"Chiisai" by Scott Davis
"Chiisai" has the honor of being the "First"
nano-sumo! Scott's pioneering effort building Chiisai was long and
tedious. It took more than two months to complete. This first design
utilized a single line sensor which has had some trouble running off the sumo
board. Scott has since resolved this problem with an improved line sensor
design. The robot drive train is based on highly modified Combat DigiQ
gears and motors. The bots 96:1 gear ratio puts it's power to the
board with hacked slotcar tires and wheels. Scott describes the tires as
having "almost illegal" traction! Haven proven his design
with this robot, Scott is already hard at work on Chiisai-II which will feature
additional innovations including dual line sensors, custom gearbox, custom
wheels, and a further size reduction of about 1mm! Scott will be given the
honor of introducing the first ever Nano Competition at RoboMaxx 2003 in Grants
Here are some of
Chiisai's main components:
proximity detectors, 3mm infrared LED's, Hamamatsu P5587 photo
reflectors, MegaBitty controller, 1/3CR 3 volt Lithiums,
Hacked slotcar wheels, Modified Combat DigiQ gears and motors.

"Nano-Scoop" by Casey Holmes
"Nano-Scoop" was built to compete at RoboMaxx 2003 in Grants Pass, Oregon.
Casey says the name Nano-Scoop was decided on for obvious reasons! The
robot is built around Monty Goodson's Atmel Mega-8 based "MEGAbitty" robot
controller board. The infrared seeker, line sensors, and chassis
components are all custom made. The robot's drive train consists mainly of
parts liberated from GWS Pico-BB servos. The wheels are made from printed
circuit board material and feature O-Ring tires. Before RoboMaxx, the
robots external power connector (small pins sticking out on top) will be removed, and the 5mm IR LEDs will be replaced with
smaller 3mm parts to provide more battery room. The current batteries will
be replaced by Kokam Lithium Polymer rechargeable types in the final
configuration. Casey intends to make all the parts for Nano-Scoop
available to other builders when it's perfected. If you are interested in
any of these parts, you can email Casey at firstname.lastname@example.org
