I also do consulting for robotics , mechatronics, and special effects projects/products. Check out my website - narobo.com for more details.
Ever wanted a butler robot that talks to you , follows you around , and even pours you drinks? Read this instructable to learn how to build your own voice controlled butler robot which has many cool features.
This tutorial will show you how to make the butler robot , but any improvements that I add after this tutorial is finished will not be edited into this tutorial, but rather it will appear on my robotics blog : eRobots.BlogSpot.com . eRobots.BlogSpot.com My blog has a lot of cool robotics and electronics stuff, so check it out!
Please note that this tutorial can be modified to each person's needs and you do not have the follow the exact dimensions that I wrote. To make it easier for users I did write the dimensions that I used if they wanted a reference point.
I built my first version of my butler robot in 2007 and in June 2008 I began to make a newer version. The older version can be seen here:

The Functions of The Butler Robot:
1. Voice Commands for weather, time, and temperature
2. Pour a drink bottle into a cup
3. Manual control with a joystick
4. Cool soda cans in a mini fridge
5. Face recognition and greet people by their names
6. Follow a person wearing a certain color shirt
7. Avoid obstacles
8. Automatically dock to a charger
9. Sweep the floor
10. Wireless control over the internet
11. Wireless Remote Control from iPod Touch or SmartPhone
PLEASE VOTE FOR ME
I WORKED VERY HARD TO MAKE THIS TUTORIAL VERY CLEAR AND EASY TO FOLLOW.
Someone told me that this looks like dalek from Doctor Who. Holy cow it does and I didn't even hear about Dalek or even Doctor Who until this morning!
MY PROMISE: If I win this contest and win a ticket to RoboGames, I will make a sleeker , cooler version of my butler robot ( equipped with tri-tracks, CNC body, better robot arm) in 2009. I will enter that butler robot in RoboGames 2009 AND I will document that revised version even more than I documented this robot! That's gonna be a very very detailed tutorial!
So please vote for me !!!

Also I want you all to know that around 50% of all the parts I had from beforehand in my workshop so it only costed me like 50% of the total price listed here. You too probably have a bunch of the above parts lying around your house or perhaps you have friends who would be willing to donate parts, just use your resources and you could make this thing much cheaper than it is now.
Total Bill: $420.14 + laptop of choice

I realize I am a bit of a late-comer (If 3 years is considered late), and I recently discovered this project while browsing robotic videos on YouTube. I have to say, this project is MARVELOUS! Fabulously explained, and a very innovative idea! A truly amazing project.
www.jameco.com
You can probably still find them either online or at a science/discovery store. As I remember, I got it as a xmas gift and it only cost around thirty bucks or so back in the 90s.

Thank you for your cooperation.
By god I love this site. Found it today at work and I've been on it pretty much all day since getting home. I hope to start construction on this and/or the Doctor Who K9 unit in the next year. It'll be my first venture into robotics, but I'm good at following directions and not afraid of failure. Thanks for building this and thanks for putting up this instructable!
Please feel free to hit me up with any advice as I'm the newest of noobs to such things.
my first project will probably be a sonic screwdriver.
:)
-swiveling head for use with remote control.
-speed settings for movement.
-slower pouring of beverage so it doesn't spill.
This is by far one of the coolest instructables. Great work!
and i dont really see it cleaning and such in action.
and plz can you make a modified instructiable without mini fridge and with 2 robot arms and no arm for beverage.
and maybe 4 clawed arm so it can really interact with more things and then i can help you.
(i am not technical with hardware you know)
but i am with software.
so i can make it like search for cola and really fill your glass with grabbing the bottle and more cleaning and assisting.
the minifridge could be an automated storage for the butler robot (chives)
so when he needs something he can open the door.
and then grab something out (that might be hard)
but can you plz i mean plzzz
provide an slight modified instruction on how to make a slighly more advanced arm plzzzzzzzz
then i swear i would help you with all i can.
(i have a lot of free time =D )
and i understand why you dont want to do a tutorial style one XD :P
its so much to type and discribe.
but well if you have time you could make a small explanation (not a full new tutorial)
but an add on tutorial witch is made in a new instrutables tutorial where you just say the steps number and just say what you could do instead.
because if you modify or improve the arms of the robot butler, then the value and the interactivity and usabilaty and (LOL) it can peform more help tasks.
if you could only add that than i would be happy.
(and well i ment a very small improvement.
just an extra servo in the arm witch could bend the arm so it can grab things from different heights easier.
i would recommend 2 servos on the arm of the robot.
(close to each other)
one for up and down movement.
and one for right and left.
then i could help with programming.
but the only program if i would try this is the controll hardware.
where the servo should be attached to and how to communicate to it.
well strapping some wires to the serve and making the inside the tube of the arm or against it isnt that hard though XD
well i would like to participate help or maybe even suggest idea's
since i got alot of them =)
and i could help on the software if arm improvement has been done.
so it can really pour drinks from the table.
and just take a broom or vacuumcleaner and use it to clean :D
and just control anything you want.
well and with hardware. i can help you improve speech recognition (i am a vista expert :D )
(microsoft really likes my help and beta testing ;)
http://narobo.com/articles/Sketchup.html
and small robots
using the small ones as an "escort" or something like that
also, can u possibly make this like a self moving workstation with printer..., cuz i kinda need something like that? ..
thnks

I spoke to moderators and the admins. They suggested I make this page:

get ready for the code and videos guys , that will be up this weekend.
Code maybe even tonite , it just takes time to write some documentation clearly describing my code.
Enjoy
and thanks for the vote!
thanks for the feedback as well

I'm typing up the bill of materials as I speak .
i'll PM you when I am done
@=SMART=
There will be some more steps ,lol , explaining my code
