Hi there,
I'm starting in the world of electronics and computer interaction,
building my own circuits connected to different input/output of the PC,
etc...
My main goal is to have the computer control something in reality.
Robotics. And my main problem is I lack the skill about crafting robot
parts that will be attached to motors to create movement. I don't have
any tools and have no experience working with any kind of materials.
I'm looking to make a solid robot, something that can potentially
survive a crash (in case a remote controled car!) or survive anything
wrong that can happen to it, the structure would need to be solid. My
budget is pretty low and yet, I'm probably able to make some money
available for that hobby. I don't know what materials I can use that
suits my situation and needs, something that would not require the
whole workshop to make the part, something that could be light and
solid (or heavy), yet it has to be easy to use.
My post is not directly about robotics and might have better feedback
in other newsgroup, can you tell me which, and if you know a website
that can get me started, please tell me!
Thanks for any help in advance!
Simon

OK, can I buy them ready-made?? ;-)
I would need the following: 1-axis articulations (shoulder), rods of a
certain length, rod motor rotary around its axis(like a drill, but
smaller), wheels and gears, pistons?, what else... sensors (that's for
a different thread, I'm reading on it already).
Thanks for the help,
Simon

Please log in for more thread options I am certainly not an expert, but since no one else replied, I will try
to give you some useful info.
Of course a kit is the best place for you to go. There is a lot to
learn in robotics and you can't learn it all at once. The right kit
will let you use the knowledge you already have, and then stretch you a
bit further.
I think your existing understanding of electronics will be a valuable
asset.The computer hardware and software interface knowledge will be
especially useful.
But, all that said, the best I can do is refer you to some on-line
stores that a good selection.

components)

Please log in for more thread options Simon, Do you have the programming abiltity to do this project where
building it would be your
only short coming? ( the idea intrests me, but all my attemps at shared
programs to run robotics elsewhere have failed thus far)
now, you say you have nothing? how much nothing? A screwdriver?
Soldering Iron?
hacksaw? anyways, what are you trying to do exactly.( I mean, describe
the timing, motions and events you want to occur in a specific device.)

Well, I'm an excellent C/C++ programmer and I've been reading about
using the different ports on the computer to have interactivity with
the outside, I'm thinking on using the parallel port for a start and my
long term goal is to get to make my own PCI interface card.

Yea, kinda nothing. I mean, I do have one of those 10-in-1 screw
drivers and that's about it, not even a hammer! (Yea, I'm still
young!)
About the robotics I'm going toward, I'll be interested to try
everything, starting from the simplest rotary motion like a wheel in a
car, then trying more advanced mechanisms like transfering the rotation
onto a different axis, a changing angle between the two axis of
rotation, etc, etc, etc...
It all depends on the project, and right now, there is no "starter"
project, I was looking for your comments and I think starting with a
kit will definately be the way to go. It will work and I can possibly
hack it to work my way, then try to interface it with my parallel port,
eventually craft parts made of plastic or metal with the same design as
the kit has, maybe bringing my own modifications...
So, yea, I'll invest in a kit, and... then, I'll have precise questions
for you guys! ;)
Thanks a lot!
Simon
