Post by: airman00 on August 13, 2007, 06:23:02 PM
Heres the new base for my robot. Its 3' 1" high on 21" square.
Go to my blog http://erobots.blogspot.com/ to see pictures.
If you have questions feel free to ask me.


You likey???

I realy do likey!

I think you should take a look at http://leafproject.org/ (http://leafproject.org/).

As I was saying in a previous post, I am also building a robot such your butler robot. I will make a new thread with a description and pictures.

NICE STUFF!

I didn't get the chance to make a metal frame yet....

That animated head on the laptop is really cool dude!

Leaf Project is a source of inspiration for me too!

My robot is here: http://www.societyofrobots.com/robotforum/index.php?topic=1764.0 (http://www.societyofrobots.com/robotforum/index.php?topic=1764.0)

Looks really nice!
I'm going to put on a robot arm on my robot today for giving out drinks...

How well did the IR sensors work? How many did u use? Where did u put them on the robot?
Details man!  :Plol

If you look at the photos you will see the locations of the sensors: 3 IR on the bottom front and one in the back, but higher, 3 US sensors higher in the front and one on the head. The IR sensors work pretty good, but have blind spots. US sensors don't work, I have to change the microcontroller. But I can use the camera for driving.

What do you mean by using the camera for driving? How can you get depth perception with one camera???

Camera driving means that the image processing looks for edges, trying to decide if there is an object to be passed... the ER1 software has the possibility to use 2 cameras, one for object recognition and one for driving. But if you use the API, you can swap cameras and only use one camera for one purpose at a time. For instance, look around to find the object you need to grab or go to, then change the function of the camera for driving towards the object, avoiding obstacles in the way. I just tilt down the camera to the proper angle for driving, because the camera has to be calibrated when the robot starts. Actually, it has to be done once, because it saves the configuration immage and it compares the frames it gets with the config frame.

Do you know where I can find such software? That detects edges and navigates accordingly....
