class Spinbot extends RobotBrain
The class Spinbot represents the "brains" (or AI) of extremely simple robots
that simply spin clockwise and never change location.

- 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

Controls the robot body’s actions for a single turn.
Controls the robot body’s actions for a single turn. If the brain considers the robot to be stuck (see isStuck), this method does nothing. If not stuck, the brain calls its own moveBody method, which carries out the actual robot actions.

- 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 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 moveBody(): Unit
Moves the robot.
Moves the robot. A spinbot simply spins 90 degrees clockwise as its move.

- 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.- Definition Classes

- 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.- Definition Classes
