Why Use Legos?Why Use Legos?

Popular Readily available No soldering required Quickly experiment with alternate

physical designs Mindstorms, Technics, etc. are easy

to program

RCX IssuesRCX Issues

Hardware limitations of older technology

Iconic programming environment hides a lot of details Good or bad depending on what you want

to emphasize Issues with Java tools for RCX

“non-standard” JVM, tools Some language inconveniences (still?)


12

What is this JCX thing?What is this JCX thing?

Lego-compatible hardware Java bytecode is the machine language Standards-based JVM and full language

J2ME CLDC 1.0-compliant Real-time extensions to Java language

Can compile and execute code using J2SE Don’t use classes that aren’t part of J2ME CLDC DO stub out hardware-dependent sections of

code Only have 3 units Not nicely packaged like the Brick
