 | | GA in RCX
|
| - Anybody out there got any experience with Genetic Algorithms in LegOS, anybody willing to give me a little help in getting a handle on it, I'm considering a final year CSSE project using the RCX, and would be interested to here from anyone who's (...)

| (...) No- I should have been more clear: PC->tower->robot automatically turns on the tower and is therefore pretty robust (whereas the robot has no way to turn on the tower once it has gone off.) There is no way to use laptop IR to talk to the (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)
| | | | | RE: RTC
|
| (...) Glad to hear it. Unfortunately, I'm also a student, the sysadmin, a programmer, and just general (computer) handyman, so I don't get to play with the robots all the time. (...) I see. So I can use regular laptop/PC IR to comm with the robot (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)

| (...) Once upon a time, I was paid briefly to do it to. Certainly the best summer job I will ever have. (...) FYI, The main limitation with the IR, assuming that your room is reasonably IR reflective, is that the tower turns itself off and so it can (...)

| (...) Right. (...) Yes. User moves mouse -> applet sends signal to server -> server sends signal to robot. (...) Great! This is just what I wanted. (...) I'll do that. (...) I was also looking for this. Thanks :) Thanks much for your help, Nils (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)

| (...) It is really fun ... some of the time ;) (...) Yeah, I kind of thought that IR may not be so good, but I'm sure that I can find some ways around that. (...) That's an idea, although the data acquisition system primarily measures stress, (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)
| | | | | Re: RTC
|
| (...) Quick note about legOS: it is a replacement firmware for the Mindstorms, designed to allow you to write programs in C that run /on/ the robot itself. Not sure exactly what you mean by real-time, but I'm guessing that you mean something like (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)

| Hello, I have a few questions about legOS, but I know absolutely nothing about it or about the Lego Mindstorms. I am involved in a project at my company to provide real time control of a robot (with one of our data aquisition systemes mounted on it) (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.legos)
| | | | | Re: random
|
| What version are you using? I believe random/srandom are broken in all non-CVS versions of legOS. To get the CVS version, head to (URL) and follow the instructions on that page. Should work fine- I just tested the new random() two hours ago and it (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.legos)
| | | | | random
|
| Hi! Back again with more problems. I want to use random() in my programs and looking in stdlib.h it looks like it is implemented. It says: extern long int random(void); extern void srandom(unsigned int seed); When I didn't have stdlib.h included, I (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.legos)
