Introduction: Student's Wolverine Claws
This instructable will not be making professional high quality wolverine claws, however it is a start. This instructable is submitted as a summative for design class and we had free choice to make what we wanted, I had gotten the inspiration to make wolverine claws from this video by colinfurze. What colinfurze has done is beautiful, however as a high school student the chances of me getting my hands near welding, hydraulics or metal as of now is somewhat limited, so using the materials I have I came up with what can be easily named, poor man's wolverine claws.
Jumper wires or regular wires
Wire stripper if you use regular wires
Computer with Arduino app
Servo motor (MG TowerPro 995)
Access to Laser cutter (Ideal) or similar devices capable of cutting MDF
Popsicle sticks or similar lightweight but capable materials
Dowel of sorts (should match diameter of hole from hole puncher)
Step 1: Step 1: Measurements
Measure your arm
Example: You have to do the same for the wrist and forearm from where to where you intend for the box to fit It’s fine if you only do the top and sides, but you have to multiply it by two to ensure it fits around your arm Then take those measurements and draw them unfolded This is an example of what it looks like in my case Make sure when the wrist length is doubled, it is kept separate from the forearm length. This allows for a good fit without having it be too loose, you can change the multiplication factor to suit you
The slash through showing the difference, in this case my wrist only being 7 cm while the forearm is 10cm
Step 2: Step 2: Circuitry
Step 3: Step 3: Assembly and Making
For laser cutting the box you can use https://www.festi.info/boxes.py/ , in this website all you have to do is enter your measurements and it will generate an svg file.
As for the actual claw mechanism, there are two parts
1.) Actual box The box is simple, it should end up looking like a box, a little wobbly due to the different size from the front and back, but should fit good.
2.) Mechanism for claws
Basically a crank link and slider, works well, obvious to assemble
3.) Guide for claws
I cut out the dimensions(40.7×19.7×42.9mm) of the motor using a laser cutter onto a piece of wood (check attached files)
Since the motor has to be reused I taped it on for now
The guide was hot glued on vertically however
4.) Claws attachment, for this bit I just hot glued the claws on
5.) For the joint that connects the slider and link, you can use anything that fits the size of the hole punch as long as it is rigid
For connecting the crank and the link, ideally you would want something that allows for rotation, acting as a linking point.
Step 4: Step 4: Tada!
Congratulations, you have reached the end of the project, hopefully your design works and hopefully you have added cooler ‘decals’ unlike me. In the end I wrapped it up in fabric to cover the electronics, however this was due to time constraints based on the fact that this was a summative for me. You can use better fabrics and decorate it better too, allowing it to look significantly cooler. Or if you do not prefer that, you can always find a way to cover up the electronics and paint over the rest of the box.
Thank you for following this tutorial and Thank you to my teachers for believing in me and helping to keep up spirits.
