Robotic arm

this is the firtst 3d model i've ever made

This is a model i had to make for school. It's a arm wich can be controlled trough bluetooth i couldn't upload the apk so if you'd want to make this you will have to repoduce the code from my pictures. the site i used was  https://appinventor.mit.edu/explore/ai2 .

i used an arduino mega as the main board and a HC-05 for the bluetooth connection.

for the servo's i used 2x MG90S servo's, 2x MG996R servo's and 2x TD8130 servo's

I used an old 20V laptop power supply as power with 2 XL4005 DC-DC converters

to help the servo's i also added bearings everywhere 

i printed everything with black eSun PLA+

i think that is all

probably forgot some things tho
