Welcome to the Robot Simulator!
The goal of this exercise is not to pass all the tests. Instead, let's focus on the craft. Do you choose to...
- Implement a ton of features hacking ugly code?
- Implement just a few features and refactor them into beauty?
- Strike a balance in between?
During each work session you will pair program with another developer. Sessions may have one or more constraints that you're strongly encouraged to follow.
Included in this repo is robot_test.rb that will guide you.
Create a Robot which:
- has coordinates on an x,y plane that specify her location
- has a bearing of north, south, east, or west
- can turn left and right
- can advance
Beyond the robot itself, create a RobotSimulator which can...
- place a robot at an arbitrary coordinate with a bearing
- take an instruction sequence like
"LARA"and cause a robot to turn left, advance, turn right, and advance
Outside of Robot and RobotSimulator, you're welcome to create any classes/modules that are helpful to your implementation.

Get familiar with the project and use any and all tools/techniques you're comfortable with.
Good Ruby tends to use short methods. Let's push that idea to an extreme.
In this session, write no methods longer than 3 lines.
The lines for the def and the matching end don't count, just the body of the method. Don't exceed 80 characters in line length or use semicolons -- that's missing the point.
Corey Haines will tell you if statements aren't Object-Oriented Programming.
In this session, build your implementation without if statements.
While you're working on being more efficient, code without using the mouse.
Pairing with someone you don't know can be a bit tough. It's hard to share the workload evenly.
In this session, alternate control of the typing after each line of code.
And let's bring back in the ideas of no method longer than 3 lines and not using the mouse.
Think you've got the hang of this problem? Pairing going well? Let's see how well you can communicate through code.
In this session, don't speak. Communicate through code and, if you have to, comments.
The theme of today is JavaScript! By this point you should have a firm grasp of the problem itself, now it's time to focus just on the programming.
First up, let's use any and all techniques available to you -- but it has to be in JavaScript!
You can do great functional programming in JavaScript. In this session, implement your Robot in such a way that it has no internal usage of North, South, East, and West.
Instead, implement a Plane which has a set of functions that handles all the knowledge around directions and coordinates.
Programming is about communication. In this session, when you're on the keyboard you should do no thinking. Instead, one half of the pair should serve as the dumb typist, while the non-typing half dictates everything that should be done.
