Dual-unloading mode revolutionizes rice harvesting and transportation

Dual-unloading mode revolutionizes rice harvesting and transportation

(Press-News.org)

In a recent study published in Engineering, a team of researchers led by Wenyu Zhang from South China Agricultural University has developed a groundbreaking cotransporter system that combines a tracked rice harvester and transporter for fully autonomous harvesting, unloading, and transportation operations.

The key innovation of this system lies in the proposed dual-unloading mode, which includes two distinct methods: harvester waiting for unloading (HWU) and transporter following for unloading (TFU). In the HWU system, the harvester halts and summons the transporter when its grain tank reaches a specific threshold. In contrast, the TFU system allows the transporter to follow the harvester during the straight sections of harvesting, enabling continuous unloading without the need for the harvester to stop. This dual-mode approach significantly enhances operational efficiency by minimizing downtime and optimizing the use of resources.

To orchestrate the complex collaborative operation between the harvester and transporter, the researchers designed a harvesting-unloading-transportation (HUT) strategy. Leveraging the concept of finite-state machines (FSMs), they broke down the process into eight primary stages and constructed a state-transition chain. This modular design not only simplifies the control logic but also enables easy maintenance and upgrades, ensuring the system’s adaptability to various field conditions and operational requirements.

The team conducted extensive simulations and field-harvesting experiments to validate the effectiveness of their system. The results were remarkable, with the cotransporter system achieving a harvest efficiency of 0.42 hm2∙h−1. Field tests demonstrated that the HUT collaborative operation strategy seamlessly integrated path planning, tracking control, inter-vehicle communication, and collaborative operation control, allowing the system to complete the entire process autonomously.

This research represents a significant step forward in the development of unmanned farming technology. By addressing the challenges associated with multi-vehicle collaboration and complex operational processes, the new cotransporter system and HUT strategy have the potential to transform the agricultural industry. Future work will focus on further optimizing the system’s performance, improving sensor accuracy for real-time path planning, and exploring additional applications in other crops and farming scenarios.

Researchers uncover strong light-matter interactions in quantum spin liquids

Researchers uncover strong light-matter interactions in quantum spin liquids
2024-12-12
Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, they remain in a constantly fluctuating, entangled state. This unusual behavior is governed by complex quantum rules, leading to emergent properties that resemble fundamental aspects of our universe such as the interactions of light and matter. Despite its intriguing implications, experimentally proving ...

More dense, populated neighborhoods inspire people to walk more

2024-12-12
SPOKANE, Wash. – Adding strong evidence in support of “walkable” neighborhoods, a large national study found that the built environment can indeed increase how much people walk. The study, published in the American Journal of Epidemiology, showed a strong connection between place and activity by studying about 11,000 twins, which helps control for family influences and genetic factors. The researchers found that each 1% increase in an area’s “walkability” resulted in 0.42% increase in neighborhood walking. When scaled up, that means a 55% increase in the walkability of the surrounding neighborhood ...

Innovative biomimetic superhydrophobic coating combines repair and buffering properties for superior anti-erosion

Innovative biomimetic superhydrophobic coating combines repair and buffering properties for superior anti-erosion
2024-12-12
The long-term erosion and corrosion issues during the development of offshore oil and gas fields pose significant threats to the safe and efficient operation of these facilities. Superhydrophobic coatings, known for their ability to reduce interactions between corrosive substances and substrates, have garnered considerable attention. However, their poor mechanical properties often hinder their long-term application in practical working environments. To address this challenge, a research team led by Prof. Yuekun Lai from Fuzhou University and Prof. Xuewen Cao from China University of Petroleum (East China) has developed a biomimetic dental enamel coating with ...

New analytical approach revolutionizes reliability evaluation of power systems with renewable energy
2024-12-12
In a recent study published in Engineering, a team of researchers led by Bo Hu and Changzheng Shao from Chongqing University in China has introduced a novel method for evaluating the real-time dynamic reliability of composite power systems integrated with renewable energy sources (RES). The research addresses the challenges posed by the uncertainties associated with RES, which have been a significant obstacle in ensuring the stable and reliable operation of power grids. The increasing integration of RES, such as wind and solar power, into the power grid has brought about concerns regarding power imbalance and load shedding due to their ...

The future of breast cancer screening and risk-reducing strategies is being shaped by artificial intelligence (AI), according to a review article published by Cell Press on December 12 in the journal Trends in Cancer. “We discuss recent advances in AI-assisted breast cancer risk prediction, what this means for the future of breast cancer screening and prevention, and the key research needed to progress mammographic features from research into clinical practice,” says senior study author Erik Thompson of the Queensland University of Technology in Brisbane, Australia. Breast tissue that appears white on ...

Brain tumors hijack circadian clock to grow

2024-12-12
Virtually every cell in the human body has an internal clock. These clocks take their cues from a central clock in the brain. In a normal, biological process called synchrony, the central clock coordinates daily rhythms around the body, so that every cell and tissue recognizes the same external time of day. Knowing local time helps our bodies to regulate essential processes, including when to sleep and wake, when to eat and what temperature to maintain, among many other important functions. But a deadly interloper is keeping time the same ...

Trends in school mental health and substance use education

2024-12-12
About The Study: From 2008-2020, teachers reported an increase in emotional/mental health and suicide prevention in schools, along with related teacher training. However, they reported a decrease in substance use prevention, particularly among middle schools, and no change in teacher training. Substance use during early adolescence is associated with risk for long-term addiction, and middle schools may be underused for prevention.  Corresponding Author: To contact the corresponding author, Chloe Gao, BHSc, email chloe.gao@childrens.harvard.edu.

Genes that determine tooth shape identified

2024-12-12
Genetic variants that determine the shape of your teeth – including a gene inherited from Neanderthals – have been identified by a team co-led by UCL researchers. In a new paper published in Current Biology, scientists found substantial tooth differences between ethnicities, potentially due in part to a gene inherited from Neanderthals that was only found in study participants of European origin. Co-lead author Dr Kaustubh Adhikari (UCL Genetics, Evolution & Environment and The Open University) said: “Teeth ...
