(...) I've played with it a good bit. It seems to be extremely accurate, in that one motor will slavishly follow the other - you can do demos like set a Move block to drive forward 10 rotations, and while it's trying to do that pick up the robot and (...)

Dick, the article you referenced with the PID controller is excellent. I spent a lot of time trying to do a straight line with an RCX model a few years ago, but with a different approach: It was track-driven and the drive shaft extension on each (...)

Has anyone done any experiments on the accuracy of the NXT motor "move to" block? If so, can they post their results or impressions? I know NXT supports PID calculations to synchronize two motors and run in a straight line. Can you use this to drive (...) (18 years ago, 13-Aug-06, to lugnet.robotics.nxt)

(...) I played around with this a little bit, trying to confirm what I've been told. It is possible to have an NXT connect as either a master or a slave, but not both at the same time. I'm sure this is true. Here's what I did: I took three NXTs with (...) (18 years ago, 13-Aug-06, to lugnet.robotics.nxt)

(...) As I was working on my ruby-nxt module, I managed to get the nxt to connect to my laptop as both a master and a slave. On my laptop (a MacBookPro) I created an incoming bluetooth serial port and an outgoing serial port on the DEV-B device (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt)
