(...) I think I have one at home that I could part with. If you're interested, send me an e-mail and I'll check if I still have it. -Elroy (19 years ago, 4-Aug-06, to lugnet.robotics)

With the kit? Bad joke, I know. You could try and explain to Lego that your cd has exploded into fragments and would like a replacement. If that doesn't work send me a mail off list and I'll see if I can help. Linmix (...) (19 years ago, 4-Aug-06, to lugnet.robotics)

Got bored with my old site design and decided to redo it... Some things of interest: :: added new pics and info of mods I did to DomoinoBotNXT - it now uses 4 motors using the Mindsensors MotorMux MultiPlexer and NXT. I also programmed it in RobotC (...) (19 years ago, 4-Aug-06, to lugnet.robotics)

|
|
(...) It's just software - otherwise they are essentially identical. Actually, the 1.0 hardware is the best because it has the external power socket - which was absent from the 1.5 and 2.0 RCX. The 2.0 set has a USB infrared tower - the older (...) (19 years ago, 3-Aug-06, to lugnet.robotics)

| | 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)
