Learning to use WiFly RN-XV module, any advice?

Recently I have started trying to add WiFi to my robots. The WiFly modules seem like a good choice. Reasonably priced and they fit in an XBee socket so that I can easily swap the hardware between Xbee and WiFly. For this reason I added an Xbee / WiFly socket on the ComMotion shield. Unfortunately I know nothing about networking so I have a steep learning curve ahead.

Spider controller

The DAGU Red back Spider controller is an Arduino Mega (1280) compatible controller that is especially designed for driving a large number of servos. All 70 I/O pins are terminated in servo compatible 3pin male headers as well as the standard female header and the power supply is a switchmode power supply delivering 5V @ 3A from an input voltage of 7V - 32V.

Fish Heads! Why it hurts when everyone talks about burgers, steak and pizza!

To begin with, this forum is not intended to insult Chinese cooking. It just shows one of the many differences between east and west.

How to use the serial port flow control to reset an Arduino from a PC or tablet? (Solved!)

I want to connect an Arduino to a tablet and have an app on the tablet reset the Arduino if required. The robot I am designing has multiple Arduinos and sensors all linked via I2C. One of the Arduinos (the master) connects to a tablet via the USB and passes commands from the tablet to the various slave Arduinos.

Beware of these recent phishing scams

This is nothing to do with robots but I have had 2 scams in 2 days so I thought I'd warn you. Recently there have been some high profile security leaks and it seems there are some arseholes trying to take advantage of it.


The first scam claimed to be a shipping confirmation from Amazon with an attached zip file. Since I never order from amazon and the email address is bogus, actually sent from "newskmle@idriveyouupawall.com" I knew it was a scam and automatically deleted it.


Help to convert a blank ATmega328 into a speech synthesizer chip for under $5

Some time ago when I was looking at the cost of speakjet and other hardware speech systems I remembers that back in the 80's there was a program call S.A.M. (software automated mouth) that ran on my Atari XL. It was also available for the C64, Apple and possibly some other systems.

Topics for Lumi's next photoshoot

Occasionally Lumi does a photo shoot with some very pretty girls and is good enough to share with us. I would like to get suggestions for Lumi's next photo shoot. There is no guarantee he can or will do it but we can still ask.

Max's gifs often make me wish Lumi could do a photoshoot like that. Hopefully Max can post a few here for inspiration. This was my inspiration for this post:

Please post suggestions of what you would like to see as a theme for Lumi's next photo shoot.

T'REX robot controller


The T'REX robot controller makes controlling robots easy!

The Arduino compatible controller comes pre-programmed with sample code that lets you control it with a supplied Android app, Radio Control or with an external controller via I²C.


Updated instruction manual for Mini Driver

The Mini Driver was released by DAGU some time ago. It is essentially our Magician controller in SMD format. Unfortunately the engineer who designed it does not have very good English so I was asked to re-write the manual. You can view/download the manual from here: https://drive.google.com/file/d/0B__O096vyVYqczRjX1k5LTRkcjA/edit?usp=sharing

Updated assembly manual for Service Droid owners

Another minor update. I've now included the instructions for adding the sensor wire to the servos. Note that this will void the servo warantee as we cannot guarantee the quality of your work. The instructions were included because if you do want to modify your servos you should do it before assembly begins.
