Let's Make Robots!

newbie

where to begin?

Hello I am totally new at this I am 21 in engineering (so a relatively smart person) but I want to get into this hobby.

My end goal is to make a robot like off of battle bots or something like that. I have no idea where to begin, what would you guys suggest (preferably R/C controlled)

Thanks for the help in advanced

Hello everybody, I'm Acer. I'm one of Aaronsuper1's schoolmate. I'm a bit new to robotics. So I need help. I'm making a free form arduino. I'm waiting for aaron to bootload an atmega328 for me. Gonna buy parts tomorrow. Any tips?

Driving a motor with solar cells (without a solar engine)

What I want to do is this: I have a basic bicore hooked up to a vibration motor.  He kind of flops around, but it isn't totally random.  Anyway, I was wondering how I could power him with some solar cells that I have without using a solar engine.  If that's possible, I would really like to hear some ideas.

Hello, new member here

Hi everybody,

Just registered here after browsing the site for a while. I've read a few electronics courses at university and done some basic soldering, but mostly I'm a newbie. I'm from Sweden, 25 years old, and started programming in QuickBASIC when I was 13, and moved along most of the popular languages.

Oh my am I ever excited

Good news everybody!

I'm new. My name's Cam. I've never built a robot or any electronic circuit but for some reason I'm super-confident that I'll be awesome at it.

 

I have a little bit of scripting/coding experience, I'm hoping at least some of that translates over to robot building. I'll have a heap of help at least to start off with from a friend of mine, he's never built robots either, or really done much in electronics, but he's an engineer ooh wow

My First LMR Blog... first blog ever?

So Im new here...

I have already started my first robot. And as soon as I have got it together to a some what more presentable state I will submit it as a project :)

When deciding what to create as my first robot, I looked at the beginners stuff and thought I could do that, but I still want to be diffrent which is why I am building a 3 legged walker. I'll Hopefully upload a video or two with some photos in the next few hours.

Thanks for reading and enjoy your day.

This project is my very first robot project. It has a cybot foot base with 2 DC-motors and 1 wheel in front. I use an Arduino processor as his "brain". For now my … Read more

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.

My first project, lawnmower...

Hi,

 

Im new to this forum, and new to robotics in general. The same could be said abou my knowledge about microprocessors and programming language (other than .html notepad stuff).
 I have some basic knowledge about electronics, but nothing worth braging about.

But, i have been thinking about starting on a new project soon (I'm currently in the finishing stages of a little cnc project i have for cutting out rc airplane foamies...) which i would like to start this fall, and hopefully be done with before next summer.

'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.

Howto browse LMR! (A guide to oldies)

Well folks,

A dear LMR friend recently drew my attention to his ignorance regarding the way this site works for him. This person, who shall remain anonymous, has been a member, like, for ever (in fact only 23 members joined before him). So I assumed he would know by now how threading works. And how to keep track of the latest updates.

Rearranging Best Practices

This might actually belong in the Wish-list topic, but since my text is so long I've made it a new topic.

 

It is a reoccurring problem that people post stuff on our site without respecting the "Best Practise" advises. This is simply because they dont read it, or have forgot that they've ever read it...

Help? Programming PICAXE?

I'm sorry if i sound like an idiot, but...
i have: picaxe 28 starter pack

a laptop and the programming editor for picaxe
im sorry if this is really annoying and its too similar to the start here link, but i need HELP!!! 
for some reason i cannot program the 28...

Tread Chassis Design Question

Alright, so I am new to robotics as well as this site, but here is a question I feel I have to ask.  I need to ask because it will effect a future project I want to do when I am more experienced in Robotics.

 

Alright, so the theory behind this question has entirely to do with ground clearance with a treaded chassis.  I notice that every bot with treads has very little ground clearance, and was wondering if there wasn't another way to do the chassis so you could increase the clearance and what kind of effect it would have on terrain options.

Getting Started

I want to get started, but I need help putting a decent started pack together. I know I need a board, download cable, etc, but what other toys should I start with?

 I want to be able to start off small: get a light to blink. Then move to getting several lights to blink in order or random order. Then I want to move onto attaching a motor and getting it to spin. Eventually I want to build a robot that will do all of my work, but baby steps right?

Hello I am new here :)

Hello my name is Matt I live in lancaster Ohio I am 15 and am new to electronics (AKA I have been taking apart electronics all my life but new to the putting it back together part :) and I would like to get to know all of you guys/gals.

New roboteer from Sweden

Hi guys!

I'm from Sweden (Skåne) and very close to Denmark. I consider starting building these things, because it's really awesome and robots have always fascinated me.

 

 

I would like to be at the meeting, but it came a little sudden and noone around here at home knows about it. You guys gotta keep me updated, since I may come next time ;)
