A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy
Journal of Field Robotics, EarlyView.ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

Responsible Marine Wildlife Viewing [PDF]
, 2006 Marine wildlife viewing is good for Alaska's economy, and good for the participants' souls. But is it good for the animals? The answer is yes, if boaters and tide-poolers use care when near the animals.

Remote Sensing in Ecology and Conservation, EarlyView.This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
Remote Sensing in Ecology and Conservation, EarlyView.The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Automated extraction of right whale morphometric data from drone aerial photographs
Remote Sensing in Ecology and ConservationAerial photogrammetry is a popular non‐invasive tool to measure the size, body morphometrics and body condition of wild animals. While the method can generate large datasets quickly, the lack of efficient processing tools can create bottlenecks that ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Remote Sensing in Ecology and Conservation, EarlyView.Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...
