LED Star Pumpkin

Posted by Erin, the RobotGrrl on Friday, October 31st, 2008

I did make something for Hallowe’en… it isn’t much, but it’s just LEDs in a pumpkin in the shape of the star. The most time consuming part was cutting the wires and soldering them… plus, I had to solder a 1K Ohm resistor to each of the positive leads too. Then, I had to shrink wrap it so it wouldn’t short out (like some of the LEDs on BubbleBoy short out because I didn’t shrink wrap them).

It was okay- I wasn’t too pleased with the end result because I didn’t place the points on the star right… and I wanted to carve it out.

I knew from the start though that I want to re-use these LEDs, so I have them all connected into a small black box. Inside of the box is an Arduino - a RBBB. On the outside of the box held together by tape is the 9V battery and a latching switch.

The program basically cycles the LEDs like a marquee in HTML, then blinks them “seizingly” fast (LOL).

I think I may put the LEDs up in my window… it might look cool!

Shuffling Robot

Posted by Erin, the RobotGrrl on Wednesday, October 29th, 2008

Instead of having my humanoid completely lift its foot off the ground, it “shuffles”. At least one part of the foot remains in contact with the ground. (It does work when there is no ground underneath the foot, though)

I finished the right leg on Tuesday… I worked on the left one today, and will hopefully finish it off tomorrow so I can spend some time on it on Saturday (and make an insightful blog post for once)

What I’m interested in seeing is what is the maximum speed the robot can go at, without tipping over. Since I’m coding it in slow-motion, I may not account for all of the possible moving parts when the robot is going faster.

Robot motion is pretty cool stuff- it looks easy, but it really isn’t

I’ve also been working on a few other things… More on that (hopefully) tomorrow or Hallowe’en.

Humanoid Walk

Posted by Erin, the RobotGrrl on Saturday, October 25th, 2008

This entire week I have been working on MANOI! (and iPhone apps)
I discarded the idea of having a separate TX line- as the SoftwareSerial stuff never worked properly.
Right now I’m in the process of mapping out a way for the humanoid to walk. It’s intensely difficult… So, I’m doing it with pencil and paper… then I’ll code it into the Arduino, and find a protractor to double check all the angles.

(Hey- my plan sounds FANTASTIC in theory! I guess this will mean I will end up doing everything BUT the plan )

I’ll probably make a back-dated blog post on Wednesday as that is when I got the robot to balanced, and it’s a pretty significant milestone
My “jello world” iPhone app is coming along nicely. I like it a lot, hopefully I’ll be putting it up in the App Store in the middle of next week

Prizes? For me? Wow!!!

Posted by Erin, the RobotGrrl on Monday, October 20th, 2008

Apparently I won a prize for placing 10th in the DVICE MAKE Cylon competition!! I got a MAKE the FIRST YEAR (autographed) boxed set of 4 zines, and a 1 year sub to SciFi mag! :D!!

The SciFi mag has Chuck in it… coool!!

That made my day! Definitely worth paying the $30 for shipping. At least I got a prize!! (Remember: I wasn’t even eligible to enter this competition) =P!

~~~

So yeah… my robot (MANOI, with the Arduino-SSC-32 to Processing program) WAS working, now it isn’t. I’m not entirely sure what I changed :X! Debugging again and again…

It’s WORKING!

Posted by Erin, the RobotGrrl on Saturday, October 18th, 2008

My testing version of my program for Processing and Arduino to control the SSC-32 is WORKING!
I’ll post a video of it later, once I hook up some buttons, and “clean” up the code.

iPhone!!

Posted by Erin, the RobotGrrl on Saturday, October 18th, 2008

I got an iPhone yesterday!!! Yay!! (belated birthday present)

…Of course, this happiness if a prelude to a TONNE of hard work that I’m going to do. I’ll be developing apps for it!
I’ll still be working on MANOI today though… hopefully finish the Processing - Arduino & SSC-32 program. It’s really difficult!

Maybe I’ll be able to have the iPhone control MANOI some day bahaha

Problem after Problem after Problem

Posted by Erin, the RobotGrrl on Thursday, October 16th, 2008

Wow, hahahaha I meant to post this yesterday! I wrote it all up… then forgot! Haaa woow

It really feels like I’ve been working on this software to control MANOI for ages now. On Friday I thought that I was really close to finishing off- that it would be so simple to send a variable from Processing to the Arduino.

Evidently, that assumption is DEAD WRONG! I have to send it through Serial. This raises many problems, like the possibility that the data might be fed to the SSC as well.

I’m now powering the SSC-32 by the Arduino. It’s plugged in to the Gnd and pin 6, so I can tell it to turn on or off. PLUS, I have a latching switch on the 5V, just in case.

So it almost feels like I can safely say that I’m really close to finishing off. I’m playing around with code that only sends data to Arduino when it knows it will receive it. Of course, when I try to send data to the SSC-32 it messes the whole process.

The moon last night (2 nights ago) was really bright… it looked pretty through my telescope This Harvest Moon is one of my favourites because you can see Tycho Crater.

More MANOI

Posted by Erin, the RobotGrrl on Wednesday, October 8th, 2008

I always have problems adjusting MANOI’s feet. It’s kind of cool that all of the balancing of the robot comes down to its feet. Hardly anything else matters, other than the feet!

My blog posts seem pretty boring without pictures, so I’m trying to keep this short…

So what I’m setting up now is a program to code MANOI! It will be in Processing. I’m going to be using the controlP5 library for all the buttons and the sliders
Hopefully I’ll be able to get MANOI up and running (really) before December! The new Trossen Robotics contest prize is pretty amazing @_@ Imagine winning a Pleo!! Cuteness! The contest is going to be tense.

Since we’re allowed multiple entries, you can be sure that I’ll enter a fugly MANOI (with all the wires and ‘gutz’ showing) and a cute MANOI (with its pretty white shell on with necklaces). I don’t really understand why everyone thinks that something that is cute isn’t a robot. It’s kind of weird
I ordered two of the new ATmega chips. Essentially this will be great for MANOI! MANOI has a Wave Shield on the Arduino, and I’m thinking about getting a shiftOut to control LEDs for a LED necklace. I might even use one of the digital potentometers on the necklace too! BlinkM LEDs would be cool, but it would be a bit over-kill. I’m thinking Blue LEDs.

I’ll also be programming MANOI with many dances… from Thriller to Soulja Boy… seriously.

But, the first step is to get this software programmed up so I can complete MANOI’s home position.

Festive Styrobotz

Posted by Erin, the RobotGrrl on Monday, October 6th, 2008

Custom Styrobots are really fun to make… and they cost the same price ($20). A friend wanted a yellow Styrobot, with green hair with a comb in it, two combs on the cup, and a poem. It was pretty fun to make! Despite the rotation of the pics being messed up… here are some pictures!

The poem on the back is ‘The Road not Taken’ by Robert Frost. It’s a pretty good poem Here are morrrre pictures!

Great eh! There will be 3 NEW Styrobots appearing in my store very soon They’re all Hallowe’en themed.

In my opinion, Battygoo is really cute as are the other ones! Asside from that… MANOI is aliiiive! I’m currently in the middle of making a program to set its home position.

So keep an eye out… the Styrobots will be poppin’ into the shop very soon
