Freya's Cat Claws

Hi. My name is Freya. I'm working on a project for Animals, Robotics and Applied Design.

I'm going to hopefully be using this Hampedia page to provide updates on my project.

My goal is to design working, retractable claws using metal worked into a shape imitative of feline anatomy.

I expect to use a combination of magnets (how do they work?) and Shape-Memory Alloy to provide retraction/extension forces.

Here is the result of my first foray into metalworking:

Pictured is Manny, the F2 mannequin, bearing an iron hook. I'm happy with how the hook came out, and am looking forward to getting to work on my first claw (I'll need to smith half a dozen in total, at least) later this week.
