Underwater & Marine Systems
Systems designed for marine and underwater environments face special challenges for real-world adoption. We study how the fluid dynamics of operating underwater changes dexterous manipulation, and test novel robotic mechanisms in the field.
Current researchers (August 2023): All graduate students have graduated.

Fish employ whole body movement for manipulation. In our first look at this, we studied how a tail-driven head flick enables tearing of soft materials off of mixed surfaces.

Coral reefs are severely threatened, with an estimated loss of 50% of corals globally over the past three decades. Current methods of evaluating reef health are insufficient in measuring key species-level changes for scientists to interpret. Studies are in part limited by a lack of technology suitable for collecting large numbers of tissue samples quickly, especially at larger depths. The goal is to enable an affordable remotely operated vehicle (ROV) to effectively collect coral tissue samples for large-scale genetic studies.
