Download time: Less than 20 seconds to completely fill program memory
Memory:32K Battery Backup
Processor:MC68HC11 - 2Mhz clock 1Mhz instruction cycle
Drive Motors: 2 Long Life Gear Head
Wheels: 2.5" Dia. Rubber
Speed: 0.67 feet per second - fast enough but not fast (slow walk)

Recharge Time: 15 minutes
Battery Life: 10-12 hours no motion, 2 hours with constant motion
Memory Backup in Off state: Manufacturer claimed current draw should protect program for several months over a year, but never tested.
Cost: RWP kit - $599 ($525 from webbooks.net)
6 NiMH C cells - $30
MRC SuperBrain Recharger - $40
Expansion board and connectors - $40
ELTEC Pyro Sensor - $40
Additional Behaviors Implemented:
track age variables (time since boot, max time since boot, time since load, total run time)
track average, max, minimum sound levels
warn of impending low voltage condition
output strings in morse code
sing "hava nagila"
periodically say a few random phrases in morse code
My minimum "dream" for this bot is to add:
a) an IR beacon in the environment
b) scanning and recognition of an IR beacon
c) docking station with power contacts
d) ability to dock with the docking station
Then I hope to add:
wall following behavior
human following behavior
obstacle "evaluation" behavior - (determine the shape of an obstacle - no useful value but ...)
playful behaviors - dancing to music beat, spinning, waddling, squares, circles
