Friday Night Robotics – Plain Vanilla

Posted by Erin, the RobotGrrl on Sunday, January 18th, 2009

At first, the title of this post was “Mediocre at Best”, but after I typed it all up, I realized that I did do stuff that makes it a little bit better than mediocre! So, I switched it to “Plain Vanilla”. There really isn’t much stuff to do when I don’t have MANOI around!

I started a new project thingy where it is an extremely simple game of pong. The paddles are stationary, but the trick is that one paddle would be controlled by the computer (in this case- an Arduino), and the other would be controlled by the human with a Wii Nunchuck.

The paddles are represented by tiny pink LEDs, and the ball is represented by the LEDs in between them.

There is one LED at the top that is used to signal the start of a new game, and/or a goal.

Since the human player would be using a nunchuck, it would sort of be like Dance-Dance-Revolution where you would have to tilt it a particular way to have the paddle show up. For this, I’m going to use BubbleBoy’s LCD screen:

It will also be able to display the score! ^_^

I got a little bored of doing this due to numerous conflicting errors when I compiled the code, so I switched to my snowplow robot.

I remember having trouble trying to get the two motors to move with this one, so my main goal was to debug it. It turns out that one of the tab thingys on the DC motor was loose!

I had to snap the robot in half in order to transport it, so now the snowplow is waaay too top heavy =) It’s kind of funny!

I really can’t wait to get my Femsapien that I won from the Robots Podcast contest. I’ll play around with it a bit, then I will hack it and put an Arduino in it! One of the things I really want to do is to try making it Twitter. Since I don’t have an ethernet shield, I would probably have the robot (Arduino) send a variable to Processing, which would then twitter, probably using something like this.

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!
