XX. Final Project


Concept / proposal for project

Project plan... list of tasks:

develope / document concept how will bots communicate?  - explicit language (IR, Wireless etc.), Implicit (range to companion, color of companion led, marks left by companion)
list sensors - could use step response but with tx on one bot and rx on another to do basic range tests
investigate arena
investigate motors - micro motors or servos?
investigate IR comms
investigate sensors

ORDER PARTS!!!!

Finish IRQ serial code

design final arena
design final bot PCB / Chassis
design PC comms too
design a composite body shell

write initial test pc sw

make arena
make single test bot
write initial functionality test software
make second/third test bot
write final bot sw
write final pc sw
test

write up






Final project UI?
==========
Make rule sets.
Upload rule sets.
Start / Stop robots
Show robot status's - input states relating to rules





Motors and wheels
============
mini rc heli motors? cheep enough, shipping times are too long, need to make gears and these are too big when laser cut
gear head motors? Too large and heavy, even the smaller ones.
Of fthe shelf robot gearboxes? Too large and heavy
Micor servos?  Easy to mod for continuos rotation, needs mounting braket

Need to design a mounting bracket for servos
Need to design some wheels
Need to decide on 1 wire (pwm) or 2 wire servo control
Can I try to keep the pot for posn sensing?  or use photo transistor and slotted wheels?
