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

plz

[altaf hussain]

Thanks.how to increase the speed of the robot?

is it depend on microcontroller ?

[XicoMBD]

It depends on your motors and on the voltage you give them.

[altaf hussain]

where do you connect on the motoruino.

i mean to which pin

circuit plz.....

[XicoMBD]

Pin 2

[altaf hussain]

sensors are built in on motoriono. Or you attached seperately?.

[XicoMBD]

I attached the sonar separately.

[altaf hussain]

how it cost motoruini?.

[altaf hussain]

how much it will cost?
thanks.

awesome man !!
would love to see live video too..

[XicoMBD]

I hope I can upload one this week :D

Hi again! I would live to see this move! Video?

[XicoMBD]

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!

[jackjackattack]

how well does it work? does it go fast? if so how fast?

[jweymarn]

Good idea! Video?

[XicoMBD]

I'm waiting for new propellers to arrive.
When I got them, I'll shoot one video immediately.
