Route Generation for GrinBotsII
Here's a quick tutorial covering the basics of route-creation for GrinBotsII.

Their perception of Parthoris
The most important thing the bots need to know are where they are, and where they can go. They don't see the level as we do, but get this information from a series of waypoints, or nodes. Not exactly original or ground-breaking, but it works well.

The route files contain the location of these nodes and a table that describes wich nodes are linked, along with the length of the link. This information is then used to generate another table that tells them the shortest path from any node to any other node. There is also a table that holds information about the location of all the good stuff on a level, such as items, shrines and teleporters.

The placement of the nodes, and the creation of the links between them needs to be done carefully to get the best performance from the bots.
