robot
robot: [IRC, MUD] n. An IRC or MUD user who is actually
a program. On IRC, typically the robot provides some useful
service. Examples are NickServ, which tries to prevent random
users from adopting nicks already claimed by others, and
MsgServ, which allows one to send asynchronous messages to be
delivered when the recipient signs on. Also common are
`annoybots', such as KissServ, which perform no useful function
except to send cute messages to other people. Service robots are
less common on MUDs; but some others, such as the `Julia' robot
active in 1990--91, have been remarkably impressive Turing-test
experiments, able to pass as human for as long as ten or fifteen
minutes of conversation.
