Recently, researchers from the Department of Engineering and Applied Sciences at Harvard University have developed an intelligent small robot that does not require manual operation. It only needs to recognize the surrounding environment and work collaboratively to complete the task. The construction work of large-scale projects is like ants and bees. Each robot is input with all the blueprints of the project, walking methods, transportation methods and other basic skills, so that each robot can work freely. The robot will continue to complete its own tasks based on the work of other robots, and this cycle will continue until the entire work project is completed.
