arm.set_position(x,y,z) is not working with UArmConnectException

[quinnliu]

This problem was self fixed :)

UPDATE: running q@Q-336-MacBook-Pro:~/Documents/jia.com> uarm_helper firmware -d fixed the previous problem copied from the master branch on github

However, my arm.set_position(150, 150, 150) = False always returns False && my arm.get_position() = [nan, nan, nan] always is nan

Here is the output of all the current API functions I have called:

Is there a way for me to visit the pyuarm API for version 2.2.5.3 specifically?
