Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

SURFACE CLUTTER REDUCTION FOR SFCW GROUND PENETRATING RADAR [PDF]
, 2020 Ground Penetrating Radar (GPR) utilizes electromagnetic waves to be transmitted to the ground and have a non-destructive technique. In the detection process, electromagnetic waves touch the surface clutter and then it will continue to underground to ...

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Analysis of the behaviour of ground clutter on behalf of clutter suppression with solidar [PDF]
, 1991 Interest in clutter is almost universal in radar research, because most of the radar echo signals received by radar do not originate only from the desired target, but also from surrounding objects or surfaces which tend to mask the target signal.

Mosaicking Cluttered Ground Planes Based on Stereo Vision [PDF]
, 2007 Recent stereo cameras provide reliable 3D reconstructions. These are useful for selecting ground-plane points, register them and building mosaics of cluttered ground planes. In this paper we propose a 2D Iterated Closest Point (ICP) registration method, based on the distance transform, combined with a fine-tuning-registration step using directly the ...
