Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

Advanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

Advanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Fully Printed Variable Orifice Flowmeter with Built‐In Temperature Compensation for Application in Mechanical Ventilation

Advanced Sensor Research, EarlyView.
Additive manufacturing, specifically fused deposition modeling, offers an innovative approach to creating 3D‐printed variable orifice flowmeters with integrated temperature compensation. Using carbon‐black TPU, the primary component (a variable orifice) and the secondary element (a diaphragm pressure sensor) are fabricated.

Muscle‐Derived Small Extracellular Vesicles Mediate Exercise‐Induced Cognitive Protection in Chronic Cerebral Hypoperfusion

Advanced Science, EarlyView.
sEVs have a critical role in orchestrating interorgan crosstalk and mediating exercise‐induced therapeutic effects. Lin et al. demonstrates that sEVs miR‐17/20a‐5p mediates the muscle‐brain crosstalk and emphasizes the central role of mTOR signaling in executing molecular programs that can protect brain health in response to exercise.
