A few time ago, i found out a 3d printed Micro-Hexapod on Thingiverse.
I started to work on it in the following ways:
- create new accessories/components 3D printable
- explore the possible ways to drive this hexapod.
Here the results:
- a parametric battery holder that fits perfectly on it, without screws
- a parametric pen holder that transforms this hexapod in a drawbot!
- you can drive this hexapod via bluetooth, from your smartphone (here you can find also an Android App!) or from your PC
- you can drive this hexapod by using your nunchuk
- the hexapod can act as a light follower (thanks to 2 LDR)
Now you'll see how to build a full working hexapod!
Step 1: BOM
You need the following PRINTED PARTS:

files: body.stl & legs.stl
1x battery clip for 4AA

1x Pen Holder

files: PenHolder_hexapoduino_front.stl & PenHolder_hexapoduino_back.stl
You can eventually print an insect head / smile / other to put in front of the hexapod, to personalize it.
You need also the ELECTRONIC PARTS:
1x Arduino Mini or Arduino UNO (or compatible)
3x Microservo 9G
4x AA batteries (better if rechargable)
Then, if you want to make a light follower robot, you need:
2x 10K resistor
If you want to drive you robot using a nunchuk, you need:
1x nunchuk adapter (you can buy it or you can remove from an old / broken wiimote)
1x 10K resistor
If you want to drive you robot via bluetooth, you need:
1x HC-05 (or compatible) bluetooth module
1x 2K2 resistor
1x TS2950 33 (or compatible) voltage regulator
