FSM Rotating Stage

A rotating stage for Theather Art Department

Features are:

• sectors on the stage are determined during the stage setup
  • the possible divisions are 2,3 and 4 sectors
  • sectors are numbered clockwisely and referenced to the electrical motor's starting point/position
  • should dynamically create FSM states based on the number of stage divisions
• it is possible to rotate in all directions
• stage is maually controlled or synced with time and events garnered from the play scripts
• finds shortest path to the sector of choice
• two halfs of curtains are controlled in sync with the stage
• stage rotations are done to align/limit the view of the audience to a sector with the aid of the curtains
• rotation value is linked to the number of divisions and a 0 degree reference point
• motor to be used should be able to orient itself in space, i.e be able to know its angular position at any given time

Connecting from the FSM app to the Blender app

The process of achieving this is detailed here: https://gist.github.com/DraTeots/e0c669608466470baa6c.

Linux Server

Create virtual ports

• socat -d -d pty,rawer,echo=0 pty,rawer,echo=0

Connect network port to (virtual) serial port

• ser2net -d -C "7778:telnet:0:/dev/pts/2:115200 8DATABITS NONE 1STOPBIT remctl"

The other port is connected to the serial code of the app

Linux Client

Create virtual ports

• socat -d -d pty,rawer,echo=0 pty,rawer,echo=0

Connect one of the serial ports to the network port

• socat /dev/pts/2,b115200,raw,echo=0 TCP:10.147.19.112:7778

The other port is connected to the serial code of the app

STDIO to PTY or TCP

• socat STDIO /dev/pts/3,raw,echo=0,crlf
• socat STDIO TCP4:localhost:7778

Create a network between the server and the client using zerotier
