Now drive the lower arm using the keys
'+' und '-' until it (more precisely:
the plane determined by the two center-
ing pins) is located perpendicularly to 
the base plate.

Confirm this position using 'Enter'.

As before, the ROB3 again drives to 
this position 'dynamically' and you 
have the possibility for correction.

When you have set the lower arm (with the 
upper arm set at below -22.5 degrees) as 
well as possible in a perpendicular position
to the base plate, terminate this section by 
pressing 'Ctrl-Enter'.
