Assembly
If you are here, you are ready to mount nanosaur!
There are few steps to follow to mount nanosaur only using the tools in list, remember to collect and buy all components listed in the Bill of Materials
We can split the nanosaur assembly into four parts:
After mounts these three parts you can complete the nanosaur assembly. You need only:
Hint To simplify the assembly, dry-fit of all screws after 3D print
Power Bank holder
| Quantity | Part |
|---|---|
| 1 | pb_holder.stl |
| 2 | magnet 4x2mm |
Stick the magnets is optional, if you want only screw the power bank holder, skip thi step.
Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly
Wheels and Sprocket
| Quantity | Part |
|---|---|
| 2 | wheels.stl |
| 2 | sprocket.stl |
| 6 | Ball bearings F686ZZ |
Hint If you are building with ball bearings with size ID 1/4in x OD 1/2in remember to print the equivalent sprocket and wheel
The two wheels and the two sprockets are simple to assemble. Pick it up the wheels and assembly all ball bearings following the pictures below.
Flap
| Quantity | Part |
|---|---|
| 1 | flap_top.stl |
| 1 | flap_bottom.stl |
| 1 | Expansion board |
| 1 | USB cable |
| 4 | Hex M2 10mm |
Hint To simplify the assembly, dry-fit of all screws after 3D print
To assembly the flap, is relative simple, follow the pictures below, you need in the beginning soldering the Expansion board, when is done, you should follow these simple steps:
- mount the flap covers on the nanosaur expansion board
- Screwing the 4 screw and stable fix the cover on the expansion board
- Pick your USB cable and pass it on the cover hole
- Screw the cables on the connector (Hint: the positive is external. There is a little (+) print on the expansion board)
When the flap is fully mounted you will obtain something like the picture below
Body
Now we are assembly the robot. We are ready to see finally Nanosaur riding on your desktop. These steps are simple to do and don’t need a lot of time to do it.
Motors block
| Quantity | Part |
|---|---|
| 1 | base_front.stl |
| 2 | Sprocket |
| 2 | Pololu Micro Gearbox |
| 3 | magnet 4x2mm |
Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly
Hint To simplify the assembly, dry-fit of all screws after 3D print
WARNING Check the magnets orientation before to stick it!
To assembly the front Nanosaur block, you will need to follow only the steps in these pictures, where:
- Assembly the magnets**
- Take your two motors with cable wired
- Assembly the sprocket on the wired motor
- Pass for each motor cable on the slot
- For each motor press to the rear housing and align the motor border to the frontal cover
When is done the result will be like the picture below. Where the two cables are out of the frontal holes.
Front and rear
| Quantity | Part |
|---|---|
| 1 | Motors block |
| 1 | base_rear.stl |
| 4 | Hex M2 6mm |
| 2 | magnet 4x2mm |
Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly
Now bring the rear base of Nanosaur and with 4 screws assembly the cover, after that stick with glue the two magnets in their slots, following the pictures below.
When you assembly the rear part, the motor will be like the picture below.
Tracks
| Quantity | Part |
|---|---|
| 2 | Wheel |
| 2 | Slider |
| 2 | track_print.stl |
| 6 | M2 nuts |
| 6 | Hex M2 20mm |
Hint To simplify the assembly, dry-fit of all screws after 3D print
This part is relative simple, you need to follow for each track this simple steps:
- Pass all screws to the all sliders holes
- Bring the wheel and assembly to the last housing following the picture below
- Bring the track and fit to the sprocket
- Bring the slider and wheel block and fit the track to he wheel
- Screw all bolts
The result will be like the picture below
Wiring and board
| Quantity | Part |
|---|---|
| 1 | Body |
| 1 | Flap |
| 1 | NVIDIA Jetson Nano* |
| 1 | Adafruit motor control |
| 8 | Hex M2 4mm |
Hint To simplify the assembly, dry-fit of all screws after 3D print
This part need more attention, from this part, Nanosaur will be completed at 80%
There are few steps to follow to build quickly the body. Check the next gallery to watch all building steps.
- Bring the Flap and pass all wires in the slot in front the Body
- Assembly the NVIDIA Jetson Nano and screw all 4 M2
- Direct the adafruit power connector up
- Screw the Motor controller
- Wire the motor controller following the wiring page
- Assembly the Flap on the NVIDIA Jetson Nano connector
When the body is assembled looks like the picture below
Head
There are many options to assembly the nanosaur head. Follow the instructions from the cover your already printed.
Hint A new cover for OAK-D lite will coming soon!
Full assembly
Finally we are at the last step to build nanosaur, we only need to mount the head and the nanosaur, let’s go!
Build nanosaur
| Quantity | Part |
|---|---|
| 1 | Body |
| 1 | Head |
Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly
- Wire the two display using the cables from the Flap. Remember the GND is on left.
- Wire the PI cam on the NVIDIA Jetson Nano
- Clip the cover on the Nanosaur’s body
Now clip the cover to body. Really simple the magnets will hold the cover without use any type of screw!
Assembly power bank
| Quantity | Part |
|---|---|
| 1 | Body |
| 1 | Head |
| 1 | Power Bank holder |
Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly
Nanosaur is assembled, need POWER! 
- Slide the power bank following the picture below
- clip the power bank holder
- Plug the usb connector to the power bank
Done
Finally nanosaur is ready to be installed, let’s go to flash the MicroSD and install all software
