Introduction: How to Make the One Motor Walker (without Bicore)

Picture of How to Make the One Motor Walker (without Bicore)
Hi guys, maybe some of you are familiar to Jerome Demers one motor walker and  other one or  two motor B.E.A.M walkers. This project is highly inspired by those things. The idea  is to build  a walking machine that has similar gait to one or two motors B.E.A.M walking robots . The oscillating motions on the legs of B.E.A.M walker produces by an amazing small circuit created by Mark Tilden called bicore. In this project, the oscillating motion produces by linkage mechanism. The reason why I designed this mechanism because I had very basic knowledge about electronic back then, and I was really excited to be able to build a B.E.A.M walker. It was a big challenge that I finally completed through some experiments.

Step 1: The Mechanism

Step 2: Parts Needed

Picture of Parts Needed

(1x) full rotation micro servo
(2x) jumbo paper clips
(1x) small paper clip
(2x) terminal blocks (3mm)
(1x) terminal block (4mm)
(1X) used aluminium curtain rail
(1X) random plastic bar
Iron wire (2 mm)
Double-sided tape
Brass tube
(1X) small zip tie
(1X) battery holder (2 x AAA)
(2X) lock nuts (3mm)
(3X) nuts & screws (3mm)
(1x) nut & screw (4mm)
(5x) washers (3mm)
(1X) washer (4mm)

Step 8: Mounting the Legs

Step 9: Linkages

Step 11: Final Touch

Finally just connect the wire directly from  servo to batteries, then the robot will roam your living room :)

I did it! thanks for the fantastic idea, Burhan. I used some different materials and I added laser eyes. But basically is your concept. Awesome!

That looks great! Really neat work. Thanks to you too :)

I'm fan of your work. I love your YouTube channel. Your walking robots that avoid obstacles are my favorites!

Beautiful and clever, I built a cicada robot with 2 servos,
here's a video:

Thanks :)

Thanks so much

Well, I could repair the ant. It have problems of traction in back legs and too much swing in forwards leg.

Can someone point to a source for the Continuous Rotation Micro Servo?? Major thing needed!!


hlicera (author)TerryKing2014-05-18

You see this one...?

hlicera made it! (author)2014-05-18

Hi I made this prototype using a computer part like PPSailor, but it cant walk on forward direction and tend to round ay rigth. Can anyone hepl me?? Thanks!!


hlicera (author)2014-05-18

Hi, I made a prototype but it cant walk in forward direction, and tend to round to the rigth. Anyone can help me, thanks

Hi ! Burhan !

Simple Projects are the most attractive and beautiful.
I had fun building this instrutctable you've shown.
Sending pictures and video of my model.

I really love this. I made one over the weekend and although there wasn't much in the way of explanation, I managed to get walk. I actually enjoyed trying to work out and solve the few places in the build where I couldn't quite work out what you did.

Great job!

Here are a couple of pictures. I have changed the legs now and they look at little like the ones in your YouTube clip. Do you have any plans to do another Instructable soon? I'd love to see how you did the avoidance one.

where can I buy the continuous micro servo (I live in Ontario Canada)

saurav.saxena (author)2014-01-01

Awesome...!! Great Job Dear..!!

Thanks so much!

SVAsciencegroup (author)2013-12-20

can it be moved in all directions !

I believe there's possibility to make it move in all directions. So far I've been making the version that backups and the version that turns to one direction when it hits obstacles.

Fantastic tutorial ! Well documented and I love the image annotations with the 'tools' needed. Best one I've seen. And what a great robot ! Simple yet so effective :)
Thanks and keep up the hard work !!

Thank you very much!

burhan saifullah (author)2013-12-16

Guys, thanks so much for your appreciations, supports and valuable suggestions. people like you really give me motivation to do even better thing in the future :)

Want to add to the posative vibe, absolutely love this!

M.C. Langer (author)2013-12-15

I love it! Like you, I'm not good in electronics, so I have to be creative. Favorited and voted! fantastic!

Wareneutron (author)2013-12-15

Nice job.... you are truly a robot maker for me... nice mechanism>>

caarntedd (author)2013-12-15

Fantastic and well presented! Favourited.

hectdiaf (author)2013-12-14

you could design the pieces in 3D to print and it could be a great idea for share.
congratulations, your robot I liked very much

kenbob (author)2013-12-14

Love the simplicity and effectiveness. Beautiful instructable as well!

rastna (author)2013-12-14

this simple nice

ezbuzzit (author)2013-11-19

That is freaking cool. Thanks for sharing.

Thanks to you too :)

andrea biffi (author)2013-11-19

nice pictures and details, maybe a little more explanations would be great..

Thanks so much for the suggestion, I agree with you. I just need to encourage myself to do it cause I always feel I'm bad in making explanations :)
