When it comes to creating motion, we usually use motors, servos, or steppers. However, there are different ways to achieve movement. [Jamie Matthews] demonstrates how Nitinol wires can be used to generate motion.

Nitinol, also known as “memory wire,” is a type of metal wire made of nickel and titanium. It can remember its original shape and return to it when the temperature changes. [Jamie] uses this property to make a simple hand powered by wires from Amazon. This method imitates the way tendons move our hands, providing a clever solution.

[Jamie] explains clearly how to get started with Nitinol and its practical uses. Nitinol has been used in unconventional ways in the past, such as being used as the base for an airless tire.
