In this project, you can learn how robotic technology can improve the lives of people with disabilities to help them pick everyday objects. In the laboratory, Lego Mindstorms NXT kits are used to create an artificial arm or hand that can lift small objects, such as a coffee cup.
In the process, you can discover and explore the following concepts and ideas: Hooke’s Law, hysteresis, Newton’s Second Law, accuracy and precision, rapid prototyping, and the relationship between the voltage applied to a motor and its speed.
