CONCERT: A Modular Reconfigurable Robot for Construction
Journal of Field Robotics, EarlyView.ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a

Journal of Field Robotics, EarlyView.ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

An Adaptive Image-stitching Algorithm for an Underwater Monitoring System
International Journal of Advanced Robotic Systems, 2014 Against the narrow range of sonar images for underwater monitoring, an adaptive sonar image-stitching algorithm is proposed in this paper. Compared with conventional sonar image-stitching algorithms, this algorithm can be applied to stitch sonar images ...

Mini-sonar---A Miniaturized Sector Scanning Sonar [PDF]
OCEANS '80, 1980 Use of small submersibles has increased in recent years. A vehicle that is simply a swimming TV camera can be made quite small, but its utility is limited because of its limited view of its surroundings. The mini-sonar program was started at NOSC to develop a small sector scanning sonar for use on small vehicles without affecting their bulk.

Journal of Field Robotics, EarlyView.ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

Baseline characteristics and enrichment results from the SONAR trial [PDF]
, 2018 Aim: The SONAR trial uses an enrichment design based on the individual response to the selective endothelin receptor antagonist atrasentan on efficacy (the degree of the individual response in the urinary albumin‐to‐creatinine ratio [UACR]) and safety/

Virtual Elastic Tether: A New Approach for Multi‐Agent Navigation in Confined Aquatic Environments
Journal of Field Robotics, EarlyView.ABSTRACT Underwater navigation is a challenging area in the field of mobile robotics due to inherent constraints in self‐localization and communication in underwater environments. Some of these challenges can be mitigated by using collaborative multi‐agent teams.
