Biped walks with eight servos

This tiny biped shows a lot of coordination in its movements. As you can see, eight servo motors account for the locomotion with an ATmega8 as the brains of the operation. Posts for the first and second generation of this little guy feature several videos. We gather that a spreadsheet is being used to tweak the preprogrammed movement sequences. Trial and error, that’s how humans learned to walk, right?

  2. markii says:

    i just realized that this looks like a floppy drive on legs :)

  3. Grumpy says:

    Awwwww …. thats cute :)

  4. Bergo says:

    Looks like an AT ST, those Ewoks won’t know what hit them! *pew* *pew*

  5. Finger says:

    Just add a wookie and you’ll save the rebellion.

  6. MrX says:

    He should increase the height of the robot so it doesn’t to bend so much to the sides in order to keep his center of gravity.

  7. someone says:

    I just realized what we have hips for ;P

  8. mars says:

    This thing is pretty cool

  9. maroc says:

    I was surprised that it didn’t fall down because of the way that it kept tilting nicely done.

  10. JBS says:

    I want to see a small army of these playing a soccer match!

  11. EdZ says:

    Anyone else reminded of “Batteries Not Included”?

  12. EFH says:

    This is nine different kinds of awesome.

  13. deathventure says:

    I dunno what’s worse, being taken over by robots, or being totally immobilized by the cuteness of a robot overlord.

  14. ThatGuy says:

    It’s Baby ED-209!

  15. supershwa says:

    @EdZ

    Yes, it does! It does look like the BNI aliens… Now it just needs to fly…

    He also has a ‘dancing’ video of the bot. There are better closeups of it in that vid starting at about 0:46

  17. dan says:

    AT-ST CHICKEN WALKER!!!

  18. sanchoooo says:

    This is so going on my birthday request form.

  19. googfan says:

    overkill much?

  20. McSquid says:

    I feel like he would be even more effective if given better grip. like if he was put on a carpet.

  21. Frost says:

    My girlfriend (Lithuanian) says that the name of it is “butthead 2″. !Terrific! ;)

  22. Hirudinea says:

    Yep thats a great baby AT-ST, if he’ed just lay off the booze so he could walk straight he’ed be perfect.

  23. Hirudinea says:

    Addendum:

    I just watched the little guy dancing, he’s pretty funky for a white guy, and if you moved the LEDs up and put a little smile under them his cuteness factor would go up by a factory of 10!

  24. Hotrodder says:

    ED209 meets batterys not included!

  25. The Ideanator says:

    You know what this needs? Lasers. ‘Nuff said.

  26. jeditalian says:

    @The Ideanator- thats exactly what i was thinking. it would be best to mount low because any weight on top would screw up the bot.
    but a little camera, mounted on servo/hinge rig so you can aim it with a joystick, and a blu-ray burning laser hack. all mounted at the robot’s ‘crotch’ area. to keep the center of gravity from being too high and maintain the balance.
    best hack i’ve seen in at least a month :D

  27. Josh says:

    Pew Pew Pew!

  28. Osgeld says:

    I want one!

  29. sasquatchking says:

    Awesome project!

    Just one suggestion. Could you not mount a controlled counter weight in the top section. The weight could swing side to side (controlled by servo) as the bot walks so that it does not have to lean so far.

    You’ve inspired me, I really want to build one of these.

    Always wanted a mini-mech.

  30. Drone says:

    In quantity this thing would come in around fifty bucks in cost.

  31. joe says:

    It looks like ED209 from Robocop :)

  32. andrew says:

    The legs always appear to stay parallel while walking. So, he could ditch the fixed connections between the top servos and the body in favor of hinges where the axis runs forward and backward. That way, the top platform would stay horizontal.

  33. robomonkey says:

    Add voice
    “drop your weapon, you have 30 seconds to comply”
    Oh and next gen, make sure it can do stairs…very important.

    Reminds me of one of the units from C&C tiberium sun. lol
