AntLog is a tool I have written to automate Peter Waller's double-elimination sheets.
It is a set of macros in an spreadsheet template. It will run on any version of or LibreOffice from 2.3 onwards. and LibreOffice are available for Windows, Linux and Mac OS. AntLog supports competitions for 8 to 128 robots.

I have also drawn up a set of charts to exactly match AntLog. Handy for a paper back-up or can be used in their own right as a low-tech solution.
