The assembly of 3D fish is introduced as follows:


1.Component
Beetle BLE - The smallest Arduino bluetooth 4.0 *1
9g micro servo (1.6kg) *2
Gravity: Digital PIR (Motion) Sensor For Arduino *1
Bluno Beetle Shield *1
Battery Holder *2
5mm LED Pack
Cardboard (size 25*15)
Overlord 3d printer

2. Print the enclosure components in form of 3D



3. Firstly, connect the “fish skeleton” and check fish head and body.


4. Connect the fish head and fish body with two screws. Directly tighten the screws to allow the fish head to move freely!

5.So far, the fish skeleton is assembled!

6.Two small parts similar to connecting rod are provided! Such two parts are used to connect the steering engines of fish head and tail.

7. After the fish skeleton is assembled, mount such two parts as per the position below.


8. Mount the open source hardware module and battery. Firstly, mount the main control Beetle and tighten it with screws.


9. Mount front and rear steering engines


10.Mount the pyroelectric infrared sensor



11.Now, the fish looks like this.


12.Then, mount the battery stacks on the front and back of fish skeleton.


13.Then, connect the lines of sensor and steering engine according to the structure defined in the software.


14. After the open source hardware is installed, put the “jacket” on the fish. Firstly, look the appearance of such “jacket”.


15. The fish head and fish body are in symmetrical structure. There are four magnets on both sides, so they can be easily connected. There is a small hole on the fish head for mounting the fish eye (LED).


16. No screws are required for enclosure. Directly cover it on the enclosure at the other side.


17.At last, open Beetle control switch and mount the last enclosure, and place the fish on the printed base. If the fish is unstable, paste it with plasticine.


Done！
