abstract class RobotBrain extends AnyRef
The class RobotBrain represents the "brains" (or artificial intelligence, AI) of virtual
robots that inhabit two dimensional grid worlds. A robot brain is equipped with an algorithm
for determining what a robot should do during its turn in a robot simulation. In other words,
a robot brain is capable of controlling the actions of a robot body.
Concrete classes that extend this class need to provide implementations for the abstract
moveBody method; each such concrete class can represent a new kind of robot behavior.
Some subclasses are also expected to override the mayAdvance method.

- abstract def moveBody(): Unit
Moves the robot: causes it to change its location, turn around, or whatever else the robot does during its turn.
Moves the robot: causes it to change its location, turn around, or whatever else the robot does during its turn. What this means in practice depends on the type (subclass) of the robot brain.
moveBodyis called by the brain’s controlTurn method every time the robot brain gets a turn, unless the robot is stuck (as defined by isStuck).This method assumes that it is never called if the robot is broken or stuck.

- def advanceCarefully(): Boolean
Moves the robot one square forwards, if there is nothing there.
Moves the robot one square forwards, if there is nothing there. If that square isn’t empty, the robot does not move, so this method never causes a collision.
- returns
trueif the move was successful and the robot is now in the next square,falseif it was blocked

- def isStuck: Boolean
Determines whether or not the robot brain considers the robot to be stuck.
Determines whether or not the robot brain considers the robot to be stuck. A brain considers the robot stuck if and only if all the squares surrounding the robot contain unpassable obstacles, as defined by the mayAdvance method. Only the four nearest squares in the main compass directions are considered.
- def location: o1.GridPos
Returns the location of this robot in its robot world.
- def locationInFront: grid.GridPos
Returns the coordinates that point at the square that is immediately in front of this robot.
- def mayAdvance(direction: o1.CompassDir): Boolean
Checks the the square that neighbors this robot in the given direction to see if it contains something that the robot brain considers an obstacle.
Checks the the square that neighbors this robot in the given direction to see if it contains something that the robot brain considers an obstacle. This method is abstract; different kinds of robot brains will have different definitions of what counts as an obstacle.
This default implementation (which may be overriden by subclasses) does not consider anything to be an obstacle. Robots that rely on this default implementation are willing to move in any direction and never consider themselves to be stuck (see isStuck).
- def name: String
Returns the robot’s name.
Returns the robot’s name. If the name has been set to the empty string or contains only whitespace, returns
"Incognito"instead. - def name_=(newName: String): Unit
Changes the robot's name to the given one.
Changes the robot's name to the given one.
Note to students: In Scala, a method whose name ends in an underscore and an equals sign -- like this one's -- can be called using a special syntax. For instance, this method can be called either with the statement
bot.name_=("Bob")or simply with an assignment statement:bot.name = "Bob". You won't find many uses for this in O1, but it's nice to know nonetheless. - final def ne(arg0: AnyRef): Boolean
