Three-dimensional (3D) LiDAR is crucial for the autonomous navigation of orchard mobile robots, offering comprehensive and accurate environmental perception. However, the increased richness of information provided by 3D LiDAR also leads to a higher computational burden for point cloud data processing, posing challenges to real-time navigation. To address these issues, this paper proposes a 3D point cloud optimization method based on the octree data structure for autonomous navigation of orchard mobile robots.

This paper presents a comprehensive dataset of mid-infrared spectra for dried and roasted cocoa beans ( L.), along with their corresponding theobromine and caffeine content. Infrared data were acquired using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy, while High-Performance Liquid Chromatography (HPLC) was employed to accurately quantify theobromine and caffeine in the dried cocoa beans.

Background: Existing research has shown that the parent-adolescent relationship and its associated communication and interaction styles are important for adolescent development and outcomes. Measuring parent-adolescent communication and interaction using self-report methods has substantial research limitations. Video observational methodologies offer a novel and more objective approach to measuring parent-adolescent communication and interaction from the point of view of participants.

Department of Ichthyology and Aquatic Environment, Faculty of Agricultural Sciences, University of Thessaly, Volos, Thessaly 38446, Greece.
Background: The European hake () is a commercially valuable demersal species widely distributed in the Mediterranean Sea. Assessing the condition of fish populations in their natural habitats is challenging due to the lack of reliable reference points.
Objective: This study aimed to utilize hematological analysis as an economical method to evaluate the physiological and health status of European hake, addressing the gap in hematological data for this species.
Unlocking practical wisdom through the inner voice of robots.

As Artificial Intelligence and Robotics evolve, the ethical implications of autonomous systems are becoming increasingly paramount. This article explores the role of a robot's inner speech in enhancing human phronesis - the capacity for making ethical and contextually appropriate decisions. Phronesis is a complex human trait based on experience, personality, and values, and is crucial for decisions affecting others' well-being.
