The robots liked it so much last year, I've taken an extended group back to Barley (Pendleside, Lancashire) May Bank Holiday Model Engineering Show again this year.
These two enhanced Robie SR's are showing off their SP0256 "Narrator" speech chips:-

These Robies can operate in "Autonomous" mode or by 2.4Ghz radio control. As well as ultrasound and electronic compasses they have built-in "RoboCams".
Their brains are 3 Arduino UNOs linked by I2C. The master processor UNO holds command sequences, and also reads output from the 2.4GHz RX modules, ultrasound units and compass. Slave 1 works the 7 segment display pairs (ultrasound feedback) with a 6-bit BCD data bus to each pair.
Slave 2 holds the speech dictionary (words constructed from allophone sound fragments) and drives the Mike Hawkins speech processor card.
Some of my robots went on a rare outing this weekend to guest/exhibit at Barley (Pendleside) Lancashire May Bank Holiday model engineering show.
Enhanced Omnibot shows off the new grippers on his power arms. His brain is a stack of 5 UNOs - 1 master and 4 slaves which control his servos, his synthesized voice (SPO256 "Narrator" using allophones), and his front panel matrix display.
“Claremont Road” has five Arduino UNO microcontrollers which control train movements along with PWM (servo adapted) points/turnouts, and signals according to pre-written programs or “sketches”. This is a completely different concept from DCC.
The master co-ordinating UNO gets feedback from the track through 14 enbedded infra-red proximity detectors,
Slaves 1-3 are UNO “train drivers”,
Slave 4 handles the display and lights. The orange display shows the current mode and commands being passed between the UNOs via a short-wire protocol known as I2C.
Arduino UNO provides 6 bit data and the necessary handshaking logic for a vintage Burroughs SSD0132-0040 Self-Scan gas plasma display c.1976. The row of LED blinky lights, aside from being mesmerizing, shows the state of the interface logic with delays built into the sketch to help diagnostics (on my first attempt I had the 6 data bits in reverse order).
The wire shrouded in red heatshrink tube on tag 10 of the lower connector is the +250 volt DC supply required by the Self-Scan

The row of LED blinky lights, aside from being mesmerizing, shows the state of the interface logic with delays built into the sketch to help diagnostics (on my first attempt I had the 6 data bits in reverse order). This pic shows clearly the dot matrix pattern making up each character.
Arduino UNO does PWM (pulse width modulation) – 16mm scale.
This test board has a UNO configured to provide 6 PWM servo outputs as a microcontroller for points (turnouts) and/or signals on my 16mm scale narrow gauge exhibit. Two vero strip boards incorporate the required crossovers to provide Futaba/Hitec/etc format servo pinouts on the UNO’s digital output sockets.
Each of the UNO’s analogue inputs is held at intermediate potential by a pair of 1 Kohm resistors. The remote commander has a 20 foot wander lead and its four momentary push buttons short out one or other 1 Kohm resistor to take the analogue input to LOW or HIGH potential as a tri-state switch. The UNO picks up the change in potential and moves the corresponding servo through the number of degrees pre-programmed in the sketch, via the selected PWM output.
This basic setup will enable the option of automated signal and point control on the 16mm scale exhibition layout by linking the UNO's analogue inputs to other sensors.

Robot exhibit - I built these controllers (transmitters) using Arduino UNOs for my enhanced Robie SR's when working in 2.4GHz wireless mode. The arcade style joysticks control movement whilst the numeric pads allow execution of stored command lists including speech.
The * (star) key puts the enhanced Robie into wireless control mode, and the # (hash) key puts the Robie into autonomous mode.
Still a work in progress but the hardware and electronics are complete. All that remains is to finish the programming.
My intention is to have these robot arms re-enact some of the "Great Brilliancy Prize" Games of the chess masters.
A central master UNO stores the command list for the moves, and feeds these alternately to two slave UNOs which drive the servos.
I rebuilt the shoulders and elbows to fit dual contra-rotating servos. A problem I didn't anticipate was that the servo travel from 0 deg. to 180 deg. is not exactly linear. I had to build in a numeric adjustment of up to 5 deg. in the "write" commands, to keep the partner servos as close as possible in synchronisation. The master UNO can also issue a command to park and cut the power on the currently inactive arm, to minimise overheating of the servos in that arm.

Your eyes only! This photo will self-destruct if you forward it on.
In our house we have 5 kids. Someone is always leaving the refrigerator door open. The excuse "I didn't notice that is was still open".
We are working on a new project with the Arduino for a Refrigerator Alert System. There will be an LDR inside the fridge that when the door is opened and the light comes on it will activate the system. If the door is not shut all the way, the 8x8 LED matrix will scroll text across that says "Door is Open. Please Close Door".
We also want to try and use a .wav file that plays the same message. An alternative would be to just beep an annoying sound.
You can see the concept working at:

I am currently working on a project with a 5 watts; 18" L x 12-1/2" W x 1" H solar panel. Rather than use up one of my Arduino boards for this project, I decided to put one together following Tom Igoe's ITP Physical Computing site itp.nyu.edu/physcomp/Tutorials/ArduinoBreadboard
Repel is an interactive wearable art that simulate the situation when our personal space is being invaded. This artwork tries to leverage on the current crowded environment that we are used to and hope to raise awareness among people.
Repel is an arduino and electronic project, it made used of infrared sensor to trigger all the electronic component that user are wearing, such as DC motor, Servo motor, LED animation and etc.
On the user’s left shoulder, Repel will emits a red laser beam that rotates 360 degree to create a user personal zone. In the event when there are strangers invaded the zone, it will trigger the infrared sensor that are located on the user’s chest. The sensor will then trigger a series of actions. For example, the laser will rotate, the LED that signifies the heartbeat will blink and the button will spin. The closer the stranger is to the user, the faster the rotating speed will be.
For overall, Repel is trying to project a person’s uncomfortable feeling when there is someone close to them by using some electronic components. Such as the laser represents restriction, the red LED represents heartbeat and the button represents the user’s emotion.

-Arduino Uno board
-Three Dc Motor
