Sixis: Read the rules from the games in the 1990s, then tell me if you still think the current rules are restrictive on parts. Look at robots from that time and tell me if restrictions stifle creativity. The rules and pictures can be found in a number of places.

Also, you can get some equivalents of the things that you can get at AndyMark through VEXPro, which is a division of IFI.

There are NO restrictions on sensors, except for the $400 component limit and what they can connect to. The Digital Sidecar is a typical connection method. Oh, yeah: if the components fit the cost limit and you meet the connection limits, you could build a co-processor to help the cRIO.
