 | | Powering 9v Trains using the NXT
|
|
To all, I would like to find a way (simple way that is) to power our LTC 9v trains using both the standard LEGO 9v train modulator and the NXT. We have attempted the following: 1- Power the train simply using the NXT and the converter cables. Too (...) (17 years ago, 17-Oct-07, to lugnet.robotics, lugnet.org.us.ulug)

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 (...) (17 years ago, 19-Sep-07, to lugnet.robotics, FTX)

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 (...) (17 years ago, 18-Sep-07, to lugnet.robotics)

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 (...) (17 years ago, 17-Sep-07, to lugnet.robotics)
