CUSTOM BUILD 4WD BLUETOOTH RC ROBOT USING PVC

Featured
Picture of CUSTOM BUILD 4WD BLUETOOTH RC ROBOT USING PVC

Hi guys this is my second project done by pvc , you may wonder why i choose pvs to built my projects, coz i have bunch of pvc which are leftovers of my house plumping work .and i dont wanna waste them .

PROJECT DETAILS

This is a simple Bluetooth based 4 wheel drive rc robot built in pvc frame , the advantages of this frame are

  1. It is strong and stable.
  2. so easy to make.
  3. high load capability.

  4. low cost (for me its free of cost)

  5. most important thing is it can give equal amount of pressure for all 4 wheels
  6. so its 99.9% accurate (means it can go straight )


    The reason why i discovered this idea:- i live in a place where there is less availability of robotics parts ,
    the only frame which i can get from those shop is the one which built with metal sheet ,for cheep rate .but thats notstable ,some times all wheel wont touch the ground equally and unequal distribution of force ,it cause the robot to show improper movements while its turning .

tominjose (author)  hoanghungvn9811 days ago

Yeah ,you can use any motor driver shield.

tks !!! chúng ta cần càng nhiều động cơ ?? 2 hoặc 4

tominjose (author)  hoanghungvn9811 days ago

2 là đủ

tks.. you have my voted !!!

tominjose (author)  hoanghungvn9811 days ago

Thank you!!

hey !! i can use this morto ???

hello dil2abu would like to know if the frame you used, or did u even bought ready?.If you could also would like passace me the link where you bought all the accessories.and how much you spent to the total?

If you check my previous comments in this Instructables you wil know from where I bought..
You mentioned about Frame, I made the chassis for this using a plywood and fixed L- Clamps for Dc motors..
All together I spent nearly 45 $..

I made it Tj..

Hi.. I am a noob and I love to build one like this.. I have few questions..
1) Can I use the clone version of Arduino uno?
2) Bluetooth module HC-05 can be used?
3) You have connected 9v battery to the motor driver, Wat about the power supply to the Arduino?
tominjose (author)  dil2abu1 month ago

1:Yeah you can use any kinds of arduino and its clones.

2:Yes it works on both hc-05 and hc-06.

3:In real i used same 12v battery for both arduino and motor driver .

And that 9v battery is just for illustration for circuit ,i couldn't find 12v batter on that software which i have designed the circuit .

can I use a 9v battery for both Arduino and Motor Driver?
tominjose (author)  dil2abu1 month ago

yeah it will work with one 9v battery.

its difficult to vote using instructables mobile app, if possible you can visit my project from your mobile browser or from pc,and there will be vote option .

After spending lots of hours I found these are affordable for me.. You just check those links and make sure that these will work for me.. So that i can order it right now..

Fine go for it!
use this ebay coupon for additional discount "

MOBIKWIK01"

just started my work dude.. hope everything works fine when I complete :-)

Wow Awesome all the best!! and dont forget to do "I Made it!"

what battery did u used?
any suggestions for battery?
tominjose (author)  dil2abu1 month ago

i used 3, 4v 1ah batteries

http://www.ebay.in/itm/1ah-rechargeable-battery-4v...

if you have more money then i suggest to use lipo battery

http://geb.ebay.in/g/ImportHubViewItem?itemid=2010...

Thanks for ua suggestions dude.. I'll buy the cheaper one ?
tominjose (author)  dil2abu1 month ago

Go for it ,even that works great!!!

Thanks for your reply.. what should I consider when buying a DC motor for this? Any specific Voltage or Rpm?
tominjose (author)  dil2abu1 month ago

Even it works on 9v , you can buy any rpm motors (less rpm more power)

voltage doesn't matter most dc motor works on 1-12v

Jii ive asked fr ma Forward reverse func error :(

tominjose (author)  sharkupsantosh1 month ago

shuffle the wires on 10,9 to 6,5. and if that doesn't work inter change those wires and find the proper connection.

Thanks for your fast reply, how to vote for you with the Instructables app?

So both Arduino and Motor Driver can be powered by a single 9v battery?
ajishyama1 month ago

this is cool ,well explained thanks

Following expecting more from you.

tominjose (author)  ajishyama1 month ago

:)

Every thing works fine except fwd,bckwrd commands using two motors..!

solve ma prob soon..

Did you do your build with 2 motors or 4? The title says "4WD" and the parts list shows four motors. But your parts list only shows one LM293D, your wiring diagram only shows 2 motors, and your Arduino sketch appears to be for two motors. I definitely plan to build this, but I'm just curious as to your experience with 2 versus 4 motors.

Nice design though - very simple and straightforward. Thanks for posting it.

tominjose (author)  jcantalupo1 month ago

Thank you ,hope had voted for me!
actually i used 4 motors and all circuit designed for this project only.And i only used one motor driver (lm293d) .I had connected both left side motors together ie +ve of left front motor to +ve of left back motor ,-ve of left front motor to -ve of left back motor.like so for right sides too.(check the below image)
still having doubts ??

DC-motor-pair.jpg

Could u juzz guide me wit proper pics to connect Motor diode...

i gt no responce whn i sitch it on... :(

is thr any code burnt othr than ur gvn uno file... to activate that motor driver

tominjose (author)  sharkupsantosh1 month ago

Sorry for the late replay i haven't seen your message .

That code is tested and its 100% working ,May be you got some prob with motor driver board or with your connection .
just go threw the circuit once again, if you still having trouble, upload pics of your ckts.
