Underwater Dome-Port Camera Calibration: Modeling of Refraction and Offset through N-Sphere Camera Model

ICRA 2024poster

The optical effects that are observed in underwater imagery are more complex than those in-air. This is partially because we enclose most underwater cameras in a watertight enclosure, such as a hemispheric dome window. We then observe optical issues including the distortion effects of the lens, e.g.…

Droplet: Towards Autonomous Underwater Assembly of Modular Structures

RSS 2021poster

This paper presents a first low-cost autonomous robotic system for underwater assembly of mortarless structures. The long-term goal is to enable the construction of large-scale underwater structures; such as retaining walls and artificial reefs. The approach follows the principle of co-design; the 2…

Falling Into Place: Drop Assembly of Interlocking Puzzles

RSS 2021poster

This paper explores a system for assembling structures by dropping block components into place. During and after assembly; the blocks are held together by geometric interlock; so that fasteners or mortar are only needed to bind the final block to one of its neighbors. Drop assembly is a promising st…
