Well, that is a thoroughly good reason to want to investigate something!
In other areas of engineering, they use magnets to attach things like
measurement
devices to machine tools and rather than use electromagnets which consume
power continuously, they used permanent magnets. The "trick" is they use more
than one, and the arrangment is set up so that a lever is used to move one
magnet
close to another to nullify its effect temporarily. Normally, these devices
are in
fact manually operated, relying on a small lever sticking out one side to
move one
of the magnets. An interesting project for the RCX would be to build a
motorized
"magnetic switch" of this general design, so that the RCX would only use
battery
power switching between states rather than all the while the magnet is on.

| (...) I have noted quite a few posts about use of electromagnets with the RCX. I have a question - what do you want to use one for? Electromagnets are about as inefficient as helicopters. They both burn energy just standing still !! If you look at (...) (23 years ago, 30-Jul-01, to lugnet.robotics)
