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

<p>how ll i stear it</p>
<p>How do I maintain the orientation of the motor?</p>
<p>For some reasons I couldn't open the MiniRobot.pde.. </p>
Awesome idea. Very simple method for achieving something great!
<p>what is the program for it to work? </p>
<p>Does it actually work?</p>
<p>hai dud I cannot find how to use the MiniRobot.pde</p>

<p>hi, are you aware that the props need to be at an angle to run and not straight. </p><p>nice idea though</p>
i cant get it . <br> <br>can you plz tell me how you instal sonar on motoruino. <br> <br>plz
Thanks.how to increase the speed of the robot? <br> <br>is it depend on microcontroller ?
It depends on your motors and on the voltage you give them.

where do you connect on the motoruino. <br> <br>i mean to which pin <br> <br>circuit plz.....
Pin 2
sensors are built in on motoriono. Or you attached seperately?. <br>
I attached the sonar separately.
how it cost motoruini?. <br>
Have a look here:&nbsp;<a href="http://www.guibot.pt/motoruino/" rel="nofollow">http://www.guibot.pt/motoruino/</a>
how much it will cost? <br>thanks.
awesome man !!<br>would love to see live video too..
I hope I can upload one this week :D
Hi again! I would live to see this move! Video?
The propellers I bought were too big, so I created a different boat. You can see the photos and videos here:<a href="http://www.franciscodias.net/robots/roboat" rel="nofollow">http://www.franciscodias.net/robots/roboat</a>
it has any video that show how it works!
how well does it work? does it go fast? if so how fast?
Good idea! Video?
I'm waiting for new propellers to arrive. <br>When I got them, I'll shoot one video immediately.
Hi Xico! BittyBot from LMR! Hope you win! ;P
Thanks BittyBot!
