DobotRPC 4.6.0

Dobotlink communication module

This version is relevant for Dobotlink 5.0.0

DobotRPC is a dobotlink communication module based on websocket and JSON-RPC . It provides python ports to communicate with dobotlink and allows developers to communicate with the GUI. Here is a more detailed list of the package contents:

• The file contains both RPCClient and RPCServer files that users can call upon their own needs
• DobotlinkAdapter: The adapter module is used to adapt to the new set of interfaces

Utils

• Loggers: Loggers information

Examples

• Users can communicate synchronously or asynchronously.The asynchronous mode is as follows:

::

# Async demo
from DobotRPC import DobotlinkAdapter, RPCClient, loggers
# The asyncio module provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives.
import asyncio


# Coroutines function
async def main(dobotlink_async):
    # Display information with Dobotlink
    await dobotlink_async.api.ShowMessage(title="Async Demo Message",
                                        message="Async Demo is running.")

    # Search for available ports
    res = await dobotlink_async.Magician.SearchDobot()

    # Get ports
    if len(res) < 1:
        return
    port_name = res[0]["portName"]

    # Connect
    await dobotlink_async.Magician.ConnectDobot(portName=port_name)

    # PTP
    await dobotlink_async.Magician.SetPTPCmd(portName=port_name,
                                            ptpMode=0,
                                            x=230,
                                            y=50,
                                            z=0,
                                            r=20)
    # Disconnect
    await dobotlink_async.Magician.DisconnectDobot(portName=port_name,
                                                queueStop=True,
                                                queueClear=True)


if __name__ == "__main__":

    loggers.set_level(loggers.DEBUG)
    # Get the Eventloop reference
    loop = asyncio.get_event_loop()
    # Initializes, connects to dobotlink, and is executed before the Loop runs
    dobotlink_async = DobotlinkAdapter(RPCClient(loop=loop), is_sync=False)
    # Perform coroutines
    loop.run_until_complete(main(dobotlink_async))

• The synchronization mode is as follows:

::

# Sync Demo
from DobotRPC import RPCClient, DobotlinkAdapter, loggers


def main(dobotlink_sync):
    # Display information with Dobotlink
    dobotlink_sync.api.ShowMessage(title="Sync Demo Message",
                                message="Sync Demo is running.")

    # Search for available ports
    res = dobotlink_sync.Magician.SearchDobot()

    # Get ports
    if len(res) < 1:
        return
    port_name = res[0]["portName"]

    # Connect
    dobotlink_sync.Magician.ConnectDobot(portName=port_name)

    # PTP
    dobotlink_sync.Magician.SetPTPCmd(portName=port_name,
                                    ptpMode=0,
                                    x=230,
                                    y=50,
                                    z=0,
                                    r=20)

    # Disconnect
    dobotlink_sync.Magician.DisconnectDobot(portName=port_name)


if __name__ == "__main__":
    loggers.set_level(loggers.DEBUG)
    # Initialize, connect to dobotlink
    dobotlink_sync = DobotlinkAdapter(RPCClient(), is_sync=True)

    main(dobotlink_sync)
