Crawler System Tramper
The crawler system Tramper has been developed within the HGF Alliance ROBEX to carry scientific payloads to perform in-situ measurements at the seafloor. Therefore accurate high-resolution positioning of sensors and sampling devices is essential. Its one year long missions to extreme environments in Arctic regions impose requirements of corrosion resistance, energy efficiency and simplicity onto the design that also influence the embodiment design of the electric drives. The talk will highlight the challenges and solutions for long-term deployment of different deep-sea actuators used for biogeochemical studies.
