Robotic devices are machines designed to perform tasks automatically or with minimal human intervention. They can be programmed to carry out specific functions, such as assembling products, performing surgeries, or even exploring other planets. These devices often use sensors and artificial intelligence to navigate and make decisions based on their environment. Common examples of robotic devices include industrial robots used in manufacturing, drones for aerial photography, and robotic vacuum cleaners that clean floors autonomously. As technology advances, robotic devices are becoming more sophisticated, allowing them to assist in various fields, including healthcare, agriculture, and entertainment.
