Ok, I don't think this is too far off-topic.
At the JavaOne keynote presentation this morning in S.F., James Gosling and
Kay Neuenhofen of Sun Microsystems demonstrated Mindstorm tanks controlled
from Palm V's running KJava aka MicroJava.
They also said that the Mindstorms and the Palms were proxied into Jini
devices by a Sparcstation server.
You can watch a webcast of the presentation at
www.graham.com/broadcasts/sun/JavaOne-99/keynote1/keynote1.html
The Mindstorms segment runs from 1:30:18 thru 1:35:00 (that's 90 minutes
from the start), so you might want to fast-forward a bit.
---------------------------------------------
Here's an excerpt (at 1:32:40):
Neuenhofen: The tanks come up first and they implement a controllable
interface and the Palms are then looking for something that implements a
controllable interface and they then start controlling the tanks. So it's a
spontaneous creation of a Jini federation.
Gosling: The tanks themselves are actually not running Java, they're being
proxied.
Kay: The tanks are too small at the moment to run Java so they run their own
proprietary Lego operating system, and ...
(crowd laughs)
They are.

| Since I wrote this, I've seen the setup in person. The Palm V's are connected serially to a Sun PC which broadcasts IR from a standard Lego IR tower to the tanks' combat arena. The messages sent to the tanks use 3 bits for the tank id and 5 bits for (...) (25 years ago, 18-Jun-99, to lugnet.robotics)
