Xpider Fatty -- the smallest smart robot spider in the world

DFRobot Nov 09 2016 1511

This project is made by Roboeve in Instructables.  Following is the original text. 

The Xpider project is the smallest smart robot spider in the world. It used Intel Edison platform which is a tiny pc ( CurieNano would be also a good choice for this project). It contains some cool functions. For example, it can be controlled by your mobile phone, it has the camera, can make you watch through the FPV view on the robot, thus you will know what your pets seen. And also the camera can be used for computer vision to recognize some simple geometric pictures even human face.

And this version is a opensource version of our robot. The final version is crowdfunding on Indiegogo. 

And I embedded a graphical programming tool in the Edison platform. So you can program this robot yourself. The most funny thing is that you can train this small robot by some simple neural network algorithm. That make you can custom the only one Xipder for yourself. The main parts of Xpider were printed by 3D printer, PLA material. and the attached file is the stl file for all the printed parts. Please feel free to download it and make your own Xpider.


Step 1: Bom List


BOM list:

1. 3D printed Parts.
2. M2*5, M2*8, M2*10 screws and some nuts.
3. Intel Edison *1
4. small camera (any small USB camera (light enough), driver free, with UVC class) *1
5. N20 motors 310RPM w/Encoder *1
6. N20 motors 270RPM wo/Encoder   *1
7. 9G servo *1
8. micro motor driver  *1


3D print tips

All the stl file were attached in zip file. When you unarchive the zip file, you maybe find the file name end with number.
Download resources here.


Looking at the file name, if the file name contained "*3", that means this part should be printed 3 times. If the file name contained "need mirror", that means this part should be printed 2 times, and one should be a mirror part of another.


Step 2:


This is my main tool. since I can't find a M2 allen wrench head for this Bosch screwdriver, I cut off a M2 allen wrench, and insert it into the screwdriver. Lol...
notice the front side and the back size of the Leg A. Because the screws were axis for the Joint, these holes should be extended by a 2.1mm drill, to make sure the screws can cross the hols easily.


Step 3:


Connect Bottom and LegB, the screws should not be tight.
attach the Leg main part and Leg A parts. then attach the foot parts. Notice the difference between Foot A and Foot B, remeber to select a fit one.
attached Foot B to Bottom


Step 4:


attached the Leg C and Main Gear. Don't forget to extend the screw holes.
attached the main leg to Main gear. Notice that these three screws should not be tight.
notice the detail part


Step 5:


Attached all 6 feet, and this is back side view.

This is front side view.


Step 6:


Use the pillar to connect main gear and the bottom part like that:


Step 7:




Since the transmission shaft is too long, We cut it to 4mm.

And this is the spinning structure.



Step 8:


Connect two parts


Step 9:



Gear box part

combine them together.


Step 10:



Gearbox and frame

and Servo and Edison support


Step 11:


Camera and camera shell, since maybe you use different camera, so feel free to use the glue.

now you will get your own Xpider.
