The City Harbor boat hull is plenty big to hold an RCX or an NXT. It could hold three of them end to end, actually. There are studs on the bottom of the hold and along the top, so you could build a cage for an NXT or just stick the RCX directly onto (...) (18 years ago, 19-Sep-07, to lugnet.robotics, FTX)

(...) I've been wondering this myself. I thought it would be soon seeing as the bulldozer came out ahead of schedule, but now it looks like the cables wont be here before october. (18 years ago, 18-Sep-07, to lugnet.robotics)

(...) pbLua supports communication over the RS485(?) port. That's sensor port 4. Using that port, you can connect several NXTs together. You just need a cable that connects to several ports. Steve (18 years ago, 18-Sep-07, to lugnet.robotics)

I suspect that with the proper software (and maybe a special cable), the I2C protocol can be used to network between NXT controllers. I2C is a multi master bus with collision detection, so it "should" work. It's just a SMOP [Small Matter of (...) (18 years ago, 18-Sep-07, to lugnet.robotics)

(...) It's a good thought - in fact, my first attempt was to use the front treaded "flippers" on LNE/Packbot so that Packbot could drive onto a "floatation frame", and either power or deploy its own "water tread" propulsion. That idea fell afoul of (...) (18 years ago, 17-Sep-07, to lugnet.robotics)

[Cross-posted to lugnet.robotics as it's on-topic there] (...) There's no absolutely transparent way to make a program running on one NXT address the sensor or motor ports of a 2nd (or 3rd, or 4th) NXT. However, a lot of solutions to this problem (...)

Not that I've tried it (of course) but it seems that if were to use the treads with small paddles attached, it would push the splashing part to the rear, give skid steering, and sill provide good propulsion, similar to the corkscrew idea. Chain (...) (18 years ago, 17-Sep-07, to lugnet.robotics)

(...) Oars are nothing but highly asymmetric paddle wheels. Yes, I know, that's a bit simplified, but still splashes a lot unless you have the high amount of control over force curves, blade angle, etc. that an experienced rower has. Just check out (...)
