If you want to introduce a new instruction for robots, all you need to do is to modify Robot.java file to let a robot know what it should do when it gets this instruction. The rest of the code should work without any modification.

Currently an instruction is ignored by a robot depending only on its orientation on a border cell. However, there might be multiple conditions, that together would lead to ignoring of an instruction. This is not taken into account in the current version of the app.
