//it was built earlier itself. nothing much to say. enjoy.

On request from Lumi and others, well let me explain it. The box is from our car. It contained a relay and some  damaged circuit, most probably to control the turning lights. I removed all those things. The linkages, i got some plastic piece(small sheet sort of). As far as i remember, it was from the back cover of old tubelight choke. Heated up the blade of a paper cutter and cut them in shape. They left some black marks. so with an unheated cutter gave the finishing. if you are planning to make one, better use hack-saw cutter, but be careful of the plastic dust. then there are 2 tiny pulleys. The rest, you'll have in your home.

I opened up a brushed motor from toy car. carefully beat it using pliers to move the armature in somewhat middle position. The purpose was to have protruding shaft from 2 sides not just from one side. then it was reassembeled.

Then made the linkage connection as shown in the image. a similar one for the other side but while conecting the pulley to the motor shaft, attached it at 180 degree to earlier one. For making the linkage connection to body smooth, i inserted a pen refill. Then connected the linkage. Connections were made using steel wires.

a 9 v battery and multicolour led came in. but the motor seems to soak up all the pocurrent. I had to use fresh batteries to get it runnung. maybe cell phone batteries would have done it. have a close look at the video.

 

runs

  • Actuators / output devices: legs controlled by motor
  • Control method: out of control
  • CPU: brainless
  • Power source: 9v battery
  • Sensors / input devices: deaf but not dumb
  • Target environment: it has no target

One time again, extremly well done, Junkster.

I definitively love the way you use CD-reader and floppy-reader, without any floppy or CD …

How did you manage to spend 2$ ? You boughts led or battery or soap-looking box ?

Bravo !

That is another examle that

That is another examle that robotics is not limited to high tech material and that common material is a good choice to build something.

But you write “nothing much to say”, whith that I disagree. I am sure many of our fellow LMRians would like to see how you manage to build the things you built. How you connect the links from the motor to the legs, what is the challenge by using that kind of components/material, what tools are you using? See? That questions need to be answered to inspire more beginners and let them know that they just need to start with something without the fear of breaking expensive gear they bought…

Thanks for the additional

Thanks for the additional info. I did not know that the axle of that motor can be moved. That’s a good idea if you need the shaft on both sides.

9V block batteries are not suitable for applications with a high current demand. cell phone batteries would be are much better for that walker. Keep your postings coming, me and I am sure everybody else is interested in this kind of work.
