What microcontroller should i use?

Am planning on building a robot that  would have the abilitty to navigate , avoid obstacles and collect some items.

What chip should i use?

Whats the difference between pic and picAxE?

 

thanks in advance :) 

Ever feel like your being watched?

I was checking some samples to go to Germany and had a strange feeling that I was being watched.

Maybe this job is getting to me. (all the eyes....)

SSS - Servo Suspension System

This is my first experiment with the MakerBot. I am totally thrilled with this machine!!!

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results as soon as possible (still waiting to have my lab back).


I would like to know everyone's opinion on this  :)

I built this from a kit.  Preprogrammed IC, and simple IR system.  Great way to learn how to solder onto a circuit board.  Since completing robot, I've detail … Read more

Code Repository!

Can we get everyone who has got their code to successfully run to post their files here? Ive been looking all over the site for a central area for code, and I cannot find one. If there is one, point me in that direction, if not, lets all start posting here!

Try not to paste lines of code here, lets keep it clean. uploaded files only please!

Format:

Name of code,

What do you guys think?

real shops in London

Does anybody know of any interesting robot parts shop in London town, UK?

I'm on my way there tomorrow on a business trip, and have time to kill.

I'd love to go into a shop and touch and feel stuff before I buy...

Where are the attachments???

Here is my question for the Admins: Where are the attachments on my robot page? Why are they only visible when you log in?

Scoots Plan

Well im starting to make a robot named Scoots and it will be in like a bowl with LED Eyes and will be like a beetle bot. Since im a scavenger and i hate buying stuff above 10/20 $ i will make it only from parts in my house or cheap junk i bought.

Swarm AI beginnings (XMOS Competition)

Last Update: 13/10/09 XK1 first look pictures.

My XK1 arrived this morning via Japan post. Being so close to Hong Kong I might be the first :P But they were sent out on the 9th so those people waiting on one should go check your post box!

Vacuum forming plastic parts.

Heres a few photos of my home made plastic vacuum former and its maiden test. If you don`t know what vacuum forming is check here, and youtube.

Essentially a sheet of heated plastic is placed over some kind of mould which then has the air sucked out from underneath it. The soft plastic schloops to the shape of the mould and when it cools you have yourself a robot part. It really does sound like schloop if you`re wondering.

Line Follower using Atmega8

Hi all, I am new here and about to make a debut in robotics with a simple line follower robot.

I have chose AVR ATmega8 as my microcontroller because I found out that we can chose which pins we want as input and which ones as output. So this seems pretty cool for a microcontroller. Also i figured out that it is cheaply available here.

General help Needed - Desiging next robot

Hi. I am making a robot that runs like a car but has a camera on it and runs over wifi. Sort of an city explorer bot. Does anyone have any suggestions on the parts I need (based on my framework), or any other parts? Or any other recommendations whatsoever? any help isgreatly apprieciated.

Routerbot (Without hacking the router)

I am intending to build a routerbot. This is my design idea. This is my first major robot so please comment and suggest if even the slightest urge arises.

I will call the robot flat friday.

Design brief so far...

What I want the chassis to look like (minus the gun)

Entry For Oddbots Robot Video Competition

Hi all, it's 2:44 am (yawn), and here is my video.

 

I spent ages trying to work out the music for it only to find out just before uploading it

that Youtube will probably mute it :(

 

Oh well. if it happens i'll try another service.

anyway do enjoy. 

 

Low RPM Motor With High Torque Needed

I need a motor that has a lot of torque but the shaft looks like this:

 

GEARS.jpg

I CANT FIND ONE!!  I need it to be cheap though... If anyone knows anything at all, please let me know.  Thanks!

P.S. Even if I have to slightly modify the motor, that's ok for me too!

Suggestions on choosing motor

Hi

Im considering on buying the following motor for my project.

Quick specs : 12V, 150 RPM, 195 oz-in torque, 67:1 ratio

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!

Dual 18F4620 board with supporting 18F2525 for display

Right now I am working on my master-slave-slave board that will suit my needs for a long time. It has a master 4620, that communicates to another 4620 for processor assistance.

 4620 MASTER: Spaces for 5 servos, rs232, I2C, sn754410 motor controller, 8 ADC channels, 2x5 header so it is expandable into another board.

4620 SLAVE: Setting switches, proximity IR sensors (8 for complete sensing), speaker, encoders (rear and front for a car drive bot, left and right for 2 wheel operation), 38khz IR led driver, bumper switches and spaces for 6 servos I2C.

Robotic Crane using PIC16f or 8051

hey! i'm planning to make a robotic crane.and i reallly need help.

the basic idea is to build a robot WITH PIC16F877A (OR 8051) which carries magnetic loads(it has other auxilliary functions as well)

what is wrong?! ..and what can i do!?

okay..         so i just finished my new robot(8 servo quadropod)and started makeing a test program.   when the test program was done i downloaded it to the picaxe and it worked! then i started to try out use the srf05 to see if it was plugged in the right way! so i made another program and tryed it and that worked too!

my robot is using the picaxe18 power board from sparkfun.com. he turns both ways and decides which way is better to go and goes that way   here is my … Read more
