Hockey MANOI + Wii Nunchuck

Posted by Erin, the RobotGrrl on Thursday, November 20th, 2008

Today (Thursday) I got my MANOI working with my Wii nunchuck!

It was super easy since I already had the configuration ready because of my other robot.

Here are some pictures:

The SSC-32 is barely visible anymore!

The big transformer powers the battery to give it 12-13V (constantly). The small transformer is for the Arduino, cause I couldn’t find a 9V battery

MANOI’s back- the battery and Arduino are attached to tape using velcro

The way it works is the Wii nunchuck has an i2dc interface with the Wave Shield, which is on the Arduino. Using the Nunchuck library, you know what button is being pressed and values of the accelerometer.

I already made functions to determine if the nunchuck is tilted home, left/right or up/down. Soooo, I just added the “skating” functions to that, and the condition that the C button has to be pressed. There’s more control this way.

To shoot, it’s just the Z button.

The most surprising part of all of this was when I realized that MANOI “skates” better when I added all the stuff to his back. I guess it adjusted the center of gravity just right!

There’s a video here:

I still have some more stuff to do… like add a few more motions and sound.

Friday Night Robotics

Posted by Erin, the RobotGrrl on Saturday, November 8th, 2008

Yay!! Tonight I worked on my new/old robot… It’s the robot with the chassis of the Stanley robot that I started making at Stanford in the summer. It has a gerabox to power two motors for front wheel drive, plus there’s a servo to “steer” the gearbox.

The cool part is that I use a Wii nunchuck to control the robot Tonight I coded in which way is which- tilted to the left/front/back/right. The tilt to the back doesn’t work very often, so I have to fix it
By this point, you’re probably wondering where the pictures are I can’t upload photos with this version of wordpress (and I’m too sleepy to ftp them right now), but I’ll add them in tomorrow as I’m changing my blog to Wordpress 2.7 tomorrow, with a new theme I really really really like the new theme. It’s going to be awesome!

All Coding Ahead

Posted by Erin, the RobotGrrl on Saturday, September 27th, 2008

Woohoo! I fixed my soldering iron - it’s FANTABULOUS now! All I did was file it with an Xacto, and sanded it a bit. Now I can finally tin the tip (before I couldn’t) It’s amazing!

My two WiiChuck adapters are finished - I tried to make it work this afternoon, but for some reason the WiiChuck header file by Tom Igoe isn’t working!!! I’m confused… maybe it’s because I’m using Arduino 0012. I’ll be playing around with it more tonight.
The WaveShield is all soldered up I’m thinking about which song I should put on my SD card to test it out… hmmm

There’s so many fun things to do eeeeee all of them are now at the coding stage yay!

Fun Weekend Ahead

Posted by Erin, the RobotGrrl on Friday, September 26th, 2008

This weekend is going to be pretty fun for me
I have soooo many things to play with, it’s going to be wickedly hyper awesome!

I went to the RobotShop and got my Lynxmotion SSC-32, Soldering station, and some female jumper wires, and a force sensing resistor!
The SSC-32 is awesome! I tried it out the other day, and my MANOI is ALIVE! I made it move its head
The only thing though is that I’ll have to power all the servos externally - which is okay now as I got a 12V DC transformer to plug into the breadboard
The soldering iron is horrible I was (and still am) trying to solder the Wave Shield, but the solder won’t stick to the iron So far it has taken me 3 hours (and counting) just to solder in the resistors. The iron doesn’t melt the solder, and the flux is GOOEY! It’s disgusting! I’m even trying lead solder (this stuff SUCKS) and it won’t work… going to try to sand the tip tomorrow, and see if it works better.

The old soldering iron literally exploded… so it’s in the garbage now.

I also bought a nintendo wii nunchuck (the accelerometer thing) to go with my WiiNunchuck Arduino adapters. I’ll be using it to control MANOI (and of course, many Processing programs)

I was playing around with the Fourier transform again today… and I somehow made it to morph time. It’s really freaky! I was recording sound, when my watch beeped. When I played back the sound (after the FFT alg) it was morphed… in a totally weird and unexplainable way XD kind of sped up, but also kinda moshed together…

This entire week I’ve been studying for the SAT. This pretty much involves me trying to sit in one place, focus on one thing, and not fall asleep/daydream for 4 ENTIRE HOURS! I just can’t stay focused that long… I make so many sleepy mistakes … I have absolutely no idea what to do. The real SAT is on October 4th (in 1 week) I’m not really in a panic as the test is so trivial and boring … I just can’t focus on one thing for more than 45 minutes! My brain is always in hyperdrive mode thinking about what ifs and whys… “Why exactly do they think this test evaluates your reasoning abilities” “What if they made this test interactive, like a game, on a computer?”

I’ve been asking what if and why a lot the past week… here’s some of the questions I can remember

What if time wasn’t measured in anything… but was just a continuous flow like a river
Why do we have to measure time?
Why do we always use graphs in two dimension? I don’t care about a squiggle function on a line… why can’t everything be graphed in 3 dimensions?
Why do we always round decimal points when it’s obvious it gives us inaccurate answers?
Why is the tinfoil on my lamp making high pitched noises like vibrations? Is it because of the heat… or did I just discover something I should look into further about light?
What if light had mass?
Why don’t we know what’s in/through a black hole?
What if we could make our own net of space and see how everything interacts with anything?
Why didn’t they put more corrector magnets into the LHC?
What if the computer isn’t monitoring enough information to really see what the Higgs is like?
What happens if they’re smashing the wrong particles together?
Why can’t they just model it on a computer?
Why is the LHC in a circle?
What would happen if it was in a spiral?
Why are my desks always messy?
What will happen when robots will become pets?
Why are people so judgemental about robots?
Why are robots stereotyped to be wirey and ugly?
What if the answer to better AI systems would be to create an “AI Internet” with many algs, and an API, to create a general AI?
What if cancer can be eliminated with the use of dandelions?
What if robots could code themselves and make better versions of their algorithms?
Why is random not random?
What if there were many robots in one square, and they were given random coordinates to navigate to and from? Would it be classified as swarm robots as eventually they will all converge?
What if I made a parrot robot that could read twitter feeds out loud, in a parrot voice?

So yeah… that’s pretty much the way I think all the time… I hardly can focus on one thing, ever!

Weeeee I can’t wait to get MANOI moving and waving this weekend!

Wii Nunchuck Controlled Robot

Posted by Erin, the RobotGrrl on Saturday, December 22nd, 2007

This is what the article says:

I connected a Wii Nunchuck controller to an Arduino, which takes the data from the controller’s I2C data bus, decodes it, and send the data to the robot with a radio transmitter. Charlie uses a radio receiver to get the data, and it will control the drive servo system and the pan tilt servo system using the data. The Nunchuck has a 3 axis accelerometer, a joystick, and 2 buttons, it is absolutely awesome to use with a RC robot like this.

~~~

I have a great idea… I’ll save up my allowance and buy another Arduino and buy a nunchuck wii controller, then put it into my MANOI, spiff up the program to make it walk, then I can have it walking everywhere! I wonder how tricky it would be to set up gyros… Haha! And when I program the two keys, it will be punches and kicks. Not that my MANOI would kick anyone… or would it?
