Introduction: 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
(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 3: Parts Maps
Step 4: Tools
Screwdrivers
Pliers
Hot glue gun
Multi function tool
Scissors
Step 5: Body
Step 6: Front Leg
Step 7: Rear Leg
Step 8: Mounting the Legs
Step 9: Linkages
Step 10: Mounting the Linkage
Step 11: Final Touch
Finally just connect the wire directly from servo to batteries, then the robot will roam your living room :)

Beautiful and clever, I built a cicada robot with 2 servos,
here's a video: https://youtu.be/OmkWELCOA18

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!!
Thanks!

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.

can it be moved in all directions !
Reply 9 years ago on Introduction
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 !!
