Lego Mindstorms Nxt Robo Flush

Have you ever feel tired or lazy to flush your own toilet?
Why not try build a Robo Flush using Lego Mindstorms Nxt?

It can then help you to flush your toilet automatically.
Try imagine that if you have an automatic flush at home.
It will just be like those that are available at some public toilets.

This is a picture of how a Robo Flush can look like:

You can build a one that looks different as you like.

Lets look at some pictures with descriptions of how it works.

The Flusher:

The flusher is mounted under the toilet bowl cover. This is to make it more stable with the extra weight. No gearing is required for flushing the toilet. The energy generated by the Nxt motor is strong enough to flush.

The Nxt and Manual Flush:

The program for this robot will be more complicated if it is being programmed using the Nxt graphical language as compare to other programming languages such as Java.

The Ultrasonic Sensor:

What the ultrasonic sensor does is it will wait until it detects someone within the range in the program and then wait until that person is out of the range for detection. The Robo Flush will then say a polite thank you and flush the toilet after that.

Here is a video clip of the Robo Flush in action:

What do you think about the idea of this Robo Flush?

Not bad right?
Maybe you can try build your own one for the toilet at your house.
Haha...
