how to get into robotics?

Lego technic is a great simple building system quick and you can buy (at a hefty price) the programming system.

A cheaper way is go the microprocessor route - You don't say where you are but in most parts of the world you can get Picaxe micro systems.

They sell all you need for robotics up to pretty complex concepts.

their programming system is free to down load as are their manuals and MUCH information about their kits.

their support forum is also particularly good.

Start simple - get used to programming - a simple 08Ms and a bought programming PCB (makes life easier at first) a few LEDs and resistors and you are started.

Search their forum for starters equipment.

As a transplanted Czech I want put my two koruna in here.
Karel Čapek, a Czech writer coined the term "robot"
And shire lad.... you should follow through what is outlined by these nice people.
Or you can stand in front of a mirror and Say,
Karel Čapek... Karel Čapek... Karel Čapek
Where upon Čapek will appear...
....and turn you into a pic of a early robot in his book :-)

i find this useless however you amuse me by quoting my username BRAVISSIMO

Thanks for the kind feedback,
I didn't think you scared easy.

One thing I like the most about learning to program is :
I don't have to copy all the detailed discreet IC circuits in an ible
I can use a single microprocessor to replace all the wiring.

And if I screw up... well just change some program instructions.
I've got to admit that's part of why I drifted away from the chip-design end of things, through design tools, and back out to software.

And why I try to avoid doing any analog electronics that can't be implemented using an op-amp. Near-ideal behavior, high-impedance inputs, and plug-in solutions make life MUCH easier.
Yea... Iv never been too good at analog, but a buddy of mine is super hot
on the subject he explained a lot of his designs how and why they worked.
I built stuff and learned a lot of what not to do, plus there is always W. Jung... LoL.
Yep. The IC Op-Amp Cookbook is a wonderful tool. (And if you take time to read the introduction, he actually does give you a compressed version of what the design abstractions are that make op-amps so useful.... which further reinforces his description of exactly how each circuit works, and improves your ability to tweak them for your own needs.)

As a hobbyist, I presume.

Build and program some simple robot designs other people have some up with. Experiment with altering them, or recombining pieces of them. Move to more complicated designs. Then try designing your own based on what you've learned.

You'll need to learn how to program, ideally at an assembler or near-assembler level though a lot can be done in higher-level languages. You'll need to know how to access I/O ports to send commands to the robot's "muscles" and read back the results, and (if appropriate) to have it communicate with other machines. You'll need to learn enough simple electronics to build, debug, and alter (and eventually design) the robot's brain and nervous system. You'll need to learn enough simple mechanical design to build, debug, and alter (and eventually design) the robot's body.

If professionally: Take the previous paragraph and scale it up to years of focused study. And then hope you can land a job doing robotics rather than something else.

thanks for the help and i was thinking of starting at hobby level and going pro if i can grab an opertunity after college much appreciated

Type "robot" into the site's search box - there are a huge number of projects you can start with, just pick the ones that you find a challenge.
Start with nxt, it's easy to learn and helps you understand a little about programming.
