Remote Commands

Remote commands

Generality

All commands described below use the TCP/IP Dashboard server protocol to remote control the robot. Every command returns a CommandResponse object that describes the success of the request.

For more information about Dashboard server protocol, see : https://www.universal-robots.com/articles/ur/dashboard-server-cb-series-port-29999/

Members of Dashboard.CommandResponse :
public class CommandResponse {
 
    // A message that described the error or the action done
    public string Message
 
    // The command as succeeded
    public bool Succeed
 
    // A human readable answer
    public override string ToString()
}

In particular, for request that have a returned value, a CommandResponse<t> object is returned with an additional public T Value member that contains the returned value.

Connect to the robot

By default, the Connect function of the UR class activates the Dashboard protocol.

// Create a new robot instance
var robot = new UR();


// Setup connection to the robot
var param = new ConnectParameters();
param.IP = "192.168.0.1";


// Optional : dashboard server is enabled by default in ConnectParameters
param.Dashboard.Enable = true;


//...


// Access all commands
robot.Dashboard.PowerOn();
robot.Dashboard.ReleaseBrake();
robot.Dashboard.Play();


//...


// Close connection to the robot
robot.Dashboard.Disable();

It is possible to create a client Dashboard outside an instance of UR. To do this, you just need to instantiate a DashboardClient object

// Create a dashboard client alone, outside any UR instance
var client = new DashboardClient();


// Set robot IP
client.Enable("192.168.0.1");


//...


// Access all commands
client.PowerOn();
client.ReleaseBrake();
client.Play();


//...


// Close connection to the robot
client.Disable();

Try it with the Windows example
