这款微型机器人能当“侦察兵”

Core Insights - The article discusses the development of a micro-bionic robot inspired by the shrew, created by a research team at the University of Electronic Science and Technology of China, which showcases high mobility and collaborative capabilities [2][5]. Group 1: Robot Design and Functionality - The electronic shrew weighs only 6 grams and measures approximately 4 cm in length and 2 cm in width, featuring two micro motors, a battery, and a circuit board, allowing for agile movement in multiple directions [2][5]. - A key feature of the robot is its long yellow tail, which mimics the shrew's tail-dragging behavior, equipped with micro magnets for quick attachment when two robots come close [3][4]. - The team addressed the challenge of the magnets not being strong enough by combining dry adhesion (magnets) with wet adhesion (glue), using a special temperature-controlled polyurethane glue that solidifies at room temperature and melts when heated [4]. Group 2: Potential Applications - The electronic shrew has a battery life of approximately 45 minutes and can carry objects weighing up to twice its body weight, but its true potential lies in its ability to work in clusters [5]. - These robots can connect in a line to navigate complex terrains, such as crossing large gaps or climbing obstacles, and can work together to perform tasks that are impossible for a single unit [5]. - Potential applications include search and rescue operations in disaster zones, inspections in confined spaces, and collaborative transport of small items in challenging environments [5][6]. Group 3: Future Developments - The research team has already developed three functional robots and is working on three more, with plans for future models that can jump, fly, and swim, inspired by the survival strategies of plants and animals in nature [5].
