50Find Home SequenceMoves the picker to a
known "home" position. This test assumes
nothing about the state of the mechanics. The
"home" location is the lower left position of the
box. The servo system is initialized to the "home"
location. It then automatically runs Test 51.
Runs the portion of the mechanism recalibration
related to the optical sensors. It measures sensor
offsets and calculates picker tilt and droop. This
test assumes that the mechanics and servo
system are functional.
