Looking for suggestions for website

Hey LMR!

I am looking to create a sit like LMR, but geared towards combat robots. So here it is:

http://www.robotskill.ca

I am looking for suggestions from everyone on what type of content they think should be there and how that should be presented. So please shout out let me know what everyone would like to see.

On a side note, we are looking at putting as combat robot league, anyon near ontario Canada please let us know if you are interested. We are also looking at starting a completely autonomous division.

The fascination nowadays is that I could put in “cost ” 30€ or 30.000€. Read more

Live soccer robots on LMR - Software

This post is to help Frits or anyone else get and deploy the necessary software for OddBot's "Live soccer robots on LMR".

Description 
The game will be a multi-player remote control internet soccer game. Complete with cameramen, laser towers and any other silly shenanigans we can think of.

About me

I am a 55 year old computer programmer with 35 years experience as a systems programmer. During that time, I have programmed in over 40 languages professionally.

In the Air Force, I was a ICBM mechanic as a civilian, I started out as an electronics engineer but was so distracted by the idea of programming that I took it up full time. Consequently, I have been able to strattle the fence, one foot in software, the other in hardware. Nowhere has this been more beneficial than in the robotics world.

Dagu's Ultrasonic Sensor testing

I've made some testing with the ultrasonic sensor from Dagu. Tests were made on the platform the sensor is build for, the Asuro. The sensor works pretty well, most of the the time. The range of obstacle detection is from 0..25cm. Sometimes the sensor dismiss an obstacle, when the objects is not directly in front of the robot.

 The video gives some impressions, how this sensor works.

Other robot builder communities

When we started this LMR-thing, there where not really that many robot-builder communities. Now I see them pop up, I just discovered the one that I will post below as a comment to this.

Apparently LMR is still the worlds biggest of it's kind, according to different websites that compare traffic, google-ranking etc.

So, I think it is in place to spread a little of our love, get the other guys some visits!

Shift Registers with Arduino

On this page there is a tutorial for using shift registers with arduino http://www.arduino.cc/en/Tutorial/ShiftOut

The person has attached two shift registers togther by plugging one into the arduino and the second is getting serial from the first register. Would it be possible to attach same 10 shift registers in this way? Would it be slow or inaccurate? Would the code be over complecated? Would there be to much current draw?

Any help is good
