That means the
if...then
expression (or other necessary statements to determine the following
waypoint, e.g. variable waypoints) is evaluated before we actually reach
(WP_2)
which is
somewhat counter-intuitive when looking at the program sequence. If a waypoint is a stop point
and followed by conditional expressions to determine the next waypoint (e.g. the I/O command) it
is executed when the robot arm has stopped at the waypoint.

WP_1 (blend)
WP_2 (blend)

16.5:
WP_I
is the initial waypoint and there are two potential final waypoints
WP_F_1
and
WP_
F_2
, depending on a conditional expression. The conditional
if
expression is evaluated when
the robot arm enters the second blend (*).
Trajectory type combinations
It is possible to blend between all four combinations of trajectory types of
MoveJ
and
MoveL
, but
the specific combination will affect the computed blend trajectory. There are 4 possible
combinations:
1.
MoveJ
to
MoveJ
(Pure Joint space blend)
2.
MoveJ
to
MoveL
3.
MoveL
to
MoveL
(Pure Cartesian space blend)
4.
MoveL
to
MoveJ
Pure joint space blending (bullet 1) vs. pure Cartesian space blending (bullet 3) is compared in
figure
. It shows two potential paths of the tool for identical sets of waypoints.
