What does it do?

Navigate around via ultrasound finding objects to play on.

After seeing fritsl's Yellow Drum Machine in action, I decided that I needed to build a robot like that. It just looked so fun and to tell you the truth - it has been. Here are a few pics and a video about my progress.

What does it do?

pick some small objects

well, it's my first manipulator. ist's nothing special, but it's better than everything i did with this metal contruction box i have. it would be great, when there is someone who wants to help me, so i can control it from my pc, but you have to know ,that i'm totally new in this stuff(but i work hard to improve myself). i work on a new project wich shoud be ready after some months, but i'll probably make a video before that.

The way we walk...

What does it do?

Walks straight ahead

This is an attempt to build a walking biped with only 4 servos, since that's what I have left right now. Since I don't have any video recording equipment right now, I'll try to describe how it walks. It start by tilting left to put all the wight on the left foot and lift the right foot. This is done by turning the left foot servo to the left, while turning the right foot to the right to support the robot as far as possible in the tilt, like this:

How to build your first robot - Part III - Get a grip!

fritsl — Fri, 18 Apr 2008 10:23:08 -0400

This is part III of a series I call “How to build your first robot”.

This part is not so much instructions of how to build & program, that was in Part I-II.

To finalize Part I-II, I will just say; I may put “construction time” to a few hours when entering a robot. And it is possible to make a robot in 10 minutes if you have the materials in front of you.

What does it do?

Pushes itself around, freeweelin'

This was in a series of robots I made when I was really fond of the idea that instead of giving a robot wheels with traction, it should just be "something" that could push itself around on free roling wheels.

Hard to explain, but take a look at this:

It is tha base of an old Nielfisk Vaakum Cleaner.

Wouldn't it be fun to have a robot placed on top, with arms that it could push itself around with? (whatch video to catch my drift)

I want to do more of that kind some day soon ;)

I mainly show you this because of the video; I hung up a camera behind my head, and a remote in my hand to start it every now and then - just as an experiment, I would love to see other peoples ways of building, filmed that way :) (I know I am a mess, btw)
