Hello everyone, I've just built a Microbric Viper robot which uses a laser based obstacle detector to avoid obstacles: http://ashishrd.blogspot.com/2007/04/self-navigating-microbric-viper-robot_25.html[^] I built the obstacle detector using a wireless webcam and a laser pointer. Well, this isn't the first time I'm using a laser based obstacle detector on a robot (I've used them before on computer controlled RC cars)..but this time the robot is able to scan its surroundings by rotating the obstacle detector with a servo. The camera on the robot sends images to a computer..and the computer determines how far obstacles are by checking the position of the laser dot in the camera's field of view. You can read more about it on my blog. :) The robot's microcontroller has been programmed in BASIC! My computer communicates with the robot using IR. Here's MSDN Coding4Fun article by Scott Hanselman on doing this if you're interested :) : http://blogs.msdn.com/coding4fun/archive/2007/02/19/1720128.aspx[^][^] Well, I took a slightly different approach and used a computer controlled PlayStation 2 remote to control the robot. :) Be sure to watch the videos! Hope you like them. :-D Ashish

Nice! Although... having a dog chase a laser is much more fun :) I played around with a similar thing on my Lego NXT, but the sensor picks up too much noise. NXTs communicate using BlueTooth, which is fine for reprogramming but not as fast as IR... although also not prone to line-of-sight problems. IMO, the NXT is a smaller learning curve and less financial outlay, but clearly not as capable as other kits. NXT can be programmed using many languages, including the new MS Robotics Studio. Microbric is definitely very cool, but for beginners without a lot of money, I highly recommend the Lego NXT. (Viper kit might be cheaper, but comes with less "stuff" ... I didn't want to look up the conversion rate to AUD, someone else can google that) You know you are mentioned on their site? Very groovy :)

Excellent, you have a lot of talent that some hitech company would be interested in. The thing you got above other programmerw is the ability to think outside the box, an attribute that is very rare nowadays with the amount of 'IT noise' in the world.
.net is a box of never ending treasures, every day I get find another gem.

Yeah, it has an ultrasound distance sensor, but it gets too much noise. I tried to make a simple radar screen, and you have to scan things 3 or 4 times and average the result... otherwise you get spikes all over the place. Right now I'm trying to make a dog toy that would run away from the dog, and react in some way when he hits it, then go running off in some other direction. Tricky part is that it has to be faster than him, or it's just not entertaining... I think the Microbric parts are a little cheaper than the Lego. Both kits have their advantages...

http://www.smoothjazzy.com/ - see the "Programming" section for freeware tools and articles.That sounds like a fun and tricky project. I'd love see a video if you're successful :) The fact that Microbric robots don't come with all types of sensors (like Lego NXTs), is a good thing for me. It encourages me to make new things..like the laser based obstacle detector. :) This is what makes everything fun and exciting...if Vipers came with ultrasonic range sensors...I wouldn't have enjoyed doing this project as much as I am enjoying it now. I had the fun of making my own obstacle detector! :) Ashish

That is a very good attitude which more young people should have. You should see the Lego forums: "Why can't we have more motors?" More this, more that... no questions about how to do more with what you get. Keep hacking... you're gonna turn out good :) Better than most already... :)
