You most likely have your axis’s inverted in code. Post that section of your code here, please.
Also, when you start a post, put your question or idea in the title or description
can I delete one program in the robot box ？ Each time when I use setting.delete program , I need to delete all . can I only delete one？
no, but you can download a new one to the same slot/position and it will delete it and add the new one
our robot is move for two motor , can I set those motor use 80 pct ？
You can use setVelocity
I am mean in the controller setting
can I set the motor to run only 80 pct, in the controller setting
Please post your code…
