  • Remote TCP/USB control through WebRTC

    3drobert03/02/2024 at 16:28 0 comments

    Remote control (client-device)

    The server can control multiple client devices by P2P (camera, TCP/USB device)

    Control multiple USB/TCP devices in the distance.
    Create a RTC_Host using RTC_Host_App and connect to it through RTC_Client_App.
    Then connect some TCP/USB device to mobile where RTC_Client_App is running and prepare the desired responses to the received commands from TCP/USB device.
    Customize this responses with the value to receive from RTC_Host_App.
    RTC_Host_App will detect the available commands for the control of TCP/USB device connected to RTC_Client_App and will put a control interface like switchs, potenciometers or a joystick.
    RTC_Host_App can activate the RTC_Client_App camera too.

    Web version:

    Remote control (server-device)

    Multiple clients can control the server by P2P (camera, TCP/USB device)

    USB devices connected to single RTC_Host_App can be handled by multiple RTC_Client_App.
    From RTC_Host_App the number of players with device access allowed in a single round and when next round should be triggered can be configured.
    Clients can view the scene with the server webcam.

  • Robot controlled by WebRTC (PC-mobile)

    Robot controlled by WebRTC from PC (4G router) to mobile device. Is not under wifi. I can to controll this from kilometers.
    Mobile communicate with MCU by USB or ESP8266 (to have the mobile connected to a power bank)
    Using a free TURN server to avoid CGNAT in both (Robot & PC).

  • remote control by WebRTC

    3drobert03/26/2023 at 07:42 0 comments

    I maked remote control for the vehicle using WebRTC.

    I have a website hosted in Glitch where I've running NodeJS+WebRTC.

    First user that enter in website application acts as WebRTC server and this have controls to drive the client vehicle.

    JETSON in vehicle has connected a WIFI adapter and this adapter is connected to mobile ISP data.

    When Jetson verify for internet connection opens Chromium and load the Glitch website as second user (client). Then it make P2P pair with server, share webcam connected to Jetson and then active WebUSB to communicate Chromium with the microchip MCU by USB.

    Server can previsualize the client webcam and send commands to it by WebRTC DataChannel.

    Now the vehicle has the following functions:

    - Automated drive by detecnet pursuing silhouettes.

    - Short distance remote control by two ESP8266 modules (Access point in remote controll and Station in vehicle)

    - Long distance remote control by WebRTC and the ISP data.

    Now I need to see how I going to attach batteries (which I don't have) :)

    If some day we are confined again (I hope that doesn't happen) I will be able to see what happens in the street xDDD

  • remote control ready

    3drobert02/05/2023 at 15:41 0 comments

    Remote control ready and setted to RC or USB modes only. I thinked I can drive a big vehicle sitting using remote control directly and I don't need two manual controls separately.

    vehicle quering to remote control about desired config (gearedmotor/BLDCcontroller & USB/manual/RC controll)

  • Added direction switch

    3drobert01/16/2023 at 08:33 0 comments

    Schematic changes to add direction switch. Firmware also ready but still need the RF code.


    I'm going to investigate now to create FM transmitter/receptor :D.

  • schematic for geared motor or BLDC controller

    3drobert01/15/2023 at 20:02 0 comments

    Making two modes for TCPUSB class controller. 

    Using BLDC controller for big vehicle (manual control, RF or Jetson_USB)

    or using geared motors for little vehicle (RF or Jetson_USB)

The idea of using multiple small MCUs instead of big one always was on my mind. The hardest part is to get them talk to each other.

I try to divide the work as much as possible so that the master only has to listen to the data of its associated sensor from the slaves and send it all via WIFI to the PC. And receive the action also via WIFI and indicate it to the slave that has that action associated with it.

Even one of the 3 MCUs of the slaves is just to coordinate the other two which are one MCU for the gyroscope and the other MCU for the servo. So that the information is quickly available and flows without much of a jam in making calculations when the master requests things from the slaves.
I have activated PLL to achieve 48MHz too
