Update and finish!
Well, a Steward, waiting for a very specific acoustic command/signature at table with family.... bad idea.
"Erverybody absolutely QUIET!!!!!! .....Salz...(giggle) .... Q I E T... Salz.....", and so on!
I quickly changed the Elechous Voicerecognition with a
HC-12 SI4463 Wireless Serial Port Module 433Mhz
http://www.ebay.de/itm/HC-12-SI4463-Wireless-Serial-Port-Module-433Mhz-Replace-Bluetooth-for-Arduino-/351198720845?hash=item51c513334d:g:WmMAAOSwAHZUQIh3
I have plenty of them in action in our house - work like charm!
#0000-2222-<salz>
# command
0000 Master
2222 Slave
<payload>
This with as Raspi and "SSH Button" on my Android doues ait al.
Android/SSH-Button->wlan->Raspi->433MHZ->Steward ;-)
And fnished!

Robots can help! They should help!
Every Sunday morning at the breakfast table, again! “WHERE IS THE SALT!” – For the boiled egg!
Here it comes. With Salzfsss 0.1
An Arduino nano controls a relais controlling the power for L298N driving an old electronic infusion device motor with a string holding a peg holding a salt cellar.
There is a reed to count the rotations to define the amount of released string; a switch to prevent the system pulling the peg into the box.
And – at the moment - a simple microphone triggers the sketch to lower or raise the salt cellar.
In Version 1 voice recognition should give more specific triggers
In Version 2 the design should be more acceptable. It’s a steward robot!
Salut!

Serves Salt when you need it. Hangs over the table, waits for sound (voice command, soon) and hands me the salt cellar
This is a companion discussion topic for the original entry at https://community.robotshop.com/robots/show/salt-cellar-steward
and also, I wouldn’t test any equipment above my head with such heavy bolt on a string…
