Agibot vs Optimus…
The firm is reported to have produced at least 962 humanoid robots so far. Global Times/Agibot Topics: Applied Physics, Artificial Intelligence, Electrical Engineering, Mechanical Engineering, Robotics The company has established a “data collection factory” to gather real-world data through activities like folding clothes and doing laundry. A Chinese robotics firm has started mass-producing humanoid robotsContinue reading “Agibot vs Optimus…”
Fast Charger…
Significant Li plating capacity from Si anode. a, Li discharge profile in a battery of Li/graphite–Li5.5PS4.5Cl1.5 (LPSCl1.5)–LGPS–LPSCl1.5–SiG at current density 0.2 mA cm–2 at room temperature. Note that SiG was made by mixing Si and graphite in one composite layer. Inset shows the schematic illustration of stages 1–3 based on SEM and EDS mapping, which illustrate the unique Li–SiContinue reading “Fast Charger…”

Credit: VTT Technical Research Centre of Finland Topics: Biology, Biotechnology, Chemistry, Materials Science, Mechanical Engineering A research group from VTT Technical Research Center of Finland has unlocked the secret behind the extraordinary mechanical properties and ultra-light weight of certain fungi. The complex architectural design of mushrooms could be mimicked and used to create new materialsContinue reading “Like Mushrooms for Plastics…”
LCE…
Topics: Materials Science, Mechanical Engineering, Nanotechnology, Robotics A new artificial fiber spun from a polymer called liquid crystal elastomer (LCE) using high-voltage electricity replicates the strength, responsiveness, and power density of human muscle fibers, scientists report. When powered by heat or near-infrared light, the fibers pulled upward and downward or oscillated back and forth. “OurContinue reading “LCE…”
Quadrupedal Robots…
Topics: Autonomous Vehicles, Mechanical Engineering, Research, Robotics Abstract Legged locomotion can extend the operational domain of robots to some of the most challenging environments on Earth. However, conventional controllers for legged locomotion are based on elaborate state machines that explicitly trigger the execution of motion primitives and reflexes. These designs have increased in complexity butContinue reading “Quadrupedal Robots…”
