Walker2

This is my second BEAM walker. It works better than the first one.

It uses two mini servo's and is powered by 4 small batteries 750 mAh. I've used the same electronics as was used in my first one, just some minor changings were needed for adjusting speed and backup time. Just take a good look at the pictures, and you'll see how simple it is to build one of these guys.

Inside the servo housing I've mounted a BAL 6686. It's a really small motor drive and comes out of old "normal-big" servos used in the first Beam walker ( just below this small walker).

This is Walker2 with some of his/her neightbours !

 


Walker

This is my first attempt on making a walker.
At first I didn’t want to hack my servos so I build an electronic circuit that makes 4 different pulses, for each servo two. With some logical electronics this gives a walking possibility.
It works but isn’t BEAM. It can reverse, but as you can see in the picture the feelers aren’t mounted yet.

Later I rebuild it, and know it a thrue Beamer.

This is a Hexapod I've made in 2001.

For more information look here.

 


Hexapod 1.

This bot is powered by twelve servos. It still isn’t ready yet.
To make it walk I want to use a C-control basic computer.
Programming is done at the PC in a language that looks like basic, easy to understand.
After programming you’ll be able to send it to your C-controller, this can then operate stand-alone. At this point I cannot decide, shall I make it so it will find its way all by itself, or by RC control. It gets different speeds, forward, backwards, turn left, turn right and turn on one place.

Flatfoot

Flatfoot is my first Bipede, but I'm sure it won't be my last. I really like this guy. It is very easy to build with only minimum tools needed. Just 14 pieces of aluminium or plastic and some screws. The electronics are my own design. Not BEAM but logical integrated circuits. Just imagine that you can build a "human like walker" with so few.


Hexapod 2.

This one is powered by just three power servos, each with a torque of 9,8 kg/cm.
It can do the same movements as hexapod 1.
I also planned to control it with the C-controller, influenced by RC.

Zoid

A toy that can walk, it is spring-powered.
I think its almost twenty years old.



Mini walker

A first attempt to make a walker as small as possible. The electronics are just a transistor flip-flop, with a H-bridge.
