I needed a project that would use all my servos, so I decided to make the do-nothing, worthless spider. If you have fischertechnik and servos to waste, this is the project for you! Really, this flopping spider makes for a great learning project. The main goal of this project is to teach the fundamentals of servos, synchronizing them, programming them, and understand the range and strength of servos. The results are very amusing!

Fischertechnik? What's that? 
Legos have bricks, K'NEX has blue and yellow connector rods, but what does fischertechnik have? In truth, it has way too many pieces to give names to! Fischertechnik is definately not as popular as legos or K'NEX, but I like it much better. It's very good for exercising building and construction skills. Here is an excerpt from Wikipedia on fischertechnik
"Fischertechnik is a brand of construction toy. It was invented by Artur Fischer and is produced by fischertechnik GmbH in Waldachtal, Germany. Fans often refer to Fischertechnik as FT or ft. It is used in education for teaching about simple machines, as well as motorization and mechanisms. The company also offers computer interface technology which can be used to teach the theory of automation and robotics."
I will be calling fischertechnik FT as mentioned above.

Here's a video of it walking.


Step 1: Ingredients:

  • Hot glue gun
  • Razor blade
  • Philips Screwdriver
  • Drill with 7/32 drill bit
  • Dremel with very tiny drill bit (a little bit smaller than the screws that come with the servo)
  • 6 AA battery pack and alligator clip
  • 8x micro servos and attachments
  • 30+ jumper wires or pin headers.
  • Breadboard
  • Arduino and power
  • Fischertechnik
<p>The way it looks at walks, it isn't exactly a spider, but an awesome robot dog!</p>
<p>Thanks for the diagram, I have one question please, can I attach the gnd of arduino directly to the breadboard?</p>
Yeah, why not? All grounds of any circuit always have to be connected to a common ground.
<p>Thanks a lot for the very quick answer! This solved the problem that I found in my spider robot, thanks again!</p>
<p>i finished making it thank you for the instructions</p>
Nice job!
<p>i love it, nice work </p>
nice work dude.
Oh come on! I don't care what it is! I know, spiders 8 legs. I used 8 servos!?
I love the sound it makes, nice work! <br>
Fischertechnik is hard to find, but if you need fischertechnik in Holland than you are welcome in my store and in my webshop: fischertechnikwinkel.nl
Well thanks kenyer! I'm really interested in the Robo Tx Explorer! I have to wait till I save enough money though :( which will be a while :'(
I love the sound it makes, nice work!
Haha thanks I kinda like it to! Unfortunately, it's bad quality, it's vimeo's new thing to make you go pro, they only let you have 1 HD video a week. Too bad I can't use youtube :(
Now try to make it with 8 legs!
I'll let you try it first :D
Haha ok, but if i try it'll exist definitely out of knex B)
I'm definitely sure you of all person could make it. I've seen your AMAZING ball machines! How do you do it?
Most important is... ... ... Patience! But off course you also need good ideas and very much knex. <br> <br>Hm, maybe I'll try to make a knex spider, but it'll be very difficult because i'll have to use many gears.
Wow. So, would you use all knex motors or servos?
Yeah, but it would be a real challenge to use one motor and then connect all the axles with gears and cranks. Like I said before, that would be very difficult.
An 8 legged spider would walk much better than this, because it wouldn't have to wobble! Thanks for the suggestion!
No problem!

Hola! Yo no hablo espa&ntilde;ol, estoy utilizando el traductor de google. Lo que usted ha dicho, gracias!
