Steve Baker has done some wonderful experiments on the accuracy of the rotation sensor which can be read at the URL at the end of this message. I have a alternative explanation for the inaccuracy in the rotation sensor when used with the standard (...) (24 years ago, 12-Jan-02, to lugnet.robotics)

(...) Those would be the RCX "mailbox" messages...the ones that RCXs send to one another using SendPBMessage. Spirit.OCX can do lots of things, but it can't cause the IR tower to send messages to the RCX. --Ian (24 years ago, 12-Jan-02, to lugnet.robotics)

About a year ago I was inspired by discussions about how to get an RCX robot to make perfect 90 degree turns and also by an interest in traversing mazes and collision avoidance. I had an idea to navigate and turn using an approach similar to a (...) (24 years ago, 12-Jan-02, to lugnet.robotics)

NQC is intended to write programs that run on programmable bricks (RCX, Cybermaster, and Scout). The 9751 is more like a peripheral for the host computer, so you'd need some tool that writes programs that run on the host. I think I've seen (...) (24 years ago, 12-Jan-02, to lugnet.robotics.rcx.nqc)
