However, the lack of modern mechanical harvesting methods renders the honeysuckle harvesting approach still manual. Increasing labour costs and a diminishing labour pool significantly increase the production cost of honeysuckles, potentially jeopardising sustainable production. Therefore, a straddle-frame honeysuckle-picking robot, which consists of a customised electric platform and gripper, was developed and field-tested. A rotatable two degrees-of-freedom gripping end-effector was designed to adapt to different honeysuckle orientations. The YOLOv8-pose algorithm was employed to detect picking points and ascertain flower orientation. This algorithm uses the keypoint located at the upper part of the honeysuckle as the picking point, thereby ensuring accurate positioning while simultaneously detecting the angle of the connecting line between the bud head and tail relative to the horizontal line and accordingly adjusting the rotation of the gripping finger. The model demonstrated robust performance in natural field environments, achieving 0.96 precision, 0.85 recall, 0.90 F<sub>1</sub>-score, and 4.97° mean absolute error. Test results at various picking points indicated that the damage rate incurred when picking the honeysuckle in the bud's middle was about 20°%, while picking at the head resulted in minimal or no damage. For the picking performance evaluation experiment, a dataset of 2°06 honeysuckles was tested, resulting in a success rate of 66.8 %, a damage rate of 9.6°%, a positioning accuracy of 68.5°%, and average time to harvest one honeysuckle of 4.9 s. The developed honeysuckle harvest robot presents a promising solution for the automated harvesting of honeysuckle.</div></div>","PeriodicalId":9173,"journal":{"name":"Biosystems Engineering","volume":"257 ","pages":"Article 104234"},"PeriodicalIF":4.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behaviour changes in broilers serve as important indicators of their health status. In previous studies, most broiler research has focused on basic behaviours such as drinking, feeding and walking. However, with the transition to cage-free housing, more natural behaviours need to be monitored for welfare assessment. To address this issue, the article proposes a multi-behaviour monitoring model for broilers that combines computer vision. To improve the model accuracy without increasing the overall parameter amount. First, the Transformer-based MobileVitV3 lightweight network structure had been introduced into the YOLOv5. Then, the Coordinate Attention (CA) attention mechanism had been incorporated into the Backbone to focus on important features. Finally, a new loss function called Focal-DIOU had been innovatively proposed. The experimental results demonstrate that our proposed MCA-YOLOv5 model achieves the highest recognition accuracy, with precision (P) and mean Average Precision (mAP) reaching 90 % and 91 % respectively. The method further improved algorithm performance and reduced computational cost compared with the state-of-the-art, such as YOLOv5s, SSD, Faster-RCNN, YOLOv3, YOLOv4, and PPYOLO. Compared with these algorithms, the P of the proposed improved model increased by 2.0 %, 15.5 %, 9.0 %, 32.5 %, 2.7 %, 2.8 %, and 7.5 %, respectively.

Case studies are presented for different farming scenarios in Germany, Ethiopia, and Rwanda, revealing that while the initial acquisition costs of ETs are higher, the proposed purpose-driven design can lead to a substantial reduction in operational costs, and favourable electricity prices from renewable sources can lead to significant long-term savings.

Modification of the pH value is a promising approach to achieve slurry sanitisation and provide a safe organic fertiliser to farmers. Furthermore, such treatment should ideally induce a decrease of NH<sub>3</sub> or GHG emissions during storage. Therefore, the aim of the present work was to assess the effect of pH modification on NH<sub>3</sub> and GHG emissions during short-term storage of pig slurry. Three treatment strategies were considered: mineral acidification (pH 5), biological acidification (bio-acidification; pH 5) and alkalinisation (9.5). By-products from the paper-industry or carbon-rich substrates were used as alternative additives to mineral acidification. Results showed that all treatment strategies reduced <em>E. coli</em> numbers. However, complete slurry sanitisation (<1000 colony forming units (CFU) g<sup>−1</sup> slurry) was evident only with mineral acidification. A reduction of >85 % NH<sub>3</sub> emissions compared to raw slurry was obtained with slurry (bio)-acidification whereas alkalinisation led to NH<sub>3</sub> volatilisation similar to raw slurry. Sugar addition stimulated methane (CH<sub>4</sub>) emissions during storage while alkalinisation led to minimal CH<sub>4</sub> emissions. The acid by-product used for slurry acidification significantly reduced carbon dioxide (CO<sub>2</sub>) emissions. Slurry alkalinisation presented the lowest total GHG emissions, even when indirect nitrous oxide emissions were considered from volatilised NH<sub>3</sub>.
