To let them use the kicker:
The spot where the bots need to get needs a liftCenter, and a liftexit. imagine a line from that point to the kicker, and on the other side of the kicker (at the same height) you put another liftexit. This way the bots will go for the liftexit as if it were something special. From that point they're programmed to go for the liftcenter, but in that path is the kicker. They don't even realize they get kicked up. THat's the trick I use. (don't forget the tags)
If you don't get it: open DM-empowered in the editor. The author of this map used this bot kicker sollution.
As for making bots jump off platforms: when it's safe enough they should do it anyway, elseway just put some liftexits on the edge where you want them to jump. should work.
It never hurts to help ...
