 | | Re: Text languages for programming NXT?
|
|
I'm getting back into Mindstorms after a long hiatus. Let me resurrect this old thread, to see what the answer is in 2010. :-) What text-based languages are most mature and best-supported these days for programming RCX and NXT? Is RobotC still (...) (15 years ago, 28-Aug-10, to lugnet.robotics.nxt)

(...) *NOW* you're thinking like a Mindstorms person ;). Seriously, I'm glad it's working. The 1 ms difference could be due to a lot of things... but if it's not that critical, then it's not a problem. (15 years ago, 27-Aug-10, to lugnet.robotics, lugnet.technic)

(...) Well, I've built a 2 sensor version of Brian's idea using parallel sequence bars (I tried your idea Kevin, got stuck, then Brian chimed in). I just did some testing by building a rig to press the 2 sensors "simultaneously." I was able to get (...) (15 years ago, 26-Aug-10, to lugnet.robotics, lugnet.technic)

(...) I like it! As they say "There's more than one way to skin a cat". I work on computer servers that have 128 CPUs per chip and 512 CPUs per pizza sized box, and I knew that there is no true parallelism here with the NXT :) I like your design, (...)

(...) Thanks Brian, I am hoping to play with all of the ideas, and really appreciate the response. Robotics, programming, and the NXT are all quite new for me, but I already having fun trying out the solutions provided, and learning the G progamming (...)

(...) I'm not sure how much time you have, or what resources... but you might be able to do this with a single set. If you put an arm on each motor, such that "track A" would hit a peg and turn the motor clockwise, but "Track B" would hit a peg on (...) (15 years ago, 24-Aug-10, to lugnet.robotics.nxt)

(...) Well, just for diversity here's a slightly different approach. Make the first block a "Reset Timer" block, then split the program into four sequences. Each is simply a "Wait for Touch Sensor", followed by "Read Timer" block with the result (...) (15 years ago, 24-Aug-10, to lugnet.robotics.nxt)

Thanks Kevin! That gives me a good start. once I get some sort of working model, I'll share with world for some good old fashion criticism. Chris (15 years ago, 19-Aug-10, to lugnet.robotics.nxt)

(...) Yes, change the "wait for 9" to be a "check for 9", and the problem should go away... Loop forever if Touched and distance < 9 { turn on motor } else { turn off motor } Kevin (15 years ago, 19-Aug-10, to lugnet.robotics.nxt)
