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

Confirm the position using 'Enter'.

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

When the lower arm (with horizontal upper
arm) has been set as perpendicular as
possible to the base plate, terminate 
this section using 'Ctrl-Enter'.
