Day 3: A RETROSPECTIVE

or "words words WORDS"

So, posted a day late because I took somewhere between 3 and 4 naps yesterday instead of updating,
I present RDS DAY 3: A RETROSPECTIVE.

LOOK AT THIS NEATO THING-

MO "the monster" Mortimer

Mortimer is an RDS Cricket, a bigger, brawnier and better cricket.

He's got a pair of monster motors that can keep track of revolutions, an infrared sensor and a touch switch on the front end.  

And thats not all! there are a tonne of slots where inputs and outputs can be plugged in-

    3 motors even! (amazing!)

AND A WHOLE BUNCH OF CODING HAPPENED TOO!

CHALLENGE "a rather excessive number of code stacks" 2

Counter and clock turn Mo left and right by turning only one motor on at a time. It's pretty dang chill.

Bounce and Bounce2 over in the lower left allow Mo to bounce back and stop when he collides with a wall, or hand, or cat, or rocketship or whatever.  Also pretty dang chill.

Part of challenge two is getting Mo to stop at 1.5 meters by various means.

First by simply turning on the motors for a set time.

     but of course that is too easy.  That is where stack RDtimer comes in.  With this we can measure the amount of time it takes by running Mo the distance then stopping him with the touch sensor.

     works out pretty neatly, but gosh did we need a lot of help to sort that out.

Then by using the rotation counter built into the wheels.  

    That's RDcount  It works a lot like RDtimer to allow us to know what number to plug into the stack to it's right, which runs the motor 'till it reaches that number. 

     1500 (what the heck kind of unit is it? I don't know, I don't know)

     

And darkstop uses the light sensor to stop Mo at a line of electrical tape.  

Changing the resistors in the RDSCricket made the sensor much more responsive-

    Sometimes he even stops when shadows from his wires get in the way! Bonus!

OH MAN, BUT EVEN COOLER THAN ALL THAT JAZZ-

ESCAPE.

THE COOLEST THING.

Using the randomization function and the bounce2 stack we built before we can get Mo to traverse and escape from an obstacle course.

Definitely the coolest thing.
