Adjust 'mobile robot' movement timing, insert letters into '3D world' and set additional features. (Mobile robot, Misc, Text in 3d-PDF)

Hello, I’m a beginner in the VC program.
I’m writing because there’s something I can help you with.
I am using the 4.9 version of the program.

Here are the parts that need help.
I also share the file I have made so far, so I would appreciate it if you could refer to it.

  1. After first pressing the ‘Play’ button, parts are accumulated on the conveyor belt connected to the ‘Feeder’, and I would like to set the mobile robot to move when the accumulated parts become ‘3’. Currently, if you look at it in about 21 seconds, the mobile robot starts moving toward the conveyor belt before the accumulated parts become ‘3’.

  2. As shown in the attached photo, can I put the information of ‘input’ and ‘output’ on the bottom of the parts ①, ②, and ③ in writing and reflect the contents in real time?

To give you a little bit more detail,

  • In part ①, write feed mode, interval, etc. on the floor and change the number of interval parts written on the floor to change the speed at which parts come out of the feeder in real time.
  • Part ② and ③ are written to go up in real time while the contents of how many parts are stacked are ‘Play’.

I think the text insertion on the floor is 'Misc’→ ‘Text In 3D-PDF’, is it correct? If it is correct, I would like to know how to reflect it in real time in the ‘play’ part if I change the content on the writing on the floor.
