Doctors, nurses, and other medical professionals can help you feel better when you are sick. Robots can too. They check up on patients, help paralyzed people move again, and even perform surgery. Informational text, fascinating facts, and full-color images tell the story of how robots are helping transform medicine. A "Words to Know" feature helps students master new vocabulary. The book includes a hands-on activity that will help students understand how robotic hands work, and it supports the NGSS K-2 Engineering Design Standards.
