The field of micro-robotics has made enormous progress in recent years. Today, micro-robots are so small that they can be sent inside pipes or even the human body. This video at Robot Uprising sheds light on several miniature robots—from the size of an insect to the size of a blood cell. ‘Robobee,’ developed by the Wyss Institute at Harvard University weighs just a fraction of a gram. The robot can carry a camera and is used in search and rescue missions. Another smallest robot is Bristlebots. It weighs only five milligrams and has the ability to move through the body to attack diseases. Today, researchers are relying on nanorobots made out of biodegradable materials to detoxify biological fluids. To learn more, watch the video.
