Picture of Build a robot boat using water bottles
This will show you how to build a robot boat from cheap and easy to use materials, I think it is also a good example of reusing water bottles.

I used two water bottles, polymorph plastic, two motors and propellers, tape, a box, a battery and a motoruino (Arduino clone designed to work with motors, servos and sensors).

Step 1: Materials needed:

  • Two water bottles
  • Two simple dc motors
  • Two propellers
  • Isolating tape 
  • Box
  • Motoruino (or any other microcontroller and a h-bridge)
  • Battery

hi, are you aware that the props need to be at an angle to run and not straight.

nice idea though

i cant get it .

can you plz tell me how you instal sonar on motoruino.

plz
Thanks.how to increase the speed of the robot?

is it depend on microcontroller ?

It depends on your motors and on the voltage you give them.
XicoMBD (author)  altaf hussain3 years ago
where do you connect on the motoruino.

i mean to which pin

circuit plz.....
XicoMBD (author)  altaf hussain3 years ago
Pin 2
sensors are built in on motoriono. Or you attached seperately?.
XicoMBD (author)  altaf hussain3 years ago
I attached the sonar separately.
how it cost motoruini?.
XicoMBD (author)  altaf hussain3 years ago
how much it will cost?
thanks.

awesome man !!
would love to see live video too..
XicoMBD (author)  ameyanaik4 years ago
I hope I can upload one this week :D
Hi again! I would live to see this move! Video?
XicoMBD (author)  jweymarn3 years ago
The propellers I bought were too big, so I created a different boat. You can see the photos and videos here:http://www.franciscodias.net/robots/roboat
Nice!
how well does it work? does it go fast? if so how fast?

Good idea! Video?
XicoMBD (author)  jweymarn4 years ago
I'm waiting for new propellers to arrive.
When I got them, I'll shoot one video immediately.
