By using fusion I designed index3 , majeure3 , ringfinger3, auriculaire3 ,wrist
Hand rest...
I take some support parts on my design(rest of the hand) from
Thingivers :Parts of the hand .STL
Then insert it as mesh in fusion
and convert it to solid part as component
look this video
convert STL to editable solid part
Then take dimensions after making drowning from solid part
Fingers ..
I did same think to have a solid body to take the dimension of 6 parts of one finger
then I change scale for other3 finger
and take 5th finger from thingivers
How I take dimension from standard design
2022-04-02 16-11-00.mkvThen I sketch them
2022-04-02 16-19-48.mkvAnd then I deduced and painted those
2022-03-31 22-12-56.mkv2022-03-31 21-48-37.mkv

Arduino uno and hand holder
After exporting already nested DXF files from Fusion 360, It is time for Laserworks.
DXFs are imported in Laserworks , setting proper speed and power for cutting and scanning.

Detect finger(index3) movement--> Input sensor is flex sensor it can sense the value of bending angle by volage divider low and send these value with mapping with servo angle to slave (Arduino uno)
Bionic finger moving --> servo rotate with the value witch received from maser (Arduino nano)
5- What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)

My instructor Ahmed Abdelnaser advise to make the other parts of hand as support to the finger instead of box

Some unsuitable dimeters it make parts of finger not fit together
but I treat it by whipped up this part by cutter and sand pepper .
