I already change the code in 7/21/2020. Please download the latest one.

serialvent() is not want to call, it automatically works when data received. Please check your bluetooth tx is connected with arduino rx and bluetooth rx is connected with arduino tx.

sorry sir currently that circuit is not with me. I send the robot to a company.

Neat idea...........

So cute and nice robot...

Please see this image to get idea of the circuit.

Sir try Remove pinMode(echoPin, INPUT); from step 847 in Distancecal and add pinMode(echoPin, INPUT);pinMode(trigPin, OUTPUT); in setup

Sir actually the problem is in the ultrasonic sensor. check step 189 if the distance straight is less than 5 it see left and right otherwise it move forward. If you remove the sensor then also the distance calculated is 0. Some times this ultrasonic sensor make problem like this check the ultrasonic sensor and its all ok.

See the front and back side of the circuit.

I set 6V for servos....and for nano directly from batteries....

Its very tasty na...........

Cute dragon.....superb art work....best wishes...

Fantastic Work....

If you have Try it sir, but regulate the volt to 6 more voltage affect the servo. When i measure the amps taken when all servos running is greater than 2A that's why i use 3A. But if you use sg90 may it take low amps.

Super sir...So now you have problem in autonomous only.......First check your ultrasonic is working properly for that in the Arduino coding line 246 you able to find two variables leftdistance and rightdistance. Remove the bluetooth because it connected to arduino tx rx. Connect the arduino to pc. but the body in some height so the robot not move. Add Serial.print after the 246 line and print the leftdistance and right distance. Compile the code and from serial monitor Type A and click send now the robot take the command autonomous. Put your hand in front of the ultrasonic sensor. Now the code move to autostep3 and calculate the left and right distance and that one is found in your serial monitor. Check which one is high as per the reading in step 247 the robot decide to move left or ri...

Thank you very much

Wow want a wonderful and hard work. Best wishes.......

Thank You very Much.........

Thank You very very Much..........

Now, I uploaded in google and give the link in step 16 please download it.

Sir please check i update the head servo space

Sorry sir i have no apple phone and i dont know how to code in ios. But MIT app inventor has new options to code in ios, may you try it..... Its very easy to program in MIT app inventor even i have no basic knowledge in android but i able to create app in android.

Yes sir i did manual correction. Today i try to change it in tinker cad......Sorry for the in conveyance. Ultrasonic holder is purchase from online its very cheap and readily available so i cant make it....

Super...it looks amazing...

Any batteries with high mAh works. I check for all the servos run at same time take almost 1.8Amps.

1) Sorry i develop step by step so i don't comment.2) Comment lines are not require u better delete it.3) Yeah it is the initial servo setup but even it comment same is done in Servomovement(), so no need to uncomment for set up use the same program once setup run its is in the inital stage.4) see step 7 ist image the image detailed the servo position.5) Thank you for your complements. For more details feel free to mail me.

Thank You very much sir...Yes sir from Sivakasi, Virudhunagar Dist, Tamilnadu. You from.

Thank you very much

Thank you very sir....ESP32 is a nice idea. But using power bank is not good idea because at first i try in some other project and found while servo working it draw more current and sudden variation in voltage, this make the arduino 5v supply to reduce power and Arduino restart at when ever servo start, because the power bank out put is only 5v its is the minimum voltage for arduino. Also most of the power banks has 18650 batteries inside with same dc to dc power regulator. If you have power bank try it and send the result.

Yeah it is the last one i start make this project in 2019 with my first version.

Sir please download it again and check, when i check its on center and correct.

Thank you very much

Very Very Sorry Now only found the legs design in the tinkercad has problem, thanks to Mr.kjellgnilsson.kn for check and inform me. Now change the design file and upload. Kindly check and download. Those who already download and printed I am very very sorry, i never notice and dont know how it change.

Sir mostly samsung smart phones are android version so you can download the apk. Install it by click it.

Thank you very much.......Sorry i wrongly entered, now i changed the sets thank you very much...

Tjhank you very much.....yeah rubber in feet is better but for turning we want slippery floor. Please check my previous version the leg movement is calculated as per walk so with out rubber also not affect walk. But want to extend the leg that reduce the tilt while two leg in air.

For this project U can use UNO also, because i dont use any advance library i use only digital pins to control servo. But for this frame uno is over size. U want to put the board over the board...

Neat and easy idea for parties...

I tasted it its amazing..............

Please find the link in Step19. Click the link to download code from google drive. Due to some time programs and exe cause problem in instructables, in recent days i posted the code in google drive and give you the link. Sorry for the inconvenience

Thank you very much...

Yeah sure...

Thank You very much...

Thank you very much...I plan to add another 4 more servos for walk side wise like MIT Cheetah....

Try it its very interesting. I have no idea about ios. But MIT App inventor now launch new page for ios developer.

Looks its very spicy and yummy........superb........

Thank You very much

Thank you very much.....Yeah in previous version also some persons suggest it....due to i want to bring all in one shield i never try that. If more sensors in the future i force to use it.

非常感谢你Thank you very much....Try it its very easy.....I have some other plan to make it more easy if you able do it. In the leg make the joints easy remove then no need to stick.

V1 is a basic version it has no ultrasonic sensor and no batteries. Even lot of arduino code is updated in V2.

Thank you very much....step2 and step3 you can able to download the tinker card file. If you want to print use it or open it in tinkercard and you able to find the dimension. It you want to do it manually please refer my previous version https://www.instructables.com/id/Baby-MIT-Cheetah-Robot/.

My cute daughter looking so beautiful........

Thank You very much.....

Thank you very much.....Pondati.....

Thank You very much sir....

Muchas gracias señor ...Thank you very much sir.... Its very easy to make it give a try....One small suggestion while design for leg foot join increase the height of the cylinder by 1 inch in the cap and in the base piece. So the robot not tilt even walk in very slow motion. For walk in slow motion increase the smooth delay in the program.

Thank You very much for the God and the Managers who selected this project to publish in the front page. Its one of my dream in Instructables. Thank you again and again to make my dream happen...........

Thank you very very much.........

Superb work and it come out excellent........

Nice work...Cute birds...

Thank You very much.....

Thank You very much....

Nicely done...kids like it very much....

Thank you very much

Thank you very much....yeah kids like it very much....

Its very very tasty...........

Feel free to text me in my whats up number 9245242287

Thank You sooooooo much....

But when you transfer data you send from microcontroller so no one able to view. For report if you want you put a login screen.

That progam i attached is very simple and easy just download and view in notepad for coding.

Yeah for security reasons........
