Thinking Cleaner 3D

Yes I modified it to hold an Nodemcu, I have a buck step down converter for power regulating
Input voltage: DC 4.75V-23V
Output voltage: DC 1.0V-17V (Adjustable, Output < Input)

@Tim

i use an LM2596S Step-Down Module and adjust them to about 3,6V

and glued a simple plasticbox on my roomba

@xCite86
I cannot stop smiling when thinking about your roomba swirling through your flat demonstrating the pimatic logo
This is awesome ^^

@leader21

hahaha… since yesterday “he” was very proud and happy when he was cleaning my rooms… I think he was cleaning better then before

Hi

please provide more info about your modules …
if you have more info please provide
I am looking for Robot invention

Hello,
i also control the Roomba with a NodeMCU (ESP8266) using Pimatic and mqtt. In particular i am displaying the odometry position.

Hi,

I know this topic is quite old but perhaps there are some of you using the code (https://github.com/incmve/roomba-eps8266/) of @incmve.

I’m doing so and everything is working fine. Beside sending comands I also want to read the sensor data. But this is not working for my set-up. Are you reading sensor data already? Do you had problems to get it working? Can someone help me to get it working?

My Hardware consists:

• ESP8266 (WEmos D1 Mini)
• Buck step down converter for powering the ESP
• Logic level shifter for RX (https://www.amazon.de/gp/product/B00ZC6B8VM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1)

For testing I use this code down below. But I only get zeros printed out in the serial monitor even if wait some time and lift the roomba up from time to time.

#include <SoftwareSerial.h>

//* 	RX is digital pin 10 (connect to TX of other device - iRobot DB25
//	pin 2)
//* 	TX is digital pin 11 (connect to RX of other device - iRobot DB25
//	pin 1)

#define rxPin D5
#define txPin D6
#define bumpRight (sensorbytes[0] & 0x01)
#define bumpLeft  (sensorbytes[0] & 0x02)
// set up a new software serial port:
SoftwareSerial softSerial =  SoftwareSerial(rxPin, txPin);

int inByte = 0;         // incoming serial byte

/*************************************************************
  SETUP
*************************************************************/
void setup()
{
  delay(2000); // Needed to let the robot initialize

  // define pin modes for software tx, rx pins:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  pinMode(BUILTIN_LED, OUTPUT);  // set onboard LED as output
  // start the the SoftwareSerial port 57600 bps (robot’s default)
  softSerial.begin(115200); //115200

  // start hardware serial port
  Serial.begin(115200);
  Serial.println("Starting to communicate");

  softSerial.write(128); // This command starts the OI.
  softSerial.write(131); // set mode to safe (see p.7 of OI manual)
  Serial.println("Writing Values to SoftSerial");
  delay(2000);
  //softSerial.write(135); // This command starts the OI.
  //Serial.println("Start Cleaning");
}
/*************************************************************
  LOOP
*************************************************************/
void loop()
{
    softSerial.write(142);  // requests the OI to send a packet of
    // sensor data bytes
    softSerial.write(9);  // request cliff sensor value specifically
    delay(500); // poll sensor 4 times a second
    if (softSerial.available() > 0) {
      inByte = softSerial.read();
    }
    Serial.println(inByte);

  
   // checkBumpSensors();
   // delay(100);
}

I have not done anything for a while now, summertime so other hobbies

Now that it’s getting colder I started picking up on things again, I converted the old code to MQTT.
I have not tested it yet cause I had to use my ESP elsewhere
https://github.com/incmve/Roomba-esp8266-MQTT

I also want to get some data out of it like charging state etc.
If I have something useful I will post it.

No luck on reading the sensor data yet, haven’t figured out what I’m doing wrong yet.
I did make it play a piece of The Imperial March

Okay, nice to hear if your at home then. 😀

But the sensor reading is strange. There are so many successful reports on google. What kind of hardware do you use? I’m trying with an esp8266, wemos d1 mini pro. Perhaps this is the problem?
