The RCX / Lego Angle / Rotation sensor seems to be able to keep up to the
power of the motor that comes with RIS.
We've only made one item - windshield wipers, since getting our rotation
sensor last week
We only use the standard Lego RCX software
The first run was at power 8
In sensor watch Forward- change direction when the sensor reads 4..5
and in sensor watch reverse change direction when it reads -4..-5
In the first run the wipers were flying back and forth, and the machine would
last about 20 seconds before flying apart.
After changing the power level to 1 for a more realistic motion.
The Wipers (axle connected to another axle at 90 degrees). Roughly as
shown - please excuse the stick diagram.
