Hi, I'm trying to build the lejos release on UBUNTU linux and I get the following error. Any help appreciated. Thanks, Ted pawlicki@robotnik:~/lego/build$ ant Buildfile: build.xml clean: [echo] saving existing files to .bak files libnxt: [taskdef] (...) (18 years ago, 13-Mar-07, to lugnet.robotics)

Ooh, NXT-Sumo! David, I sure hope you'll be running your "Getting to know the NXT" breakout session BEFORE the sumo contest is held! My NXT remains sealed and unopened on a shelf in my Lego room. I'll bring it, and maybe I'll learn enough to be (...) (18 years ago, 13-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

(...) The question you need to answer for yourself is this: Do I want my robot to to potentially execute both if blocks in sequence or do I only want the second if block to execute if the first condition is known to be false? If you only want the (...) (18 years ago, 13-Mar-07, to lugnet.robotics)

(...) For the RCX wait times are in 1/100 of a second. Is that the same for the Cybermaster? If so the reverse and turn times are a little short (as well as the motor ramp up period). I could see how it would be difficult to notice the robot backup (...) (18 years ago, 13-Mar-07, to lugnet.robotics)

(...) Sorry. I meant to say 'the brick never executes the if statement'. (...) I don't see 1) how I could make an if/else statement or 2) what the benefit would be. 1) If I make an if/else statement isn't 'else' executed always if 'if' is not true? (...)

(...) You assumed correctly. Without the wait the if statement is always executed immediately. I see what you mean: by taking the wait out of the start of the loop the sensors are checked more frequently. That doesn't solve the riddle though, (...) (18 years ago, 12-Mar-07, to lugnet.robotics)

Doesn't this make more sense. (...) The way it was written you hardly ever checked the TachoSpeed because most of the time was spent in the Wait(20). I assume the Wait is in there to allow the robot to get up to speed before you start checking for a (...) (18 years ago, 12-Mar-07, to lugnet.robotics)

(...) I 've done just that, but the problem I describe persists: When the TachoSpeed reported by watching the brick is around 57, the brick doesn't do anything if the response value is set to 62. It does at 66 or 67 but that also makes it impossible (...) (18 years ago, 12-Mar-07, to lugnet.robotics)
