I don't frequent robotics, but I figured I'd post about the class I'm taking. So far, we haven't done any control, just building mechanical stuff. Here are the pictures: (URL) course web site: (URL) Lambrecht bram@cwru.edu (URL) (25 years ago, 25-Jan-01, to lugnet.robotics, lugnet.robotics.edu)

(...) But I don't think you did what we reported IS the problem... Did you run the motor FORWARD, then REVERSE so we can see the missing positions? That's where the errors come in. Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (...) (25 years ago, 25-Jan-01, to lugnet.robotics)

(...) I think the PIC series of microcontrollers have some sample code for reading quadrature-type rotational sensors (a la mousewheels). Perhaps one could design a PIC-based intermediate module that was dedicated to reading rotational sensors (...) (25 years ago, 24-Jan-01, to lugnet.robotics)

(...) OK - time for the rigerous scientific approach here (well - OK - the half-assed semi-scientific Steve Baker method :-)... I'm typing this email as I run the tests...so right now, I don't know the answers... Test 1: Connect two rotation sensors (...) (25 years ago, 24-Jan-01, to lugnet.robotics)

Thanks for all the inputs! After testing out the rotational sensor with teh 25:1 gearing I have discovered that it will count 402 clicks for 1 rotation. So the sesnor is reading only 2 extra clicks easy to fix in the software to get my robot to (...) (25 years ago, 25-Jan-01, to lugnet.robotics)
