fluke is a diving robot used to explore the largely uncharted world of the deep sea. The burgeoning scarcity of resources on dry land is heightening interest in the unknown regions of earth. Data collected by fluke serves to deepen our understanding of the ocean as an ecosystem. The research probes are equipped with flexible, pressure-resistant carriers suitable for holding various sensors in order to prepare for the respective mission. Extremely effective and featuring reduced energy consumption, the low-complexity drive system concept is based on the movements of a fish and can be manufactured at low cost.
