How To Make 3 in 1 Spider Robot Using Arduino NANO and IO Expansion Shield | Complete Tutorial Video

Hi Friends,

In this tutorial, we will learn how to make an Arduino 3 in 1 Spider Robot. The spider robot's legs and body parts are made from 3D printing parts. This robot can be programmed in three ways. They are Repetitive movements, Obstacle Avoiding, and Bluetooth Control.
Arduino nano board, Nano IO Expansion Shield, and twelve SG 90 servo motors are used for the spider robot. Two 18650 li-ion batteries are used to provide power. An ultrasonic sensor is used to set Obstacle Avoiding and a Bluetooth module is used to control Bluetooth. An Android app is used to control the spider robot using Bluetooth. This Spider robot can be made into three types by changing the Arduino codes and modules.

I've not added SR20 obstactle avoidance yet. Is your method a straight up, back off and rotate 90 degrees? I was thinking of doing something a little more nuanced like use gyro to make and check small amount of rotation either side, check distance values and make decision on best way to proceed.

Greetings sir, you seem to be using very small screws, is there a possibility in which the parts can be glued not screwed? If not can you please tell the name or size of the screws that you were using.

Your spider robot is incredible, I'm thinking about building mine, while I was looking for the necessary materials I was wondering if I could use MG99S servomotors instead of the SG90 ones, do you think it could affect anything?

[alexiszavos]

hi i would like to ask if it can work with any io expansion shield as i the one i am using has 47 25v vt capacitor and doesnt have the same line as yours

[WistrelChianti]

That's hilarious. I modded the exact same mobile app to control my own quadropod!

My robot can not lift himself up. I use a 9Volt lionen rechargebel batterie and did everything in the video. Should i just by the batterie in the video?

What’s the infill Of your 3D printed parts

[_NgoTuanSang]

Is there any problem if I supply 7.5V to the servo because my charging circuit might be damaged, and I'm too lazy to buy a new one

[Technoplus-]

Can you tell me all the screws used in this project with sizes

[somsakhua]

first i can not uploads blutooth code. after that i update libary adafruit_GFX, adafruit_SSD1306 and i uploads code again it uploads done. and i connect spider to phone .it not thing move.the phone can connect to spider but i cannot control the spider

[vogel-xzsg]

Can you use a 9 Volt Batery instead of the step down module?

[byrd]

Do you have an idea on how much this little robot weighs?

[Ilovebeets]

I’m going to be making one but can I pls have a way to contact you because I’m afraid I might do something wrong or if it doesn’t work

[PogingAzkal]

what happens if you dont damage the expansion board and didnt adjust the output voltage of stepdown module to 7 volts?

[Technoplus-]

What are screws you used for this with size

[birukayele-nhfy]

the bluetooth cannot connecct to the application what would i do sir

[PogingAzkal]

do you have tutorial how to adjust the converter

[dharaneeshnagu]

Sir iam going to do this project
Givee some tips sir

[canisrigelm]

Is there anyway to contact you because I am going to build it so if I get any problems I can contact you .

[untukgame-lw]

is it still work if i use 5 volt output from step down to vin and not damage the shield board?
