Hey guys, I have 5 standard servos sitting around here and I had some inspiration to make a worm robot.
I did some quick sketches and made a model out of cardboard. Its going to pick up its tail first and put it on the ground closer to body, then the wave just travels down the body eventually to the head.
With only 5 servos it has 6 segments, 4 up/down pivots and 1 left/right pivot in the middle for turning. Turning might be tricky, so Im going to mock up a better version with packing foam and play around before commiting to it.
I've been wanting to see something like this for a long time, and have never been able to make it.
A couple of people probably know games like WarHammer.
For those who dont, WarHammer is a stratagy game played with mini figurines, out of a Fantastic/Midivel times. Those figurines are generaly abaut an inch (about 2.5 cm) high, unless somekind of Troll or something.
So i was looking at some flying robot designs, just out of curiosity. I ruled out helicopters and planes: they require too much precision in crafting and are too complex.. But alternatively an airship could probably be built :)
I've read on wikipedia that a square meter of helium can lift about 1 kg. A square meter means a big balloon, but a Kg is plenty of weight for electonics!
If you use light components, you can probably stay under 0,5 Kg or even less.
couple of months ago, i knew i want to start to make things move, work, interact, etc... and i´ve made my first order, so i bought this lovely motors.. i never dreamed that i would need gears, or transmissions boxes.. so it was a big dissapointment when I found out that a motor woudn´t drive any wheel just because it is a motor...
so, I want to give life to this guys, and without having gears.. anyone have ideas or suggestions for what can I do with these? :)
Hi, I've been thinking on building a night and day vision camera. I think its very straight forward, but I just wanted to have a look at your personal opinions before going any furtherer.
The idea is very simple: As you probably all know, digital cameras are able to "see" the visible spectrum, but also, some frequencies higher (I think), and lower. You can try this by pointing with a remote control to your camera, you will see a white light.
Hi all, I am so excited about this. It may not be much to anybody else, but to me it is!
You all know how we only have the IR's or the Ultra sound to work with when we want to check distance? Yeah, if we have millions we can also get a camera or two, and laser range finders..
However, I wanted something cooler.
This is not that, I am sorry.
However, I am working on something cooler (I hope, but it may be far fetched), and when doing so, as a spin off I made this.
I have been thinking about this, any ideas? i mean like what components i could use, using radio frequency not rfid or neither gps. could really appreciate help.
Baiscally it should have a screen where i could track my robot within 100m? try to keep it cheap i guess
update
It is supposed to be something like a phone where it has a screen and i can see the object like a radar. it would also make me able to flash an led at the other end of the wireless device p
So I started doing a search of toys, mainly rc, to use as a base platform for a random project. I wanted it to also includ some features that would be useful or have at least some potential, and I came across this little gem.
Reading about all those lucky people that have access to a laser cutter, i was wondering: can we make one? I mean, build a custom (cheap) laser cutter?
I think it should be something like a plotter, so with a couple of fine-grained steppers and a frame structure (maybe some old scanner) that should be ok.
The problem is the cutting :P where can one find a good laser? i thought about CD-Writer but they have about 100 mW.. I don't know, maybe it's enought for a small dark acrylic sheet.. But i think the optical stuff won't fit :)
I've spent most of today daydreaming about the possibility of modifying the 'start here' robot to include some kind of sesiivity to sound.
My idea is to have 2-4 microphones around the robots body. When the robot hears a sound, he compare the levels between the sensors, and turns to face in the direction of the strongest level.
this way you could clap to draw your robot's attention, and make him act a bit more like a living thing.
That's the idea...now the technical side....how do i interface a number of microphones to the PICAXE's analogue inputs?
