors must be cleanly decoupled electronically, e.g. from the motors. The GPS antennas must be far enough away from the water to provide a precise position, while at the same time no long antenna must stick out during the journey or transport… there are a thousand small construction sites that have to fit together so that the system is convincing in the end.
What was the biggest obstacle in your developing process? How did you overcome it?
We’d like to say that there was this one nut to crack and then suddenly everything went by itself. But the truth is that in a complex system, one detail here creates another construction site elsewhere. For example, some of the electronics are housed in pressurised carbon housings. These have to be produced to a high quality and with corresponding dimensional accuracy so that they are stable enough and, above all, leak-proof. You can’t simply use a different material, as this would completely change the dimensions and weight of the assembly and thus also shift the centre of gravity. Intensive quality controls and the selection of the right suppliers have helped us here. But it is also clear that you can never be finished with a complex system. There are always parts that are no longer available as originally planned, their quality changes or the price becomes unrealistic. Then you have to get back to it.
How does the Quadroin enhance the interaction between humans and robots, and what measures have you taken to ensure safety and efficiency?
Once the Quadroin is on a mission in the water, interactions with humans are rather rare. Of course, the Quadroin has collision avoidance systems. A high-resolution sonar with intelligent analysis. However, the actual protection of people starts with its size. Most other vehicles with comparable performance can only be moved with heavy equipment. Especially at sea, where everything sways, this poses risks.
Which industries are impacted by the Quadroin, and what feedback have you received from industry partners?
The Quadroin is set to become a universal tool for research and environmental monitoring. We think that this vehicle will efficiently collect data to understand the state of our oceans in much greater depth than is currently the case.
If you want to measure the extent of seagrass beds or the amount of bleached coral in a reef, the Quadroin provides the data.
The Quadroin is a fast operational vehicle for searching for objects or missing persons, especially at depths where you can only search to a limited extent from the surface.
The Quadroin is ideal for regular inspections of cables, pipelines, and shipping lanes.
The Quadroin can be used in a wide range of applications, which is why there is a great deal of interest from industry, environmental organisations, and authorities.
