 | | Upgrading RCX to 2.0
|
|
My first Mindstorms kit is the NXT but I have found some interesting projects for the previous generation RCX. My basic question is, is the upgrade from say a RCX 1.0 or 1.5 to 2.0 just a software update via your computer or is something that has to (...) (19 years ago, 3-Aug-06, to lugnet.robotics)

| | NXT and ROBOLAB 2.9
|
|
Here we are with our first NXT robot, a simple sonar wall-avoider. We are using ROBOLAB 2.9 as we want to continue with the ROBOLAB structures. This allows easy migration from RCX to NXT. ROBOLAB 2.9 uses a replacement firmware for NXT. Very (...) (19 years ago, 3-Aug-06, to lugnet.robotics)

| | RE: NXT Motors -- Speed vs Power Level
|
|
(...) I've done the same measurements/plots and found same linearity when 'brake' on inactive PWM cycles is used. Not so good when 'float' is used. This leads to a conundrum that I simply can't explain. If you use 'inactive brake' mode the motors (...) (19 years ago, 3-Aug-06, to lugnet.robotics, lugnet.robotics.nxt)

| | Re: NXT Motors -- Speed vs Power Level
|
|
I tried to plot power levels vs angular speed (in rad/s) and discovered goooood linearity ( remember how non-linear was RCX PWM)? The PID loop is a great idea, and I suppose that PID parameters should be tweakable. In SDK or HDK ( don't remember (...) (19 years ago, 3-Aug-06, to lugnet.robotics, lugnet.robotics.nxt)

| | Re: NXT Bluetooth on Intel Based Macs
|

(...) Unfortunately no. NXT-G is currently a PPC app so it has to run under rosetta. Bluetooth is unavailable to apps running under rosetta. You can connect to it via bluetooth outside of NXT-G though if you write a program to communicate with it (...) (19 years ago, 1-Aug-06, to lugnet.robotics, lugnet.robotics.nxt)

| | NXT Bluetooth on Intel Based Macs
|
|
Has anyone got their NXT to work on one of the "new" Intel based Mac systems using the OSX operating system? Out of the box, I've heard NXT-G only supports USB connections on Intel Macs. But through standard OSX functionality you're able to set up a (...) (19 years ago, 1-Aug-06, to lugnet.robotics, lugnet.robotics.nxt)

| | Great Ball Contraption at BrickFest '06
|
|
There has not been a great deal of public discussion about having a Great Ball Contraption at BrickFest '06, but there WILL be a GBC at BF06. If you missed your chance last year, when we had almost fifty modules, now is the time to start building. (...)

An explanation of when to use and when not to use the new NXT motor speed control option. The RCX supports only a motor power level control where the input is the percentage of time that power should be applied to the motor. The NXT supports not (...)
