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-

1. Hard cardboard
2. Hot glue
3. Strong papercraft glue
4. 3X Standard Servos
5. 4X mini servos
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.

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

<p>PLEASE make a step by step for this I would LOVE to make this robot, it is so small and wonderful</p>
<p>Oh, I think we really need a step-by-step for this cute beastie!</p>
<p>I agree! This seems to be the cutest robot here in ibles and will surely inspire a lot of hobbyists! :D</p>
<p>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.</p>
<p>Making it a step-by-step, with text <em>off</em> 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.</p>
<p>Thanks Kiteman and ASCAS. I have written one here -<strong><em><a href="http://www.instructables.com/id/How-I-made-a-robot-DS-detailed-step-by-step/" rel="nofollow">http://www.instructables.com/id/How-I-made-a-robot...</a></em></strong></p><p><strong><em>Hope you'll check it. Thanks you.</em></strong></p>
<p>I mean &quot;Thank&quot; you. :P</p>
<p>One thing I forgot to show is the pin-to-pin connections, will update that soon..</p>
<p>Really nice robot man!!</p><p>I wanted to know how you made the battery overdrain protector...like how the ATTiny85 used in it?</p><p>Again...really nice robot :)</p>
