[Lab] intermediate to advanced 1.5h arduino workshop

[Darcy Whyte]

After discussion here's a candidate project for a workshop..

It's to make Rolly Bot http://inventorartist.com/rollybot/.

The difference is it will made to fit the Uno and standard breadboard since
everyone probably has that.

The positives:
-The frame goes together in a couple of minutes and everything else
(including servos) goes in place with elastics and straps and stuff.
-It can do locomotion with a fairly limited bill of materials.
-It can still have as many and whatever sensors one wants.
-It's a breadboard and arduino on wheels.
-It's easy to maintain (no standoffs or anything with layers of components.
-No castor and big wheels so it can go on carpet or floor.
-Because the belly of it is a swinging gondola it invites the programmer
into the non-blocking code style since it needs smooth acceleration.
-It's a simple platform for the basics of locomotion, dead reckoning,
object avoidance and much more.
-It's painfully simple so people are screaming to modify it when they see
it so it will invite them onto whatever 3D printer, CNC rotary or laser
cutter they have access to to make their own version.

On the bad side:
-The servo's need to be hacked into drives.

So here's a bill of materials for the workshop and itinerary.

BOM Kit
-rolly bot frame
-two servos
-rubber bands and straps

BOM Participant Already Has
-Uno or any arduino
-Small breadboard
-jumper wire
-sensors

Timeline
15m before start time social
Start: Fast intro and walkthrough of project
15m in: Walkthrough of reference circuits and code  Description of
challenge.
30m in: start challenge
Party till end of timeslot which is an hour or venue closing whichever....


Possible reference circuits and code:
an IR remote version
and an IR wall sensor
an array of line following sensors
a light following or light avoidance version

Possible challenges:
-First bot to roll from a platform marked with tape to another piece of tape
-First bot to follow an L pattern defined by tape on the floor and also
with an obstacle just before the turn for the bend.
-First to follow an oval pattern of tape.
