Why is it that my robotic arm doesn’t work properly with the rmpflow tracking algorithm, what could be the reason? I am following a tutorial? The programme works fine but the effect is not the same as in the tutorial, is there any key parameter that can correct me for this problem?
I have tested the IK algorithm in parallel and it has no problem controlling the robot arm for tracking, but the rmpflow algorithm has this problem?

are you trying to move the robot base itself to a higher position like in this case table, if that is the case then the Robot articulation and the rmpflow config needs to know about the change of base of your robot prim , i think rmpflow has some function called set_robot_base_pose where you give either translation or position and orientation.

thanks for the answer, should have found the cause of the problem,it is isaacsim 4.5 exporting usd with bug.
the exported usd cannot used in rmpflow
