Underwater Robot Mimics Bacteria with 12 Spinning Arms for Advanced Movement

Swift Summary:

• Researchers at Khalifa University in Abu Dhabi have developed an underwater robot named ZodiAq, inspired by bacteria propulsion mechanisms.
• ZodiAq uses 12 flexible flagella-like arms powered by motors to move precisely across sensitive environments such as coral reefs or underwater archaeological sites.
• Movement coordination is handled by a Raspberry Pi,with sensors providing feedback on depth and motion. Communication with surface computers occurs via acoustic modems, eliminating the need for tethers.
• The robot prioritizes precision over speed: it takes 15 seconds to cover two body lengths.
• Future upgrades aim to stiffen the flagella for object manipulation tasks like sample collection or handling delicate equipment.
• Initial tests demonstrated swimming capabilities up to an hour at depths of 2.5 meters with accurate navigation.

Indian Opinion Analysis:

ZodiAq represents significant progress in underwater robotics, showcasing how inspiration from natural phenomena can lead to technological breakthroughs. Its slow yet precise movement aligns well with applications that prioritize safety and environmental preservation-areas India could explore in relation to its marine biodiversity conservation efforts and ancient underwater sites. As India strengthens its initiatives around coral reef restoration and deep-sea exploration, robots like ZodiAq could offer tools that minimize ecological disruption while achieving scientific goals. Researchers may also find collaborative pathways between India’s maritime institutions and innovators like the Khalifa University team for further refinement of these technologies.
