this is BoB, my version of the 4 dof mini biped.


his goal in life is to walk around and take over the world one 3d printer at a time.

at this time the 1st prototype is under construction. the plans are to use a ping for vision, dagu mini driver for a brain, and 4 9g micro servos to shuffle around.

my real goal with this is to see people build and release their own bobs and make their own add ons.

3d assembly made in solidworks 2010

awesome 3d parts thanks to mr. FrankNeon

Bob's first add on. 


more to come when i get the 3d parts in the mail.



got the package yesterday and got him together last night. i did need to sand the servo spots a bit to get the servos in but it has resulted in a screw free fit. same witht he ping in his head.

I'm working on a very tiny version of Bob, based on ultra-micro servos and a ESP8266 module. It goes well, although I'm still waiting for a tiny distance sensor to arrive... http://sheep.art.pl/Micro-Bob

Deshipu, are running this all from the esp8266? Awesome stuff! I noticed you have not posted it here on LMR and your previous bot(s) seem to be gone. Hope no one chased you off... I would love to see μBob here on LMR.


Dear: K120189

How do you build bob using recycled parts. You see I am trying to build bob but I don't own a 3d printer but I have one heck of a recycle bin. It has most junk you would be surprised to see whats in there. I have a cambels soup can and I want turn it into a bob. Any ideas.

From: Noah

PS: The dimensions of the can are a diameter of 4" and a length of 6" is that good enough?

Finally I want to add my BoB as well.

Here you go little Purple BoB

Found another blog on BoB, probably prompted by my MAKE post, but providing good coverage and addiitonal info and insight.


Hey, all. I'm writing a post for MAKE on BoB the BiPed. I'm including pictures from some of the many copies and adaptations other LMRians have done, including:

  • Silent BoB by JAX
  • Creepy BoB by hoff70
  • Yellow BoB by isotope
  • Grey BoB by Aval
  • Blue BoB by TinHead
  • FrankenBoB by RobotFreak

I'm trying to contact the folks above, just to be sure they are OK with having pictures of their bots included. I'm assuming most LMRians would be OK with it, but if anyone has a problem with me using their pictures, just let me know. 

UPDATE: You can find the post on MAKE here.

How about hoff70's DDHCBoB?


P.S.: This one also features the BasWheel (my creation)
