Introduction: Xpider Fatty -- the Smallest Smart Robot Spider in the World

Picture of Xpider Fatty -- the Smallest Smart Robot Spider in the World

The Xpider project is the smallest smart robot spider in the world. It used Intel Edison platform which is a tiny pc. 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 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

And this version is a opensource version of our robot. The final version will crowdfunding soon, please support us by liking the facebook page:

Step 1: Bom List

Picture of Bom List

BOM list:

1. 3D printed Parts.

2. M2*5, M2*8, M2*10 screws and some nuts.

3. Intel Edison (buy) *1

4. small camera (any small USB camera (light enough), driver free, with UVC class) *1

5. N20 motors 310RPM w/Encoder (buy) *1

6. N20 motors 270RPM wo/Encoder (buy) *1

7. 9G servo (buy) *1

8. micro motor driver (buy) *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.

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:

Picture of

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:

Picture of

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:

Picture of

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:

Picture of

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

This is front side view.

Step 6:

Picture of

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

Step 7:

Picture of

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

and This is the spinning structure.

Step 8:

Picture of

connect two parts

Step 9:

Picture of

Gear box part

combine them together.

Step 10:

Picture of

Gearbox and frame

and Servo and Edison support

Step 11:

Picture of

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

now you will get your own Xpider.

And we will release the electronic part soon.

Fantastic design, love the Xpider's scuttling motion and also looking forward to your Mark III. It might be my computer but some leg pieces and gears are missing from the above Zip file?
