Building a Clojure DSL for Lego MindStorm / Arduino Robots
February 2012

Lego
  -parts
    -technic
    -motors (are sensors)
    -sensors
       -touch
       -ultrasonic
       -light
    -brick
      -LCD
      -buttons
      -sound

  -lessons
    -essential parts of a computer: processor, memory, input, output

  -projects
    -vehicles
    -machines
      -gears, levers, motion translation
    -hand-held games +sensors, motors

  -demo

  -code
     -graphical environment
     -many choices
     -Lua
     -Not Exactly C (NXC)

  -benefits
     -nicely packaged products
     -sophisticated features packed in
     -provide low-level access to peripherals

Arduino
  -parts
    -arduino board
      -processor, memory
      -digital I/O pins
      -analog input pins
      -power/ground for external circuit
    -tank
      -model kit
      -motors, selectable gearbox
    -motor shield
      -power motors
      -set direction
      -brakes
      -measure current draw

  -demo

  -benefits
      -all open, go as deep as you want

DSL
  -ops
  -sandbox
  -teaching benefits
     -tinkerable language (like the hardware)
        -tap into the various Clojure/Lisp parts
        -define the operators
        -define the language constructs (e.g. flow control)
        -define/implement variables, scoping, etc.
     -teach that "code is data", it is just text/forms
     -abstractions - emit code in many languages
     -Clojure/Lisp exposure
  -benefits
     -bang for your buck
     -nestle tightly down into Clojure/Lisp parts
        -e.g. use Clojure evaluator to walk the tree, get macros "for
        free", no need to write parser, etc.
     -constructor functions/macros
     -type to dispatch on
     -associative field access


Thanks!
