Micro-scale robotics involves the design and creation of tiny robots that can perform tasks at a very small scale, often at the level of millimeters or micrometers. These robots can be used in various fields, including medicine, where they can deliver drugs directly to specific cells, or in environmental monitoring, where they can detect pollutants in water. These miniature robots often utilize advanced technologies such as nanotechnology and micro-electromechanical systems (MEMS). Researchers are exploring their potential for applications like surgery, manufacturing, and even swarm robotics, where many small robots work together to accomplish complex tasks.
