| | Need help to put sound in Minerva Program.
|
|
A person with a visual handicap is building Minerva. I would like to add sound to the program while Minerva is going forward, another when she is turning around, and another when she locates something to pick up. This will allow this builder to test (...) (24 years ago, 29-Apr-00, to lugnet.robotics.rcx.nqc)

I made some mistakes in the first release, so here is a new version. I've also added counter support. <-Readme.txt-> RCX2 Header file for NQC2.1r2 - 27 April 2000 - James Pritchard rcx2api.nqh - NQC Header file that contains constant and macros for (...)

(...) It seems to me that, given the current hardware, the choices are: send junk or let the tower go dead. My thinking is that if you send junk and trample something, so be it; the tower would have gone dead anyways, forcing you to lose whatever it (...)

(...) Yes. Note that it is only half-duplex. You probably expected that. (...) The biggest issue you might run into is the fact that the IR tower used by the PC times out if it doesn't transmit anything for a few seconds. Unless you have constant (...)

It appears Roblab 2.0 would also be an alternative for your project. Robolab has two different direct modes to control the RCX, one of which is using a remote connection like the Internet. Depending on your direct control requirements, you may want (...) (24 years ago, 26-Apr-00, to lugnet.robotics, lugnet.robotics.tele, lugnet.robotics.rcx.nqc)
