How I Made a Robot- D.S

This is a tribute to my teacher- D.S Sir.
Building a robot can be complex,and explaining each and every details is almost impossible. So I thought why don't I show you actually how I built the bot.

At first lets take a look at some pictures and videos-


When I was about to build the bot, honestly I had no idea what was I going to make. Initially I made a base like first picture. Oh well,my main ingredients were,
1. Hard cardboard
2. Hot glue
3. Strong papercraft glue
4. 3X Standard Servos
5. 4X mini servos
6. An Arduino board (You'll know why I am not mentioning the board name here)
7. Battery
8. 2X BO motors
9. 1X castor wheel 
10. 3X Sonar sensors
11. wheels for BO motors

Ok, I made the base with cardboard,Two BO motors,Two wheels. Then it was the time for attaching servos. I attached the Servos to Cardboard and made a frame with them. 
Now I chose Breadboard for connecting the wires together.
I bought a 2S Li-po battery but I didn't have any sort of over-drain protection circuit. So I built myself one from Attiny85. But if 8.4V(Max Li-po voltage) is fed to the servos directly,they risk of being burnt out. So I used 7805 and 7806 Voltage regulators for them. 
Each of the arm of the bot has three Servos one for shoulder, one for elbow and the other for gripper. I haven't used the gripper servos till now. But they can be easily used by manually sending pulses from the board.
initially I was going to use Arduino Mega board,but AFTER connecting everything I found that the USB cable was faulty. so I had to replace the board with an UNO equivalent.

See the pictures to understand better.

EDIT: For the step by step version of this one,kindly follow this link
 

I am uploading the code for basic obstacle avoiding here. Hope you'll like this project.

    Thank you sir. Aren't the descriptions on the pictures clear? If you need any more details on any parts of the bot,I can surely provide more images. Hope that'll be helpful.

    Making it a step-by-step, with text off the pictures, makes it a lot easier to follow, especially for people who download PDF files to read offline, or who are using the app to follow along.

    One thing I forgot to show is the pin-to-pin connections, will update that soon..

    Really nice robot man!!

    I wanted to know how you made the battery overdrain protector...like how the ATTiny85 used in it?

    Again...really nice robot :)
