A quick question for those of you that have rotation sensors- do they spin freely, or would they add significant friction to a setup? I ask because I'd like to experiment with a balancing problem, and would need to measure the angle of a pole (...) (25 years ago, 28-May-99, to lugnet.robotics)

(...) There is very little turning resistance, but then this isn't a ball-bearing shaft with lubrication. It is probably as little as you can expect from a Lego part. John A. Tamplin Traveller Information Services jat@LiveOnTheNet.COM 2104 West (...) (25 years ago, 28-May-99, to lugnet.robotics)

(...) As for using them for a balancing problem, Luis will probably want to gear up the axle at the pivot point to get a more-accurate measurement than the 1/16th rotation that the rotation sensor provides. This might add some friction on its own, (...) (25 years ago, 28-May-99, to lugnet.robotics)

I had already planned on something similar. I think (at the moment) that the additional weight will not be too subtantial, and a certain amount of friction will be beneficial, as the reaction time of the system will not be spectacularly fast, or (...) (25 years ago, 28-May-99, to lugnet.robotics)
