RCX 2.0 adds firmware support for events and resource acquisitiion. The primitives are rather straight-forward. For events, one command beings event monitoring on a set of events, another stops monitoring. If a monitored event occurs, control is (...) (25 years ago, 1-May-00, to lugnet.robotics.rcx.nqc)

Hi Bob, I've attached a modified version of the Minerva program. It plays different sounds for each of the following events: 1. Moving forward : ascending arpeggio 2. Turning around : descending arpeggio 3. Found something to pick up : deedle-deedle (...) (25 years ago, 1-May-00, to lugnet.robotics.rcx.nqc)

Can you post the program please. I don't think the group excepts attachments, So just copy and paste text into a message. I think all that will be needed is to add PlayTone(freq, duration) where an event is monitored. James Bob Fay (...) (25 years ago, 30-Apr-00, to lugnet.robotics.rcx.nqc)

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 (...) (25 years ago, 29-Apr-00, to lugnet.robotics.rcx.nqc)
