Again, the main goal is to know when the leg is extended, and the foot isn't
touching the ground.
So, you can mount the foot sensor so it's normally closed (pressed) except when
the foot is on the ground and mount the leg sensor so it is normally open,
except when the leg is down. Then, wire them in series (ANDed) so if they are
both closed, the leg is extended, and the foot is not touching.
Using this method, you could connect both front feet to a single sensor port.
When the port is "closed", one of the feet has a problem, and it must
stop/backup. But, the RCX can't detect if he's successfully walking, like it
can with some other methods.
