I designed a small platform with four
independently steerable and drivable wheels to mimic the
Sojourner rover
(Mars, 1997) and adopted the
Handy
Board
to control the vehicle. Sonar rangers, electromagnetic compasses, and
IR devices will help the untethered mobile robot to navigate.

I have written four
educational programs
during my undergraduate studies.
Here is a set of screen shots
from the programs: an
image processing
package, a
cellular automata,
a nuclear
reactor simulator
and something called
Daisyworld,
a program which simulates global warming.

A few years back I got fascinated by three-dimensional box
kites
and two-line stunter kites. I had fun building them, each taking less
than a day to complete. I have some photos on this page.

I created maps using
Xearth
to indicate places I visited around the globe.
I have my own
xearth_markers.list
with the coordinates of the cities that I got from the
National Imagery and Mapping Agency
and from the
USGS Mapping Information.

I have taken many slides
since the early '80s. I created a table mostly for my own reference to
keep track of the boxes of slides, listing the dates, places, and
subjects. I started to scan some of the pictures and linked the
digitized photos to this table. I plan to have more
Kodak PhotoCDs
made in the future.
