“…The hardening process, which entails gradual exposure of young plants to fluctuating environmental conditions, strengthens them against potential stresses ( Bag et al., 2019 ). Transplantation, on the other hand, aids in their movement to more conducive habitats optimizing root development and plant establishment ( Shao et al., 2021 ). Concurrently, acclimatization acts as a pivotal transition assisting young plants in adapting to sheltered environments, such as greenhouses, and to the vagaries of open terrains ( Bag et al., 2019 ).…”

Vegetable cultivation stands as a pivotal element in the agricultural transformation illustrating a complex interplay between technological advancements, evolving environmental perspectives, and the growing global demand for food. This comprehensive review delves into the broad spectrum of developments in modern vegetable cultivation practices. Rooted in historical traditions, our exploration commences with conventional cultivation methods and traces the progression toward contemporary practices emphasizing the critical shifts that have refined techniques and outcomes. A significant focus is placed on the evolution of seed selection and quality assessment methods underlining the growing importance of seed treatments in enhancing both germination and plant growth. Transitioning from seeds to the soil, we investigate the transformative journey from traditional soil-based cultivation to the adoption of soilless cultures and the utilization of sustainable substrates like biochar and coir. The review also examines modern environmental controls highlighting the use of advanced greenhouse technologies and artificial intelligence in optimizing plant growth conditions. We underscore the increasing sophistication in water management strategies from advanced irrigation systems to intelligent moisture sensing. Additionally, this paper discusses the intricate aspects of precision fertilization, integrated pest management, and the expanding influence of plant growth regulators in vegetable cultivation. A special segment is dedicated to technological innovations, such as the integration of drones, robots, and state-of-the-art digital monitoring systems, in the cultivation process. While acknowledging these advancements, the review also realistically addresses the challenges and economic considerations involved in adopting cutting-edge technologies. In summary, this review not only provides a comprehensive guide to the current state of vegetable cultivation but also serves as a forward-looking reference emphasizing the critical role of continuous research and the anticipation of future developments in this field.

“…For example, Xiong et al [34] developed a low-cost dual-arm system for autonomous strawberry harvesting robots based on stepper motors. To improve the adaptability of a transplanting device to different transplanting trays, Shao et al [61] developed an adaptive transplanting device for transplanting rice seedlings, which achieved a continuous transplanting action by driving the seedling conveying device with a stepper motor, to improve its transplanting efficiency. This research outcome provided a new method for transplanting rice seedlings.…”

“…In addition, the end actuator is equipped with a proximity sensor to detect units with insufficient seedlings, without needing contact. Shao et al [61] developed a multi-adaptive rice transplanting supply device to improve the adaptability of a transplanting supply device to different transplanting trays. The designed end-effector consisted of a cylindrical claw and a U-shaped auxiliary grip, which was used for picking up and dropping the seedlings of various seedling planting devices.…”

In recent years, with the rapid development of science and technology, agricultural robots have gradually begun to replace humans, to complete various agricultural operations, changing traditional agricultural production methods. Not only is the labor input reduced, but also the production efficiency can be improved, which invariably contributes to the development of smart agriculture. This paper reviews the core technologies used for agricultural robots in non-structural environments. In addition, we review the technological progress of drive systems, control strategies, end-effectors, robotic arms, environmental perception, and other related systems. This research shows that in a non-structured agricultural environment, using cameras and light detection and ranging (LiDAR), as well as ultrasonic and satellite navigation equipment, and by integrating sensing, transmission, control, and operation, different types of actuators can be innovatively designed and developed to drive the advance of agricultural robots, to meet the delicate and complex requirements of agricultural products as operational objects, such that better productivity and standardization of agriculture can be achieved. In summary, agricultural production is developing toward a data-driven, standardized, and unmanned approach, with smart agriculture supported by actuator-driven-based agricultural robots. This paper concludes with a summary of the main existing technologies and challenges in the development of actuators for applications in agricultural robots, and the outlook regarding the primary development directions of agricultural robots in the near future.

“…In order to meet the increasing demand for vegetable planting and ensure a safe and efficient supply of seedlings, vegetable seedling production has adopted an intensive plug seedling cultivation method which is characterized by a high survival rate, low labor costs, and convenient transportation. Approximately 60% of the world’s vegetable varieties currently use plug seedling technology ( Li et al, 2021 ; Shao et al, 2021 ; Han et al, 2022 ). The plug seedlings enhanced the quality of vegetable seedlings as a whole.…”

The classification of plug seedling quality plays an active role in enhancing the quality of seedlings. The EfficientNet-B7-CBAM model, an improved convolutional neural network (CNN) model, was proposed to improve classification efficiency and reduce high cost. To ensure that the EfficientNet-B7 model simultaneously learns crucial channel and spatial location information, the convolutional block attention module (CBAM) has been incorporated. To improve the model’s ability to generalize, a transfer learning strategy and Adam optimization algorithm were introduced. A system for image acquisition collected 8,109 images of pepper plug seedlings, and data augmentation techniques improved the resulting data set. The proposed EfficientNet-B7-CBAM model achieved an average accuracy of 97.99% on the test set, 7.32% higher than before the improvement. Under the same experimental conditions, the classification accuracy increased by 8.88–20.05% to classical network models such as AlexNet, VGG16, InceptionV3, ResNet50, and DenseNet121. The proposed method had high accuracy in the plug seedling quality classification task. It was well-adapted to numerous types of plug seedlings, providing a reference for developing a fast and accurate algorithm for plug seedling quality classification.
