It is a very simple laser cell:
2 in/output tables
1 stationary laser device in the middle of the two tables.
In each table the robot can pick two different type of parts and there are two different laser programs. The pick and drop programs for both parts are 99 percent identical.
They way I see it there are 3 zones
-
Left table
-
Right table
-
Laser area
A recovery scenario is fairly easy since there is a lot of space.
For the tables a linear move upwards is enough to always be clear and for the laser zone it would be the opposite a linear move down.
From there the robot always has a clear path to his home pos
