Hello @anon62377786 ,

can you provide further intel about your setup and program used? From the information you have provided it is not quite clear to me what you are trying to do.

I use Python urx to control ur5e robot, but there will be the error I mentioned above. Is it a version problem? Do you know why? thank you!

## This is my program

import urx  
import logging

if **name** == “ **main** ”:  
logging.basicConfig(level=logging.WARN)

```
rob = urx.Robot("172.16.17.6")
#rob = urx.Robot("localhost")
# rob.set_tcp((0,0,0,0,0,0))
rob.set_tcp((-0.145,-0.302,0.055,0.261,3.112,-0.027))

rob.set_payload(0.5, (0,0,0))
try:
    l = 0.05
    v = 0.05
    a = 0.3
    pose = rob.getl()
    print("robot tcp is at: ", pose)
    print("absolute move in base coordinate ")
    pose[2] += l
    rob.movel(pose, acc=a, vel=v)
    print("relative move in base coordinate ")
    rob.translate((0, 0, -l), acc=a, vel=v)
    print("relative move back and forth in tool coordinate")
    rob.translate_tool((0, 0, -l), acc=a, vel=v)
    rob.translate_tool((0, 0, l), acc=a, vel=v)
finally:
    rob.close()

```
