- How easy is it to write code on standard Java SE / cRIO Java and port it to niRIO?
- What are the deploy times?

1. The Java API is, at this point, the same as the old API. Then again, it's not even all fully functional yet - It's a better idea to use what they know to get things working perfectly before looking to refactor just for the sake of refactoring.
2. You'll be using whatever JRE they decide is FRC legal. The RobotRio is running a RTLinux distro, which makes it very easy to play with.
3. I'm not sure about the C++ version
4. Just load up the FRC plugin for Eclipse, and go to town... personally, I like Eclipse a lot better than Netbeans.
5. Deploy seems a lot quicker - we were going from clicking to driving in under 30 seconds.

1. We didn't time it, but it seems quicker than the current cRIO.
2. Yes, WPI is still heavily involved, and we're using WPIlib.
3. Currently, it's a USB dongle. The final radio hasn't been decided on yet, and last I heard FIRST was looking at a number of options, including the dongle. Nice point for the dongle: No external power, which means no radio resetting due to power issues!

Overall it weighs less. The modules are all small, simple plastic boxes with nice connectors, very light weight.

Do any of you know what the Solenoid Module will be? I've been told it's a CANipede RCM but it looks a bit old to be used in conjuncture with the new hardware.

It is not the CANipede. It's a new module developed by CTRE. It connects to the RoboRio through CAN, and provides:
- Solenoid outputs
- a jumper to switch between 12 and 24V (with an internal boost, you only need to power it from 12V)
- A pressure switch input
- A compressor output
