• Goal: Use classic planning to make your hexapod brew a powerful elixir by bringing the right ingredients to a pot and adding them in the right order.
• Approach: You set up a planning problem, using a simple XML data file to describe the initial state, possible actions (with pre- and postconditions) and a goal state. You solve the problem using a search-based problem solver in Java that reads your XML data. Once a solution has been found, you test it by sending the action sequence to your hexapod and see it succeed with the brewing.
• Materials: You start with a simple problem solver in Java and a skeleton of the XML data files.
• Hand in: Zip up your data files and any java source files that you modify and submit via MySchool.
• Deadline: Hand in before 23:59 on Sunday the 11th of March!

• move camera with a-s-d-f and the up and down arrow keys.
• Move Hexapod with u-h-j-k
• M: Enable control camera with mouse

• “RU.AI06.Perception.Sight.Object”
• “RU.AI06.Perception.Touch.Object”

These message contain, in xml format, the information about a perceived object. The Java class Perception can translate itself to and from the xml format and has three variables:

• type of perception
• type of object
• Location to object RELATIVE to the Hexapod

New messages allow you to make the Hexapod quickly go to certain places, pick up ingredients, drop ingredients and add them to the pot where the elixir is being made:

• “RU….”

You can also send the same messages as before to make the Hexapod move itself but NOTE!!! the content is now the degrees with which the Hexapod is to rotate its limbs.

Also, you can send the message “RU.AI06.Instruct.Change.UpdateTime” which will change the update time with which the Hexapod sends its perceptions.
