picky motors?

 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!

'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.

Large Solenoid Actuator driven Display

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. 

Battery Question

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.

advice fr desktop programmers first robot

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.

This robot is navigates by (avoiding) wall and cliff. It moves around the floor, vacuuming it.

As my first microcontroller robot, I have made a two-wheeled robot with bumper switches and edge-detction (because I have death-causing cliffs in my house). The … Read more

Best for Beginners?

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?

Beginner robot..suggestions please!! (Axon and VEX for the bot)

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!

Arduino servo twitching

robologist's picture

Servo twitching. I know, simple stuff, but it's interesting to play with on new hardware. Another Arduino example "sketch" (they got a number of these) called Sweep simply moves a servo through a set range, back and forth. Just looking at the sketch (listed at bottom) this timeshows a servo controlsignla connected to pin 9. They recommend using the boards 5 volts to power the servo, which is coming from the USB connection. If I'd had a bigger servo, or was under load, it might be appraoching the 500 mA USB limit (or is it more now?).

Earlier today got a FedEx delivery of a MakerShed order placed last week. Toys!

 One particular toy was a new Arduino Duemilanove. Had to see what made the Arduino popular.

'Where to start' suggestions

Hi All,

I have just joined this forum so this is my first post!

I really want to start building my own robot but I don't know where to start?  I am a C# programmer so have lots of experience of coding and I have had a look around and seen that the Picaxe chips are programable.

My question is - where should I start?  Is there a particular place I should start bearing in mind my C# knowledge?  Are there any kits out there that I can use C# with?

Thanks in advance for any advice you may have for me!

James.

Yay! n00b :)

Yay! I'm really excited to have finally joined this site. I've been reading for the past week and LMR has really helped out sort the kinks in my design.

I'm an EE major, so I lourve robots. For my career, I reallllly want to work on making robotic prosthetics for the disabled.

Suggestions for a Book on Circuit Design

jklug80's picture

I have a fairly strong background in code development, but I would like to build a stronger knowledge in curcuit design. I can read a datasheet and learn how to hook up a certain component, but when it comes to using a specific component for a use other than it is designed for I lack the knowledge to know when to use a capacitor, flyback diodes, etc.

i need help on building my first robot

im a BS Information Technology student from the Philippines.. currently im trying to find a away to build my first robot (its a project.. i gotta make one) without first hand knowledge.. im having problems on finding a shop that has the materials i need.. (we dont have radioshack here).. so.. if anybody here is in the philippines.. i need your help.. so bad..

I am new to Robot. Compatiblity Question???


1. Which kind of motors are compatible with PICAXE? I've read in a book that PICAXE doesn't compatible with DC motors , but Servo motors. There are many kinds of servo motors and how to choose a correct one?

2. Which kind of infrared sensors are compatible with PICAXE?
