# Multi Roomba Rover
a remake of my RoombaRover project with a decentralized and embedded approach
supports multiple roombas
on each roomba:
- an esp32
- a level shifter
- DONT FORGET THE BRC PIN PULSE
- 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 #?
- a raspberry pi zero 2 w
- a raspberry pi camera
- roomba's serial port hooked up to the built in serial port on the raspberry pi
UDP:
one control stream out to the esp32
one raw data sensor stream in form the esp32
pi provisioning:
- enable serial port
- disable wifi powersave
- disable bluetooth

## esp32 firmware
- 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
## multi roomba rover
## esp32 -> server communication
- one UDP stream to the esp32 for controlling the roomba
- might look like this:
- 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?
a website where people can control multiple irobot create 2 robots in real time 100% responsively
with a raspberry pi zero 2 W on each roomba, along with a raspberry pi camera
a central nodejs control server will tell the raspberry pis what to do with the roomba
## nodejs server
- 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
## the pi side (roomba side)
## 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.
