Hi, I am new in this field and trying to remotely control universal robot with primary and rtde interface. I don’t need much information so we don’t want to use some big libraries or frameworks.

For primary interface code worked perfectly:

import socket

s = socket.socket(socket.AF\_INET, socket.SOCK\_STREAM)

s.connect(("_localhost"_, 30001))

s.send(movej(p[-0.175,-0.607,0.092,1.211,-1.215,1.113], a=1,v=0.25)" + “\n”.encode())

s.close()

Robot moves, but with rtde I have some problems. Code looks like this:

import socket

s = socket.socket(socket.AF\_INET, socket.SOCK\_STREAM)

s.connect(("_localhost"_, 30004))

s.send(movej( ‘get\_actual\_tcp\_pose()’".encode())

tcp = s.recv(77)

print(tcp)

s.close()

it prints empty byte object (b""), decoding it also gives empty string. I think problem is with incorrectly using socket. Please help me how to get actual data.
