Revision as of 10:58, 5 February 2007

This program is a basic autonomous behavior for Roomba and can be used as a starting place. Where you should be looking in this sample code is the "ROOMBA PORT"

   // Program: ROOMBA_TEMPLATE
   // Description: - This a template for any Roomba program. In order to use this, simple place code in the 'while' loop in place of "// ((>>>>]]}- PLACE CODE HERE -{[[<<<<))"
   //              - As a Disclaimer, this loops much more complicated than it is...
