 | | NXT Motor Encoder Accuracy and Dead Reckoning —Dick Swan
|
| | | 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)

| | | | | 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 (...)

| | | | | (...) 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 (...)

I took my floor cleaner robot, Rosie: (URL) a two-block NXT-G program (in a loop): (URL) created a robot that I think has the accuracy of "Peeves", as seen here: (URL) appears to return within a couple cm each time.
