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:

Tool Picture
Hex M2 arm wrench arm M2 wrench
Screwdriver slotted small screwdriver_small

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.

:bulb: 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

:bulb: 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.

Assembly wheels

Flap

Quantity Part
1 flap_top.stl
1 flap_bottom.stl
1 Expansion board
1 USB cable
4 Hex M2 10mm

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:

  1. mount the flap covers on the nanosaur expansion board
  2. Screwing the 4 screw and stable fix the cover on the expansion board
  3. Pick your USB cable and pass it on the cover hole
  4. 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

:bulb: Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly

:warning: 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:

  1. Assembly the magnets**
  2. Take your two motors with cable wired
  3. Assembly the sprocket on the wired motor
  4. Pass for each motor cable on the slot
  5. For each motor press to the rear housing and align the motor border to the frontal cover
Assembly magnets Motor with cable Assembly motors front
Assembly front part

When is done the result will be like the picture below. Where the two cables are out of the frontal holes.

Final Nanosaur front look

Front and rear

Quantity Part
1 Motors block
1 base_rear.stl
4 Hex M2 6mm
2 magnet 4x2mm

:bulb: 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.

Tracks

Quantity Part
2 Wheel
2 Slider
2 track_print.stl
6 M2 nuts
6 Hex M2 20mm

This part is relative simple, you need to follow for each track this simple steps:

  1. Pass all screws to the all sliders holes
  2. Bring the wheel and assembly to the last housing following the picture below
  3. Bring the track and fit to the sprocket
  4. Bring the slider and wheel block and fit the track to he wheel
  5. Screw all bolts
Assembly track left Assembly track right - bolts

Wiring and board

Quantity Part
1 Body
1 Flap
1 NVIDIA Jetson Nano*
1 Adafruit motor control
8 Hex M2 4mm

This part need more attention, from this part, Nanosaur will be completed at 80%

Assembly board and wiring

There are few steps to follow to build quickly the body. Check the next gallery to watch all building steps.

  1. Bring the Flap and pass all wires in the slot in front the Body
  2. Assembly the NVIDIA Jetson Nano and screw all 4 M2
  3. Direct the adafruit power connector up
  4. Screw the Motor controller
  5. Wire the motor controller following the wiring page
  6. Assembly the Flap on the NVIDIA Jetson Nano connector

Components to pick up

Quantity Part
1 cover.stl
1 PI cam v2
2 oLED display - 128x64px
12 Hex M2 4mm
3 magnet 4x2mm

:bulb: Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly

:warning: WARNING Check the magnets orientation before to stick it!

We are looking the end of the assembling!

  1. Bring three magnets and stick on the cover folloing the picture below
  2. Screw two 128x64px oLed display
  3. Screw the PI Cam

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

:bulb: Hint If you don’t want to use the magnets, but the screw, follow the optional guide Screw Assembly

Assembly nanosaur head rear view

  1. Wire the two display using the cables from the Flap. Remember the GND is on left.
  2. Wire the PI cam on the NVIDIA Jetson Nano
  3. Clip the cover on the Nanosaur’s body
Wire the Nanosaur displays Wire the Nanosaur PI cam
Assembly nanosaur head - steps

Now clip the cover to body. Really simple the magnets will hold the cover without use any type of screw!
