Creates a robot player owned by the enacting player (you). The robot has its ROBOT flag set, so it may use the OUTPUTPREFIX and OUTPUTSUFFIX commands that some publicly available robot programs require. This command typically costs 1000 coins but the amount can be adjusted by game administrators. Some sites do not restrict outputprefix and outputsuffix to robots.
Robots can login to the game much the same as normal players. They are often used to tie games to external processes such as spell checkers (Webster), chat based AI routines (Eliza), etc.
On PennMUSH robots do not exist, and everyone can use OUTPUTPREFIX and OUTPUTSUFFIX.
