 # Multi Roomba Rover
 
 a remake of my RoombaRover project with a decentralized and embedded approach
+supports multiple roombas
 
 on each roomba:
-- an esp32
+- a raspberry pi zero 2 w
-  - a level shifter
+  - a raspberry pi camera
-  - DONT FORGET THE BRC PIN PULSE
+- roomba's serial port hooked up to the built in serial port on the raspberry pi
-- a power supply
-- an openIPC camera
-  - USB wifi card
-  - microphone
-  - speaker
-- MAYBE a master relay which can be turned off programatically to save the roomba from discharging. based on battery voltage plus urgent battery #?
 
-UDP:
+pi provisioning:
-one control stream out to the esp32
+- enable serial port
-one raw data sensor stream in form the esp32
+- disable wifi powersave
+- disable bluetooth

-## esp32 firmware
+## multi roomba rover
-- hooked up to the roomba's UART on pins 16 and 17
-- pin 5 is connected to the roomba's BRC pin
-  - pulse the BRC pin low for 1 second every minute to keep the roomba awake
-- connect to wifi
-- connect to the server
-- get a full frame of sensor group 100 from the roomba every 500ms
-  - send it to the server over the sensor UDP stream
-- listen to the server's control UDP stream (per roomba) and do the following accordingly:
-  - set wheel speeds
-  - seek dock
-  - enable OI
-  - safe mode
-  - full mode
-  - play song
-  - load song
 
-## esp32 -> server communication
+a website where people can control multiple irobot create 2 robots in real time 100% responsively
-- one UDP stream to the esp32 for controlling the roomba
+with a raspberry pi zero 2 W on each roomba, along with a raspberry pi camera
-  - might look like this:
+a central nodejs control server will tell the raspberry pis what to do with the roomba
-    - left wheel speed
-    - right wheel speed
-    - OI mode
-    - seek dock?
-  - blasts out at a constant rate from the server for each roomba
-  - the esp32 will listen, and follow the latest command that it sees
-- one UDP stream from the esp32 to the server for sending sensor data frames and other telemetry
-  - one full frame of sensor data per datagram
-  - send raw sensor data, the server will decode it
-  - add other telemetry from the esp32, like signal strength, etc. 
-  - maybe use this stream as a sign that the esp32 is still running healthily?
 
-## nodejs server
+## the pi side (roomba side)
-- KISS
-- decode the sensor data from each roomba
-- can support multiple roombas connected from the ground up
-- keep it simple, worry about getting the esp32 firmware right.
-  - but the server DOES have to exist for testing
-- IS the web server, hosts an entire static folder for the web UI
 
-## server -> web UI communication
-- socket.io
-- don't do anything fancy with the socket.io setup
-  - it works fine out of the box, we will optimize it later
 
-## the web UI
-- KISS
-- plain old html. no styling even. just bare minimum for testing
-- what it needs to do:
-  - allow user to select the roomba from a list
-  - make the selected roomba drive with WASD
-  - have buttons to set the OI mode, and tell the roomba to dock
-  - show a plain list of the sensor data from the selected roomba
 
-### general javascript programming guidelines (applies to the web UI too)
-- everything ES6
-  - one entrypoint file in the web UI
-- everything modular
-- everything easy to read, understand, and work on
-- comment where you think is best to describe whats going on
-
-## closing notes
-- keep the user input path (web UI -> server -> roomba) as light and responsive as possible. responsiveness is key for this.
-- responsiveness is the name of the game. The future of this program is teleoperation over the internet, with a camera on each roomba. keyboard inputs from the user must be near instant.
-- on the esp32 firmware side of things, sensor data is second priority to having a responsive control system
-  - but sensor data DOES have to exist.
-- the future of this project will involve assigning one roomba to a user, make the server able to do that from the ground up.
