Hyperspectral imaging for autonomous inspection of road pavement defects
A report on experiments with a hyperspectral camera to identify cracks due to exposure of the interior material of road pavement, which have different chemical composition to surface materials. Presented at ISARC 2019, Canada.
Design of a modular continuum robot segment for use in a general purpose manipulator
This paper presents the development of a tendon-driven continuum robot segment with a modular design, simple construction and significant lifting capabilities. ICRA 2019, Montreal.
Mathematics and cities: A long-standing relationship fit for the future?
A book chapter by Chris Rogers (pages 517-522) in “The Mathematics of Urban Morphology” Luca D’Acci (Ed.) 2019, published by Birkhäuser, on the mathematical challenges for sustainable and resilient infrastructure and urban systems.
Terahertz dielectric property characterization of photopolymers for additive manufacturing
Resin-based photocurable polymer materials for additive manufacturing were characterized for their comprehensive dielectric properties. For all photopolymer samples tested, the dielectric constants and loss tangents lay in a range useful for many applications.
Higher-order mode substrate integrated waveguide cavity excitation for microstrip patch antenna arrays at 30-GHz
A novel approach to the design and fabrication of low-cost and high-gain aperture-coupled microstrip patch antenna (AC-MPA) arrays for e.g. simultaneous wireless information and power transfer and Internet-of-Things connectivity.
220-320 GHz hemispherical lens antennas using digital light processed photopolymers
This paper presents a 220-320-GHz hemispherical lens antenna fabricated using photopolymer-based additive manufacture and directly fed by the standard WR-3 rectangular waveguide without any additional waveguide extension.
Human-UAV teaming in dynamic and uncertain environments
This demonstrator shows how an algorithm developed for human-agent coordination can be used to coordinate human actors on the ground and unmanned aerial vehicles in a rescue mission. AAMAS 2018, Stockholm.
Localisation of a mobile robot for bridge bearing inspection
Bridge bearings are a critical component of a bridge and require regular visual inspection to ensure the safe operation of the bridge throughout its life. However, the bearings are often located in spaces that are… Read More
