(...) The problem seems to me that the power to run the machine comes only from the logic inputs. Thus, you'll have to push insanely hard on a one bit input in order for it to operate any reasonable amount of logic. Maybe you need motorized (...) (20 years ago, 14-Mar-04, to lugnet.robotics)

(...) That definately is a problem, after a couple of gates it grinds to a halt - a mixture of the slippage between gears and the problem you have identified. I had envisaged that I could use a piston arrangement to drive the clock signal backwards (...) (20 years ago, 14-Mar-04, to lugnet.technic)

I'm not much on Boolean calculations -- if it stops part way through, does that make it a MAYBE gate? Jim "Martin Howard" <goldfishwbp@yahoo.com> wrote in message news:HuL5rn.4vq@lugnet.com... (...) halt - a (...) signal (...) logic (...) shift (...) (20 years ago, 15-Mar-04, to lugnet.technic)

Hi: I am sorry if this is a repeat question. Did anyone successfully stabilize the Legway using standard Lego light sensors ? Any links or proofs, code, etc ? Thanks Barry (20 years ago, 16-Mar-04, to lugnet.robotics)

(...) I recall someone put a pair of light sensors out on the end of very long arms out in front and back of the robot. This meant that they moved a much larger distance than if they were mounted close to the wheels so that their relative lack of (...) (20 years ago, 16-Mar-04, to lugnet.robotics)

Salut Philippe, hi everybody, (...) a Lejos version. The hardware is the same with two sensors, and the program is loosely based on yours. Tweaking was not easy, but with a little luck the program below now manages to stand on a sheet of white paper (...) (20 years ago, 17-Mar-04, to lugnet.robotics, lugnet.robotics.rcx.java)

Bonjour Jürgen, (...) I just tried LejWay, it works fine! (it was also the opportunity to install Lejos under BricxCC. Works great too...). The behaviour is somewhat different from BrickOS version, less shaky but it falls if tilt angle is too high. (...) (20 years ago, 17-Mar-04, to lugnet.robotics)

Hi Philippe, (...) nice to hear, for me it didn't work any more when it was darker. I would like to have some automatic calibration of the parameters to be more robust w.r.t. conditions, but I guess that is difficult. (...) Yes, probably one could (...) (20 years ago, 18-Mar-04, to lugnet.robotics)
