Description

LidarBot is a powerful development kit for Automated Guided Vehicles(AGVs). Comes with a 360 Lidar sensor, 4 Mecanum wheels, M5 Core, RGB Bars and a remote conroller with Joystick panel and more. With 4 Mecanum wheels, you can make it move to any direction, forward, backward, to left and to right. The Lipo Batteries enpower the Robot to run long-hours. You can display the map data, that obtained from the lidar sensor, on the screen or upload somewhere else thru Wi-Fi and program it into any format.

we have implemented Real-time communication via ESP-NOW between robot and remote, Mazing-runing , self-tracing and more. If you are interest in AGV development, We especially encourage you to modify the open source code we have offered on github and enhance it yourself.

Program analysis:

1. Main program of LidarBot:

/* Main program */
void loop()
{
  espnow.BotConnectUpdate();// ESPNOW reconnect
  lidarcar.MapDisplay();// display map
  esp_now_send(espnow.peer_addr, lidarcar.mapdata, 180);// ESPNOW sends map data
}
  • Single function resolution:

    • Usage of reading radar data

      #include "lidarcar.h"
      LidarCar lidarcar;
      
      lidarcar.Init();
      GetData();//save radar data to array distance[]
      
    • Usage of line following

      #include "rprtrack.h"
      Rprtrack rprtrack;
      
      SensorStatus();// save line following data to array sensorValue[]
      CalTrackDev();// handle array sensorValue[], get car offset and save it
      
    • Usage of ESP_NOW

      Please refer to https://github.com/m5stack/M5-espnow

2. Program of RemoteController

/* Main program */
void loop()
{
  espnow.RemoteConnectUpdate();// ESPNOW reconnect
  keyboard.GetValue();// read data of joystick
  // ESPNOW sends joystick data to car
  esp_now_send(espnow.peer_addr, keyboard.keyData, 3);
  MapDisplay();// display map
  accessport.AnalzyCommand();// send map data to PC software
}
  • Single function resolution:

    • Usage of JOYSTICK

      #include "keyboard.h"
      KeyBoard keyboard;
      
      keyboard.Init();
      // get joystick data and save to adX, adY
      GetValue();
      
    • Usage of communication with PC software

      #include "accessport.h"
      AccessPort accessport;
      
      accessport.AnalzyCommand();// send map data to PC software

Wonderful product in beautiful retail packaging. Works out of the box with pre-programmed functions such as roaming with automatic obstacle avoidance in two speed modes. The remote also works out of the box already configured to control the bot like a standard RC vehicle. A charger is not included for the remote but it can be charged via a USB-C connection. The downside to this is that the remote will power on once a USB-C cable is connected and can not be powered off without disconnecting the cable. Other than that, perfectly happy with this purchase. I’ll be implementing custom functionality into the device soon. Note: the lidar sits about 115mm off of the ground so smaller obstacles will not be detected. I recommend getting some VL53L0X distance sensors also available in the M5 stack store to deal with that.
