Steve, Here's an "all gear" based solution (minus the chain I used from the drive shaft): (URL) not sure how much gear lash is in the design I came up with, but the thing runs very well (much better than I thought it would). It's been quite some (...) (23 years ago, 4-Apr-02, to lugnet.robotics)

Hi. Can anyone help me with a problem I'm having. I'm writing a fairly simple program in NQC and when I compile I get an error saying "undefined variable SENSOR_LIGHT" The line that generates this error is simply: SetSensor(SENSOR_1, SENSOR_LIGHT); (...)

(...) OH! I see! Very clever. I guess I should explain why I wanted this thing in the first place. All the talk last week about building a Turing machine using Lego - and building primitive mechanical computers in general led me to try to build a (...) (23 years ago, 3-Apr-02, to lugnet.robotics)

(...) I've tried that - it jams periodically when the teeth of one wheel meet point-to-point against the teeth of the wheel it's driving. This seems to be because of the strange angle at which the first wheel approaches the second at it initially (...) (23 years ago, 3-Apr-02, to lugnet.robotics)
