As an electronics engineer, my focus would be on circuits and interfaces. I'll
leave the software and firmware to software experts!
Firstly, for the benefit of the program, I'd reverse engineer the NXT interface
(sensor, motor, power) circuits. I have pedigree here, having done it for the
RCX 1.0: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=109570
Secondly I would seek to create the capabilities to do the following:
1) Power the NXT from a 7V AC train transformer, so that static or short range
moving exhibits could run all day without using up the batteries. This would
provide the much sought-after mains power supply.
2) Multiplex more sensors and motors to a single NXT port, to expand the total
number of devices the NXT can control.
3) Use legacy Mindstorms sensors and motors with the NXT, including the more
powerful RC Car motors from a separate power supply, for more powerful robots.
4) Consider creating new sensor types and output devices, such as an LVDT sensor
to measure linear position. Integrate this with LEGO pneumatic valve control
and attempt omni-positional pneumatics.
5) Interface the NXT with earlier RCX devices so people can continue to get the
best out of their earlier products by using the NXT alongside them.
I expect some of these projects to continue long after the development program!
I would post stuff on the web in accordance with the NDA, whether this is to a
restricted forum for the duration of the development program, or more widely
when the information is released from NDA. My overall aim is to help AFOLs and
younger fans get the most out of the NXT by removing any limitations of the
system.
