Transcripts
every robot is incomplete without a
robotic arm
in this video we will be making a simple
robotic arm
which can be easily replicated my name
is vinayak and you are watching
electronics is live
so let's learn something new
[Music]
we are going to use this kit and four
servo motors
[Music]
first of all test all servo motors using
test code
which sets their shaft position to
neutral
for this you need to install the servo
library by going to manage libraries in
the arduino ide
link for the test code and main code is
in the description below
[Music]
so let's make the robotic arm
let's build a middle part first
[Music]
do
[Music]
wow
[Music]
[Music]
then make the base part
[Music]
building the gripper part was difficult
so let's see it in detail
[Music]
so
[Music]
do
[Music]
[Music]
sometimes gripper was not closing
properly so you might need to cut the
gear like this
[Music]
attach the middle part with the base
[Music]
here 25 mm screw is needed which was
missing in the kit
so we had to get it from the local
hardware shop
[Music]
now let's attach the shoulder and elbow
servo motors
[Music]
[Music]
[Music]
[Music]
then attach the gripper part
[Music]
[Music]
with the help of schematic let's make
the circuit
for which we are going to use arduino
nano and hc-05 bluetooth module
[Music]
[Music]
you can do the wiring like this
[Music]
for proper communication attach a
thousand micro farad capacitor
in parallel to the supply of arduino
nano
main code is like this if you do the
wiring just like the schematic then you
can upload this code as it is
compile and upload the code to arduino
nano take the help of
comments in the code
if there is any confusion then please
take the help of schematic
let's test the robotic arm now
you can use a power bank for this
link for the app which we are using here
is in the description below
don't forget to like share and subscribe
you can write your thoughts and
suggestions in the comments below
[Music]
[Music]
[Music]
[Music]
[Music]
[Music]
thank you for watching see you in the
next video
till then good bye and take care
