I built a robotic duck (scale 1:1), which looks and behaves like a real duck. My White Duck is able to walk around by herself and she lays eggs in her nest! But is she clever enough to keep them….?
About this creation
To build the White Duck I used Lego NXT, Technic bricks and also ordinary bricks and slopes.

White Duck info
You can find white ducks (Anas platyrhynchos) all over the world. They live in ponds, marshes, lakes and ditches. When the Duck build her nest she lays 8 till 10 eggs. She needs 4 weeks to hatch them out. The natural enemy from the Duck is the rat. He steals eggs from the Duck nest to eat them.
To make my robot looks like a real duck I made photo’s from ducks in my street. I printed a few photos in scale 1:1. I used these photos to make the right silhouette.
Duck technology When you make a robotic animal it’s important that she reacts to her neighbourhood and other animals. So I used a ultrasonic sensor to give my Duck “eyes”. With this sensor the Duck is able to avoid objects. With a color sensor my Duck can see dangerous places which are marked yellow. With the same sensor the Duck can follow the blue line which brings her to her nest. When she finds her nest she lays her eggs.
To let my Duck interact with other animals I work together with Egol Vuurzoon. He made a rat which steals the eggs from the duck nest. Luckily there where two eggs hatched out. I built these two duck chickens with Lego power functions. For more info about these animals, see the links below.
Technical features include:
1. moving random at variable speeds.
2. avoiding objects with ultrasonic "eyes".
3. returns when crashed into object, to set it selves free.
4. avoids dangerous area's marked by yellow line.
5. creates random real duck sounds as recorded.
6. is searching for her nest to lay her egg (following blue line)
7. lay a egg when she has found her nest. controlled by motor A
8.White Duck shape & looks sculptured with Lego bricks; mainly white plates, bricks and slopes
9. Built in modules for easy access (battery change, modifications, repairs).
I hope you enjoy my duck.
very clever! as an nxt owner,[without a functioning prototype]i really can appreciate the design ,and effort here! it does nt sound easy to make it smoothly follow the lines.this was my design idea as well,tapes on the ground,
for infos,very astute,enclosed environment? very good idea! as to the cosmetics,they re
quite convincing,it s very ambitious to coordinate mutiple robots,an achievement in itself! congratulation! excellent work!
Hee ik had deze even gemist. Jullie waren opeens niet meer een van mijn favoriete bouwers. Vreemd. Maar wat een geweldige creatie. Jullie combineren steeds een goede techniek met een mooie vorm. Ik ben fan.
