Bionic pangolin robot
Recently, researchers from the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, created a microrobot that can "navigate" inside the human body. Relevant results have been published in the journal Nature Communications.
Pangolins use their interlocking keratin scales to move fluidly through complex environments, curling themselves into a ball when necessary. Inspired by this, researchers developed a micro-robot that resembles a pangolin. The robot uses a composite structure, with an inner layer of soft polymer inlaid with magnetic particles and an outer layer of hard top layer, with its "hard scales" made of aluminum. In a low-frequency magnetic field environment, researchers can control it to move and roll. When rolled up, the robot can deliver particles such as drugs to target areas in the body. In a high-frequency magnetic field environment, it can be heated to above 70°C to treat internal bleeding, blood clots, or remove tumor tissue.
In experimental tests, the robot can move without damaging soft tissue, cover the bleeding site and heat it to achieve hemostasis. Researchers believe that this robot will play an important role in difficult internal treatments and surgeries in the human body in the future.
Bionic bee robot
Not long ago, the "IEEE Transactions on Robotics" published an article stating that a research team from Washington State University in the United States designed a bionic bee robot that can fly stably in all directions.
For flying insect robots, controlling their yaw axis during flight is a huge challenge. Inspired by the way bees fly, the researchers controlled the yaw axis by independently changing the beating speed of each wing. This allows the robot to flexibly "twist" during flight. The robot has four wings made of carbon fiber and tape, each of which is controlled by a separate actuator, thus solving the problem of force and torque cancellation when the four wings flap at the same speed. Compared with ordinary flapping-wing micro-aircraft, which can only fly in one direction, this robot realizes pitch, roll, yaw and other motion modes through the coordinated cooperation of its four wings, making it more flexible.
It is said that the robot can perform search and rescue reconnaissance, environmental monitoring and other tasks in a small space, and can also be used in artificial pollination of crops and other fields.
Bionic centipede robot
Recently, researchers from Osaka University in Japan developed a bionic centipede robot, and the relevant results were published in the magazine "Soft Robots".
Inspired by the way centipedes crawl, the researchers designed this robot based on the centipede's multi-legged characteristics and ability to adjust its shape according to the environment. The robot consists of 6 parts, each part contains two legs, which are connected by flexible joints and can yaw or move in different directions. The researchers controlled the flexibility of its body axis to allow it to walk in a curved pattern. This method of movement not only provides greater stability and maneuverability, but also greatly reduces the complexity of calculations and the energy requirements required to operate the robot, and its off-road capabilities are further improved.
According to researchers, the robot can be used for search and rescue missions, and may be used in working in dangerous environments or scientific research in the future.
