I'm embarrassingly new to Mindstorms. My first Mindstorms system (RIS 2.0) was purchased just two weeks ago. I'm still very much a novice. With that in mind...I have a few observations/questions of my own: 1) I'm stunned by this announcement! After (...) (18 years ago, 6-Jan-06, to lugnet.robotics)

(...) My hope is that this is some sort of bus system which will allow someone (possible LEGO itself) to make a "hub" which you could use for this. There are three ways to do this: the hub could do the logic operations itself (perhaps with a switch (...) (18 years ago, 6-Jan-06, to lugnet.robotics, FTX)

(...) I was just thinking .. the rumors about this year's trains are that they'll be remote controlled battery-powered units (probably so LEGO can use cheaper track without the metal conductors) .. those would fit the bill exactly. Bluetooth (...) (18 years ago, 7-Jan-06, to lugnet.robotics, FTX)

(...) Well, I am pretty sure the control for the trains is IR. That's what Jake said and that is what the little black bump is on the side of the trains. I am sure TLG will do their Manas type IR serial interface, with message packets at different (...) (18 years ago, 7-Jan-06, to lugnet.robotics, FTX)

(...) I threw my name in as one of the 100 early testers (who here hasn't :) and one of the questions was on FLL involvement, and a willingness to write FLL documentation. That leads me to think that they are definitely considering extending the NXT (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

(...) The NXT FAQ addresses this question - it says that both the RCX and NXT will *both* be allowed in the 2006 FLL season. That should make for some very interesting decisions and comparisions. It also suggests to me that along with the MUPs we (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

If they're looking to the future, I would expect it to be a digital bus, much like something my robo-club has been thinking about. It could be I2C or CANN-based, or proprietary (unlikely). Six wires makes sense -- ground, bi-directional signal (2 (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

(...) I just saw Lego's definiton of a servo motor. It resembles a industry servo, not a hobby servo. In the hobby servo, the closed loop is done in the servo electronics, but in the industry servo, the closed loop is done in the controller. (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

(...) This all makes some sense, though it seems strange to put a digital board in the servos, but not do the control there. In any case, I think my first project will be to figure out how to use the USB port to connect the NXT to a more powerful (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

(...) I was wondering if one could make a two port host device with its own power source (battries). It could be relatively simple, where one host port polls the device port of the NXT to find out if there is anything to do, and then the second host (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

(...) So you are saying you have a sort of mini-host acting as a bridge between connected devices like a NXT and something else. That sounds like an interesting idea ..... I think one of the reasons why hosts are tricky and devices are easier is (...) (18 years ago, 8-Jan-06, to lugnet.robotics)
