 | | 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)

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)
