When the robot cell is laid out, the equipment is generally not placed directly behind the robot, because the range of motion of many robot J1 axes is only -175 ° ~ +175 °, that is, the robot J1 axis cannot rotate 360 °, there is a blind zone of 10 °, but is there any loophole in this explanation?

Just saw an interesting video, the robot in the video can take the workpiece behind the butt, but the robot J1 axis is still ahead, and does not turn behind the butt, but rotates by the J3 axis, flipping the entire arm behind the robot's butt, this posture is not very common, it looks a little difficult, but for the robot, it is completely fine, therefore, the robot is fully capable of taking the workpiece behind the butt.

There is a 10° blind zone behind the robot J1 axis, can the robot take and place parts from behind the butt?

There is a 10° blind zone behind the robot J1 axis, can the robot take and place parts from behind the butt?

The following is the FANUC M-10iA series of robot range of motion, some models of robot J1 axis range of motion is -175 ° ~ +175 °, some are -180 ° ~ +180 °, in fact, the J1 axis range of motion can also exceed ± 180 °, like FANUC R-2000iC/165F J1 axis range of motion is ± 185 °.

There is a 10° blind zone behind the robot J1 axis, can the robot take and place parts from behind the butt?

Through the robot range diagram can be seen that the robot can cover the area behind the butt, but the area behind the butt is slightly smaller than the front, such as the M-10iA/12 robot in the figure above The front movement radius is 1420mm, and the rear is 1121mm.

Some postures, although not very elegant, are very practical, I didn't expect robots to be used like this, there is still a lot to learn abroad.
