Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion

open access: yesSmartBot, EarlyView.
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

Sub‐Nanometer Ferroelectric Tunnel Junctions With Record‐High on‐Current Density Through Synergistic Microwave Annealing and High‐Field Activation

open access: yesSmall, EarlyView.
ABSTRACT High‐density memory systems require a high on‐state current density (Jon) to ensure fast read speeds and large sensing margins in cross‐point array applications. However, achieving high Jon in atomically thin ferroelectric tunnel junctions (FTJs) remains an unmet challenge, hindered by parasitic interfacial layer (IL), depolarization fields ...

Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

open access: yesStructural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

open access: yesVeterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.
