Arduino vs Picaxe

Should I go for Arduino or Picaxe for my next robot?

(EDIT: Please note that this is a very old post, things have changed :)

Next generation LMR: Submitting robots

Del Rudolph and I are designing the Next generation LMR :)

Now, I can promise you that we can not implement even half of the ideas that our thousands of creative and talented members might have :)

BUT! I would like to ask if there is any fields that you would like added when submitting a new robot project. Or more like; Are there ways to FIND robots that you wuld like? Because if we implement new fields, like "Does it have sound", it should be because you'd like (or think others would like) to look for "robots with sound".

This is just a very simple way of getting a sense of distance
This may be extremely simple, but then again, some one out there might get inspired by this thing that I just "found", so I decided to share :) Actually I started … Read more

How to safely connect more lipos

Connecting Arduino to Mac and PC, the easy way?

While working on an Arduino-start-here tutorial, I am trying to find the most "fail proof" way to hook up an Arduino.

Now, if I could decide what OS and connection everyone had, it would be easy as this:

* Install Ubuntu 10.10 OS on your PC
* Install The Arduino IDE (and write your program)
* Insert an USB-FTDI cable from conputer to Arduino board
* Select the serial port

- And done, you can now press the "upload"-icon, your program will compile and upload.

The above is so far the easiest I have found.

You can detect footsteps, and the world below!
I just discovered geophones by watching the video. Check it out, Geophones, it's the latest. You can make one by hanging a magnet in a rubber band, and let it … Read more

Does disabled persons pave way for robots?

Please note: English is my second language, I may involuntarily make fun of people without legs and or ears etc. This is not the intention, and I am sorry if it happens!

Because of this: http://letsmakerobots.com/node/24014#comment-58207

I just got to think: There are many places where the installations for disabled persons may have paved way for robots to do stuff.


Thinking about it, the ultimate goal must be a robot that can not only build new robots, but the robots should also be able to submit themselves on LMR! This … Read more
