  MIBO Kits, Any interest?
 
I'm thinking of putting together a MIBO starter kit which would include: 5 rotation sensors 7 turntables 1 micromotor 1 chain link pack (108 pieces) 1 copy of Jin Sato's book (includes complete MIBO instructions and NQC code) 5 mini-motors 2 RCX (...)

  Gutting an optical mouse - Part I

Hi,does anyone know how to set vision command using java language? Now I am woking on a robotic soccer project. But I don't know how to locate the soccer using vision command. Does anyone can help me? Thanks. (23 years ago, 12-Jul-02, to lugnet.robotics)
 
  Re: anyone know how to check free space on RCX?
 
That is very interesting Jason. It is interesting that mm_free_mem() returns a 16bit value using a 32bit return code. Both int and long are 32bit value on most computers/compilers these days; short would be a 16bit value; and char would be an 8bit (...) (23 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

  Re: anyone know how to check free space on RCX?
 
While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex.

  Re: Ant pheromones

  Re: anyone know how to check free space on RCX?
 
Albert Huang, Sorry for the confusion. "most significant" = upper 16 bits and "least significant" = lower 16 bits (the free memory is a 32 bit value). If you write the values out, you will get the 32 bit value (both values are hex) ... for example: (...) (23 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)
