Four % formating with only three arguments to format. It cannot work...

print "This robot is named %s. The current speed setting is %d, and %s
has a lifetime of %d" % (self.name , self.speed , self.name, self.lifetime)

...

May try this too:
print "This robot is named %(name)s. The current speed setting is
%(speed)d, and %(name)s has a lifetime of %(lifetime)d" % self.__dict__
