Hi All,

I have been a Java Robot guy for some time (Author Definitive Guide to  
Building Java Robots by Apress) but want to do some stuff with Ruby but  
I am  
limited by two things: web cam capture and serial communication and I  
was  
hoping to avoid C.

Are there any gems or scripts out there to help me out? I’ve Googled but  
can’t find anything…

Thanks in advance.

Cheers,  
Scott

I use ruby-serialport:

[http://rubyforge.org/projects/ruby-serialport/](http://rubyforge.org/projects/ruby-serialport/)

For webcam capture, I’ve been shelling out to mencoder. I would like to  
see an all ruby solution though!
