 | | Studless building techniques
|
|
I am working with a couple FLL teams, building with the NXT. I am having a little trouble coaching them on studless building techniques, as it is still a bit of a new concept to me as well. I'm sure I've seen presentations or how-to's on the subject (...) (18 years ago, 3-Oct-06, to lugnet.technic, lugnet.robotics.nxt, lugnet.robotics.edu)

(...) You can do just about anything with one line of code if you count user subroutine and user macro calls as "one line". The "Rotate" macro in your example expands to four lines of code that sets up and calls a user program subroutine that is (...) (18 years ago, 2-Oct-06, to lugnet.robotics.nxt)

(...) That's just... weird. I've never managed to get something like that. The sequence beam seems to be pinned to the lower edge of the Loop structure, so that even if I make the loop wider, I still can't get to the blind end of the sequence beam. (...)

(...) This is incorrect. There is no "setout" opcode in RobotC. RobotC uses a proprietary commercial alternate firmware with a completely different set of opcodes and virtual machine functionality than the standard NXT firmware. Unfortunately, the (...)

Hello, I got my Mindstorm NXT set a few weeks ago. Have built and programmed all the modells that was in the program that came with the set. And now started to make my own robots with the NXT. The NXT-G program looks great and is easy to understand (...) (18 years ago, 2-Oct-06, to lugnet.robotics.nxt)

If you want to try something a little different, use RobotC to do this. There are several advantages to this: * It can be done with one "setout" opcode. * The RobotC PID algorithm for this type of movement is different than the NXT-G (...) (18 years ago, 2-Oct-06, to lugnet.robotics.nxt)

(...) The NXT firmware does not support a single operation which has the motor run to a specific tachometer limit and then brake. The only way to do what you would like to do involves several operations. But you can wrap it all up into a reusable (...) (18 years ago, 2-Oct-06, to lugnet.robotics.nxt)

I started playing with NBC, and wanted to run the motor until it hits the tachometer limit, and then brake. I have been unable to make this happend with one setout opcode. Is it possible? Is it possible to make the opcode wait until the tacho limit (...) (18 years ago, 1-Oct-06, to lugnet.robotics.nxt)
