This is a follow up of my previous instructables . Please comment on that page if you like my work.

Being a robot hobbyist, after seeing the Robot Contest up on instructables ,I decided to build one new bot. I named this bot D.S after the name of one of my favourite teachers at university - Debapriyo Syam.

Here is a video



This can be used as a robotics platform for beginners. 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
12. 3 Digit Voltage Readout module

So lets start.........

Step 1: Making the base..

Through this instructables you'll see how I tried to build a successful bot and faced many problems and solved them in my own way. I request you to read this 'ible completely and then decide how are you going to build it.

As I have told I wasn't sure what was I going to make. So I started with two Bo motors ,two wheels and some cardboard. You can see my initial base design. later I discarded that and made myself a new one, You can see the details in the pictures..Initially I was going to use the wheels made for 6mm center shaft DC motors as those LOOK GOOD,but somehow the red wheels felt more stable on the BO motors. So I used them.

And oh,I used a Castor Wheel at the base to balance the robot.

thanks

i could use servos for movement (those modified for continuos rotation)

Can we make this robot using a rhino board instead of arduino board... I also wanted to know the basic difference between them...
Thanx in advance...

Awesome instructable man. liked it very much :). btw are you by any chance from Bangladesh?

Dipanjan (author)  robot_freak4 months ago

Does my name suggest it? No,I am from India, Kolkata to be more specific...glad you liked it.

Great job!

Yay you made a step by step I was on your older one and was sad because it was hard to make with the mostly picture prospective, thank you for this

Dipanjan (author)  makershaker055 months ago

Just saw you post there. Cheers! It feels great to know that you liked my creation.

Yeah I liked it! Its amazing, great job!

Without even reading your instructable and just watching the video, this is one of the best interactive robots I've seen! Now I will read your instructions and hope I can build one of my own.

Also it's MDF you are using.

Dipanjan (author)  bricabracwizard5 months ago

Thanks. I would like to see some instructables on magic tricks . Personally,I am very fond of magic.

Regarding the MDF,-is that so? Honestly speaking,I didn't know about that. I used my drawing boards as they are quite hard. Also if I wet them to some proper extend, the layers come out one by one,so I thought "hard cardboard would be the proper term". Thanks for the information.

Thank you for this great 'ible, I'm really looking forward to make my own bot ^^ !

Dipanjan (author)  Feynmaniac5 months ago

That would be great! Be sure to post details when you make one.

what was your total expenditure

Dipanjan (author)  tonyok5 months ago

Arduino board - INR 850

Hitec Hs 311 X 3- INR 1500

Vigor Micro servos X 4- INR 1300

CardBoard :P- INR 20

Sonar Sensors- INR 900

Li-Po 2S - INR 1400

DC Motors and wheels- INR 500

L293D board- INR 200

----------------------------------------------------

Total- INR 6620 = almost 110.315 USD

But the thing is that I have been collecting these things in the past few years,so I didn't have to buy them all at once. I had all of them in my stock.
