[前沿资讯] Subsidy to develop fully automated drone workforce 进入全文

Future Farming

Groningen University has been granted a € 600,000 subsidy to develop a fully automated workforce incorporating small drones to help greenhouse growers control photosynthesis and pests better and make more precise yield predictions. The so-called Smart Industry subsidy from the Dutch organisation for scientific research NWO, was granted to the SMART-AGENTS project led by Dr. Kerstin Bunte. NWO facilitates excellent, curiosity-driven disciplinary, interdisciplinary and multidisciplinary research. In the Smart Industry program, scientists and companies work together on projects at the intersection of big data, smart industry and the creative industry. The aim is to conduct research into developing symbiotic networks of collaborative agents (drones) as a solution for logistics and agriculture/horticulture. Challenges in autonomous solutions According to the team of the SMART-AGENTS project, agricultural, horticultural and logistical (warehouses) environments are facing challenges when it comes to autonomous solutions. The sheer scale of greenhouse production for instance, makes pest control, monitoring photosynthetic efficiency and making accurate yield predictions difficult, costly and hazardous. They say there is a continuously growing demand for ‘mobile agents’ that can perform various tasks. In particular multi-platform Cyber-Physical-Systems (CPSs), in which various agents contribute to a network that solves multiple goals simultaneously. Network of small autonomous drones For this, the researchers want to develop a fully automated system with a collaborative network of small autonomous drones. With their equipment and capabilities, these drones contribute to solving key tasks. The researchers focus on the development of biomimetic micro sensors and the integration of multiple sensors for robust navigation and control in dynamic ‘living’ environments. Also if these are dark and hazy.

[学术文献] Visual Trunk Detection Using Transfer Learning and a Deep Learning-Based Coprocessor 进入全文

IEEE ACCESS

Agricultural robotics is nowadays a complex, challenging, and exciting research topic. Some agricultural environments present harsh conditions to robotics operability. In the case of steep slope vineyards, there are several challenges: terrain irregularities, characteristics of illumination, and inaccuracy/unavailability of signals emitted by the Global Navigation Satellite System (GNSS). Under these conditions, robotics navigation becomes a challenging task. To perform these tasks safely and accurately, the extraction of reliable features or landmarks from the surrounding environment is crucial. This work intends to solve this issue, performing accurate, cheap, and fast landmark extraction in steep slope vineyard context. To do so, we used a single camera and an Edge Tensor Processing Unit (TPU) provided by Google’s USB Accelerator as a small, high-performance, and low power unit suitable for image classification, object detection, and semantic segmentation. The proposed approach performs object detection using Deep Learning (DL)-based Neural Network (NN) models on this device to detect vine trunks. To train the models, Transfer Learning (TL) is used on several pre-trained versions of MobileNet V1 and MobileNet V2. A benchmark between the two models and the different pre-trained versions is performed. The models are pre-trained in a built in-house dataset, that is publicly available containing 336 different images with approximately 1,600 annotated vine trunks. There are considered two vineyards, one using camera images with the conventional infrared filter and others with an infrablue filter. Results show that this configuration allows a fast vine trunk detection, with MobileNet V2 being the most accurate retrained detector, achieving an overall Average Precision of 52.98%;. We briefly compare the proposed approach with the state-of-the-art Tiny YOLO-V3 running on Jetson TX2, showing the outperformance of the adopted system in this work. Additionally, it is also shown that the proposed detectors are suitable for the Localization and Mapping problems.

[学术文献] Crop design for improved robotic harvesting: A case study of sweet pepper harvesting 进入全文

BIOSYSTEMS ENGINEERING

Current harvesting robots have limited performance, due to the unstructured and dynamic nature of both the target crops and their environment. Efforts to date focus on improving sensing and robotic systems. This paper presents a parallel approach, to 'design' the crop and its environment to best fit the robot, similar to robotic integration in industrial robot deployments. A systematic methodology to select and modify the crop 'design' (crop and environment) to improve robotic harvesting is presented. We define crop-dependent robotic features for successful harvesting (e.g., visibility, reachability), from which associated crop features are identified (e.g., crop density, internode length). Methods to influence the crop features are derived (e.g., cultivation practices, climate control) along with a methodological approach to evaluate the proposed designs. A case study of crop 'design' for robotic sweet pepper harvesting is presented, with statistical analyses of influential parameters. Since comparison of the multitude of existing crops and possible modifications is impossible due to complexity and time limitations, a sequential field experimental setup is planned. Experiments over three years, 10 cultivars, two climate control conditions, two cultivation techniques and two artificial illumination types were performed. Results showed how modifying the crop effects the crops characteristics influencing robotic harvesting by increased visibility and reachability. The systematic crop 'design' approach also led to robot design recommendations. The presented 'engineering' the crop 'design' framework highlights the importance of close synergy between crop and robot design achieved by strong collaboration between robotic and agronomy experts resulting in improved robotic harvesting performance.

[学术文献] Hybrid Signal-Processing Method Based on Neural Network for Prediction of NO3, K, Ca, and Mg Ions in Hydroponic Solutions Using an Array of Ion-Selective Electrodes 进入全文

SENSORS

In closed hydroponics, fast and continuous measurement of individual nutrient concentrations is necessary to improve water- and nutrient-use efficiencies and crop production. Ion-selective electrodes (ISEs) could be one of the most attractive tools for hydroponic applications. However, signal drifts over time and interferences from other ions present in hydroponic solutions make it difficult to use the ISEs in hydroponic solutions. In this study, hybrid signal processing combining a two-point normalization (TPN) method for the effective compensation of the drifts and a back propagation artificial neural network (ANN) algorithm for the interpretation of the interferences was developed. In addition, the ANN-based approach for the prediction of Mg concentration which had no feasible ISE was conducted by interpreting the signals from a sensor array consisting of electrical conductivity (EC) and ion-selective electrodes (NO3, K, and Ca). From the application test using 8 samples from real greenhouses, the hybrid method based on a combination of the TPN and ANN methods showed relatively low root mean square errors of 47.2, 13.2, and 18.9 mg.L-1 with coefficients of variation (CVs) below 10% for NO3, K, and Ca, respectively, compared to those obtained by separate use of the two methods. Furthermore, the Mg prediction results with a root mean square error (RMSE) of 14.6 mg.L-1 over the range of 10-60 mg.L-1 showed potential as an approximate diagnostic tool to measure Mg in hydroponic solutions. These results demonstrate that the hybrid method can improve the accuracy and feasibility of ISEs in hydroponic applications.
