Its gonna be RAD

Hey all. I was really excited when my EZ-B arrived about a week ago. While it was on its way I was searching around for my first project. Thanks to DJ's great website and Ebay I found what I wanted. I picked up a RAD 2.0 for 15 bucks. It did not have any remote or battery charger (so what). And today I started on it! I hope to post my progress here and open to any ideas you all might have. As you can see I wasted no time before I opened it up!

The RAD 2.0 has what looks like a decent track base with motors and gear boxes (a bit loud when I tried out the motors). It has a physical gearbox selector switch for High and Low gearing (I will need to put a servo on that) which will be cool to mess with. The interesting thing about this guy is that he bends at the waist. He also has two arms that work together to grasp an object. It looks like can bend all the way over and pick up an object on the floor (we shall see). After opening it up I noticed it appears to be a decent thing to start modding.

I have an H bridge on the way for the track motors and I probably going to need another if I want to use the existing motors that control the waist and arm movements. I am thinking of putting in a accelerometer as well so when the bot goes up or down hills it could stabilize itself automatically! It will surely have a distance sensor...just not sure where to put it yet, camera, and probably go with an MP3 trigger. You may notice the circle on his chest...The original toy was remote control and could fire nerflike darts (pretty neat). Not sure I will keep that functionality as I am thinking of other cool gadgets to hook up to him. Tonight I tackled the head movement.....I will post more on that later.....

What can I say, I am super excited about this stuff! Thanks to having a bunch of young boys with lots of legos and kinex around and the handy dandy hot glue gun, I already worked up a possible solution for the head movement. Once I figure out how to get vids up on YouTube, I will post the video. In the meantime...here are some pictures of how I connected up a servo to the head.

Nice Kevin! I can't wait to see your video. And of course any EZ-Script you have worked out might be helpful to others.

Hi Robotmaker,

I got the speaker at Bed Bath and Beyond, but it is not an IHome speaker.., I tried to find it online, but could not.....it was one they had in the store though...cost about 10 bucks...that was the hard part...finding the right size..I did have to wrap some rubber padding (the kind you line toobox drawers with) around it twice to get a snug fit.....that may work with the ones you have....then some hot glue...if i get back out there I will try to find the vendor of it.
