Communication concept with robot needed

Hi,

I am looking to connect a mobile device (smartphone) with a / any robot (ABB, UR, FANUG, ...).



I need a professional that can make a concept how to send data from the smartphone to the robot and from the robot to the smartphone, given the following strings:

- USB, WiFi or Network cable allowed for data transfer

- direct communication from smartphone to roboter and way back without intermediate server

- if possible don't us a PLC (unless it is the own of the robot)

- data send is a few ASCII characters both ways

- protocols must be open source or commercially available for the smartphone and robot

- if possible don't use OPC/UA



Deliverables:

- concept how to connect a smartphone with a robot

- components that need to be purchased (incl. source)

- protocols used / documentation

- wiring scheme or technical drawing



Not in the scope:

- programming (robot and smartphone)
