Rasptank servo mix up/operation??

1590741547

After much trial and tribulation, i finally got my rasptank working, now i am wondering why the servos are responding as they are.
i pluged the servos 11 and 12 in the way the instruction show, but the arm up/down controls movesthe camera modual  and there is no way to move the part of the arm between the hand and the upper arm.

Alo, on the moter controls, the up arrow moves the tank backwards and the down arrow moves it forwards. the left and right arrows move it the way it indicates.

the hand left and right and jaw servos work as they should

any help would be greatly appricated
Thanks
Jim

change：
Dir_forward = 0
Dir_backward = 1

into:
Dir_forward = 1
Dir_backward = 0
If it can operate normally after modification, it may be that the two servos that cannot operate normally have been installed upside down.
eg: Modify file operation: run "sudo nano adeept_rasptank/server/move.py" in Raspberry Pi
Find the place need to modify
After the modification is completed, confirm the modification with"Ctrl + x", "y", "Enter"
