beginner

I'll start off admitting that I'm a complete novice at robot building, so pardon me for what is probably stupid questions. I have bought an arduino with the intention of building a robot and have an idea of doing so mainly with servos, and I know that I can probably run them off the arduino without any problems helped by the arduino servo library, but can I just plug them in directly to the arduino or do I need a resistor in between or something? And question 2 How do I make my robot controllable via R/C? How do I put those circuits(?) together?

Hi LMR! I got the idea to make a little robot, with 4 wheels that van drive around. Ok, what's cool about that... so I decided to add in a camera and a wireless connection to a pc. I'm a total beginner to this BTW, but I'll figure out how to program it. The overall idea is to make a robot I can control from my pc, that transmits It's video signal to my pc so I can se where it is. My question is, which components would he suitable for my project? I was thinking about getting a wi-fi connection to work with my pc, will that work?

Okay, so I've gone out & bought my Arduino clone, had fun* with it, bought a truckload of ATMEGA 48-328's & had fun* with them and would like to now broaden my horizons a little. I'd like to see what's on the other side of the fence & give PIC chips a try. From what I can see, both have their advantages/disadvantages & can excel in some areas where the other may flounder.

Thanks a lot for the support you people showed last time. I want to make a circuit which has 2 LEDs and a normal on/off switch (at least) and other components as required. The circuit should function like this- When i turn the switch on for the 1st time, LED 1 glows but LED 2 remains switched off. When i turn the switch off for the 1st time, both LED 1 and 2 remain off. When i turn the switch on for the 2nd time, LED 2 glows but LED 1 remains switched off. When i turn the switch off for the 2nd time, both LED 1 and 2 remain off. Please provide me with a circuit diagarm for the same and

I am setting up a basic electronics/robotics lab at my school. I have been trying to figure out what a good soldering iron would be for the classroom or if one of the kits available, which contain other useful tools, are viable. This is a class/club where both the students and teacher (me) are relatively inexperienced. We bought some cheap soldering irons last year but they are already useless and I don't want to make the same mistake twice. So, I guess I'm looking for warnings as much as recommendations.

Hi, I'm beginner of this world. Wanna get some help. Where i can get the materials if don't have any credit card ? Or maybe there's a guide how to build it ? Thanks

Hello everyone!

this is my first post so im pretty excited haha.

i want to know how to create something so i can shoot high speed photography.

an example of what i would like to do is of a water droplet hitting a bowl of water and snapping a picture when the "crown" (part of the water which gets drawn up from the result of disrupting the water bowl".

i was thinking about a laser activated "flash" which fires the flash of the camera after the beam is broken, but it should have a delay so i can fine tune it and get the perfect image.

I am looking to upgrade my first robot which is built from the LMR Starter Bundle. I to start out I would like to upgrade to 4 motors. Currently I only see the A & B pins for motor control. The motors do not need to be independently controled, I only need to be able to control 2 at a time. Is this doable?

Also, I eventually want to upgrade to bigger motors, would it be easier instead using 4 triacs or relays?

Thanks,

This is a very simple question and I am only asking because it is fundamental to my first robot (and I don't have the money to get this bit wrong).

 So I'm a complete beginner at this. I know ohm's law and generally what components do, but I've never tried to put anything together yet.

'Going to build a YDM'

Bit ambitious as a first project, but I have 'some' background in programing.

Right now I am a student at University of Idaho. I am taking C++ and attend the ACM meetings. ACM is a group on campus that does programing challenges and is now dabling in robotics. They recently got an Arduino board, and it is my understanding that it uses C++.

This will be my first robot, except for a semester in high school where I programed a robot to navigate a maze using only a sequence of commands.

Hello, I am new to this site so I hope you won’t mind if I ask a few questions that I am sure are going to sound quite amateurish to most of you. 

I am an American living in Berlin working on a collaboration between two art research institutes here.  I have been given the task of putting together a proposal for a dynamic moving display. That will be featured next year as part of a conference on kinesthesia. 

Hi all,

I am very new to building robots and don't have much knowledge of electronics, apart from the basics many years ago at school.

However, I got an arduino at the weekend and have started doing experiments with it. I've just managed to take apart a cheap RC toy car and get the arduino to make it go backwards and forwards via a L293D motor driver and a very basic program. There are two motors in the car - the other one is a DC one attached to rack and pinion steering - I've not connected this to the other side of the L239D though yet.

hey,

So i"m an advanced desktop/web apps programmer and MCTS WinDev so far, and I've done it all completely on my own.

 After a few weeks of research now I've realized I might be able to build a simple robot, I've already chosen my shop and products, my ideas are usually quite ambitious.

I am an absolute beginner... i have very little experience in electronics, very little experience in mechanics... but i am an expert programmer...  my question is: what do you recommend for a beginner wanting to get into robotics?  I am thinking I might want to get a roboduino board but I see here a lot of people are using picaxe. 

The advantages of something like the roboduino is that the board is pretty self contained and wouldn't need a seperate board to drive the servos...

Any suggestions as to what type of micro-controller might be best to start with?

Hello

Im envisaging on building my first robot, so would greatly appreciate any advice.

About me > I've some basic programming skills through GW-Basic and QuickBASIC which i learnt nearly 10yrs back. I suck at C programming, and am not well versed with microcontrollers/electronics, although im sure i can learn (maybe not C!!). Mechanically, im sure i can conjure up something fairly decent, if not pathetic!
