hi there everyone :)
i want to join the robots community but i have no idea about robots at all
i'm a .NET programmer c# , c...
i hope you give me some tips to follow in order to make a robot at least a beginners robot
and thank you so much :)
It off course depends on
It off course depends on where you wanna go, but personally I’d recommend the following. At least this is what I wish someone had told me when I first began fiddling…
Get an Arduino Nano clone, a small breadboard, some jumper wires and some peripherals to play around with… say for example some LEDs, a potentiometer, some servos, a couple of small DC motors, an H-bridge chip (for the DC motors) and an ultrasound range finder. All of this can be had extremely cheap off ebay (for example). The rest can be improvised along the way.
The Nano plugs right into the breadboard, can be connected to your USB port and then you can start playing with the peripherals one by one (lots of examples/tutorials on the Arduino website and elsewhere).
Once you’re comfortable with all of this it’s time to put it all together. A simple “start here” type robot typically has 2 DC motors with wheels attached and a range finder mounted on a servo. Here you can off course buy some stuff (e.g. wheels) or you can just get creative and steal some wheels off your nephews toy truck for instance (haha… no please don’t do THAT :).
For putting it all together I’d recommend double sided tape (it’s stronger that one would think) for the parts you wanna reuse, and instant glue for the parts you don’t care about reusing. Hot glue is also very popular on these pages.
Then off course there is the issue off batteries. I wont go too much into that other than mentioning that an easy and common solution with smaller robots seems to be using 4 AA batteries to power the motors/servos and a 9V battery to power the Arduino.
PS: I’d also recommend reading the tutorial OddBot linked to 
My first suggestion is to
My first suggestion is to get a small computer. This could be an Arduino, or a Raspberry Pi, or something similar, a breadboard, and a small collection of parts.
You can find tutorials on the web.
With the Arduino you need an IDE on a PC, Mac, or Linux Box. This IDE is free and is available at Arduino.cc.
The Arduino uses a C-like language, and the RasPi can be programmed in either C or c++.
Once you’ve gotten these together, try the basic experiments such as turning an LED on/off, and using an analog i put and output.
Then feel free to try the hello world robot.
After that, the next steps are up to you. Build a bigger or smaller robot, both are a challenge in a new direction. Above all, try to have fun. Robotics can lead to surprising places, for example, I will be experimenting with marble runs eventually and 3d printing as soon as I get a computer together.
Please try to have fun!
wow i didn’t expect all that
wow i didn’t expect all that … thank you so much , but i’m like so beginner i didn’t even understand some of your words (like someone who doesn’t know a word in chinese and suddenly u post him there)
i think first thing i have to start with is programming cuz i don’t have the needed materials here (i live in a small city in Morocco)
so if i finished the code alright… i’ll try to get materials & my question here is how to transfert code from computer to the robot
will it need some analog converters or something?
i saw most of your topics and it’s really inspiring
i really thank you so much folks :)
Hi again Y-art (or rather
Hi again Y-art (or rather Aniss).
After talking to you in the shout box you made me understand that you are indeed on a budget. Therefore I think the start up approach I recommended is even more valid.
Here are some links to ebay so you can see that you really don’t have to pay a lot to get started.

Just some options (to be continued)…
EDIT: I’m not entirely sure that these particular DC motors are geared for a robot. I’ll post some alternatives in a bit… Also I would ask someone else about the batteries, which I’m not the right person to give advice about 
I actually ordered those DC
I actually ordered those DC motors, so I can verify when they arrive
any idea about the speech recognition !!
hello guys ^_^
hi Anis , you know i was afk cause of ‘Eid’ thanks again & i’ll definitely buy some of that if not all 
i think i need a speech controle to my project
i found Easy VR and it looks so satisfying , and bitvoicer… what other speech recog controllers do you guys recommand?
