Hi, All.
I'm having a problem with a rotation sensor and I was wondering if somebody
already solved that.
I have 2 rotation sensors. One of them works fine. The other one works well
as a sensor but the rotating axle has considerable friction. Since I usually
gear it down for precision, the torque generated by this friction is
"amplified" and is causing some trouble. For example, if I use a clutch gear
it usually slips.
Is there anyway I can solve that without disassembling the rotating sensor?
I thought about lubrification but I'm afraid to damage it. Could this
friction reduce with time due to usage?

| Are you sure it is the sensor itself? We have found that the axis is often "off" a bit from canonical LEGO spacing, and if built into a structure, binds quite a bit. But if you assemble it so that the body (blue) of the sensor can "float" with (...) (22 years ago, 26-Jun-02, to lugnet.robotics)
