--While most micro -robots face difficulty traveling on rugged and uneven terrain, b eetles can walk smoothly on the complex substrate without slipping or getting stuck o n the surface due to their stiffness-variable tarsi and expandable hooks on the tip of tarsi. In this study, we found that beetles actively bent and expand ed their claws regularly to crawl freely on mesh surfaces. Inspired by the crawling mechanism of the beetles, we designed an 8 -cm miniature climbing robot equipping artificial claw s to open and bend in the same cyclic manner as natural beetles. The robot can climb freely with a controllable gait on the mesh surface, steep incline of the angle of 60, and even transition surface. To our best knowledge, this is the first micro -scale robot that can climb both the mesh surface and cliffy incline. Their small size, lightweight, and strong navigation capabilities allow them to be deployed in complicated environments quickly. Numerous insect -scale robots have been developed with diversiform locomotion modes, including crawling [1-3], rolling [4-6], jumping[7-9], gliding [10, 11], and flying [12-14]. The actuators are diverse from traditional motor s [15] and pneumatic [16] to shape memory alloy [17], piezoelectric ceramics [18], and dielectric elastomer [19]. However, they can only locomote on a nearly level surface, which makes them unable to overcome barriers several times larger than their body size.

Breakthroughs, discoveries, and DIY tips sent every weekday. A tiny robot fiddler crab is helping environmental scientists better understand the complexities of animal mating rituals and rivalries. And while their initial findings published August 5 in Proceedings of the Royal Society B are helping solve these ecological mysteries, the data was only obtained at considerable peril to'Wavy Dave.' Male fiddler crabs are engaged in a constant, literal arms race. The males are known for asymmetrically sized pincers, with a dramatically larger major claw compared to its smaller one. The reason for this sexual dimorphism is mainly twofold--mating and fighting. Female fiddlers generally opt for the male with the largest major claw, which the latter advertises by waving it at potential partners more quickly than his competitors.

Protecting and restoring forest ecosystems has become an important conservation issue. Although various robots have been used for field data collection to protect forest ecosystems, the complex terrain and dense canopy make the data collection less efficient. To address this challenge, an aerial platform with bio-inspired behaviour facilitated by a bio-inspired mechanism is proposed. The platform spends minimum energy during data collection by perching on tree branches. A raptor inspired vision algorithm is used to locate a tree trunk, and then a horizontal branch on which the platform can perch is identified. A tendon-driven mechanism inspired by bat claws which requires energy only for actuation, secures the platform onto the branch using the mechanism's passive compliance. Experimental results show that the mechanism can perform perching on branches ranging from 30 mm to 80 mm in diameter. The real-world tests validated the system's ability to select and adapt to target points, and it is expected to be useful in complex forest ecosystems.

The same types of consumer-grade hobby drones heard buzzing overhead at the beach may play a key role in uncovering the Earth's remaining hidden species. For the first time, researchers recently used such a drone to discover and describe a new species of carnation hanging off of towering vertical cliffs in Hawaii. The revelation was made possible thanks to rapid advancements in drone sensor technology and a new, custom-designed claw-like plant extraction device. Details of the discovery were published this week in open access journal PhytoKeys. The newly described carnation, called Schiedea waiahuluensis, was spotted hanging off cliffs in the Waiahulu region of Hawaii's Kauaʻi island.

I miss very few things about being a teenager, but I do miss all the time I had back then to play video games. I got great joy out of binge-playing into the small hours, an opportunity I almost never get now as a busy adult. Aside from covering games for work it feels as if I barely get time to play at all, which explains my affection for games that can be polished off in a couple of evenings, rather than the gigantic, absorbing role-playing games I used to crave. I have pretty much made peace with this. My days of 100-hour epics and/or live-service online games are behind me.

Lipidomics generates large data that makes manual annotation and interpretation challenging. Lipid chemical and structural diversity with structural isomers further complicates annotation. Although, several commercial and open-source software for targeted lipid identification exists, it lacks automated method generation workflows and integration with statistical and bioinformatics tools. We have developed the Comprehensive Lipidomic Automated Workflow (CLAW) platform with integrated workflow for parsing, detailed statistical analysis and lipid annotations based on custom multiple reaction monitoring (MRM) precursor and product ion pair transitions. CLAW contains several modules including identification of carbon-carbon double bond position(s) in unsaturated lipids when combined with ozone electrospray ionization (OzESI)-MRM methodology. To demonstrate the utility of the automated workflow in CLAW, large-scale lipidomics data was collected with traditional and OzESI-MRM profiling on biological and non-biological samples. Specifically, a total of 1497 transitions organized into 10 MRM-based mass spectrometry methods were used to profile lipid droplets isolated from different brain regions of 18-24 month-old Alzheimer's disease mice and age-matched wild-type controls. Additionally, triacyclglycerols (TGs) profiles with carbon-carbon double bond specificity were generated from canola oil samples using OzESI-MRM profiling. We also developed an integrated language user interface with large language models using artificially intelligent (AI) agents that permits users to interact with the CLAW platform using a chatbot terminal to perform statistical and bioinformatic analyses. We envision CLAW pipeline to be used in high-throughput lipid structural identification tasks aiding users to generate automated lipidomics workflows ranging from data acquisition to AI agent-based bioinformatic analysis.

Multimodal UAVs (Unmanned Aerial Vehicles) are rarely capable of more than two modalities, i.e., flying and walking or flying and perching. However, being able to fly, perch, and walk could further improve their usefulness by expanding their operating envelope. For instance, an aerial robot could fly a long distance, perch in a high place to survey the surroundings, then walk to avoid obstacles that could potentially inhibit flight. Birds are capable of these three tasks, and so offer a practical example of how a robot might be developed to do the same. In this paper, we present a specialized avian-inspired claw design to enable UAVs to perch passively or walk. The key innovation is the combination of a Hoberman linkage leg with Fin Ray claw that uses the weight of the UAV to wrap the claw around a perch, or hyperextend it in the opposite direction to form a curved-up shape for stable terrestrial locomotion. Because the design uses the weight of the vehicle, the underactuated design is lightweight and low power. With the inclusion of talons, the 45g claws are capable of holding a 700g UAV to an almost 20-degree angle on a perch. In scenarios where cluttered environments impede flight and long mission times are required, such a combination of flying, perching, and walking is critical.

MSI has introduced a handheld gaming device called Claw at CES 2024 in Las Vegas. And unlike its biggest rivals the Steam Deck and the ASUS ROG Ally, it's powered by Intel's processors instead of AMD's. The Claw runs on Intel's new Core Ultra chips and comes integrated with Intel's XeSS technology, which uses advanced AI upscaling algorithms to boost FPS for a smooth gaming experience. MSI says that will allow users to enjoy even resource-intensive AAA games on a handheld device. The device also uses MSI's thermal technology design called the Cooler Boost Hyperflow that redirects airflow to cool internal components so that it doesn't overheat even after extended gaming sessions. Its battery lasts for two hours under full workload conditions, same as ROG Ally's.

At first glance, this warehouse looks like many: Forklifts unload pallets from the back of dozens of tractor-trailers. Store-bound merchandise gets sorted by department and store aisle before getting stacked high like an elaborate game of Tetris. Tasks are powered by giant automated claws and rolling robots, instead of people. The driver's seats on the forklifts are empty. Welcome to the future of Walmart.
