Is it possible to enable and disable for example the color tracking check box in the camera control in ARC via the SDK while conected via the telnet server?
Thanks
If you have a program that you would like to communicate to ARC - you can do so with commands sent over the selected TCP port. You will have to put the ARC Connection Server into Script Mode. You can do that by pressing the Config Button on the Connection Control.
The Script Mode will allow the incoming connections on the selected port. You can now send EZ-Script commands to the Script Mode Server's TCP Port.
For what you're asking - you can send the ControlCommand() syntax. Reference the EZ-Script manual to obtain the appropriate syntax for your question.
Hope that helps!
I am pretty new to EZB and C# and haven't coded in ages.
Is the Method:EZ_B.TCPClient.WriteLine(System.String) method the correct method to use to send the string?
I can post the code if that would help.
Thanks
Thanks
You can send and receive variables and commands through TCP, I have it set up on Jarvis to do so. Your other application can use all of the control commands or anything within EZ-Script. If you wanted to send a variable to ARC you just need to send the code
in whichever language you are using to transmit via TCP.Code:
To send the other way (ARC to Application) switch it around so
Code:
Where "variable" is the external applications variable name and "$x" is the ARC variable.
You could also use HTTPGet to pull data from other applications, web pages and sites or execute web based applications.
What I am trying to do is this:
1. Read a value into my own APP from another application (This is working)
2. Send that value from my own APP using an EZ-SDK built-in method if possible to the TCP server and store it in a variable so I can use it inside EZ-Script.
Perhaps I need to phrase the question in a better way.
Is there a built in method in the SDK that I can use to send a Control string for example cc("Camera", CameraColorTrackingEnable) or $x = variable to the TCP server?
Thanks
I will whip up a quick little C# demo for you on connecting to ARC via script interface and post it here. But, I have to have lunch first
My App can wait, go have some lunch
I knew my connection to the TCP server was working using the EZ_B.TCPClient.Connect method to connect since I could read the response "ARC v2013.12.30.00 on TTY0" back into a c# variable in my app using the TCPCLient class and Networkstream method and I could see the connection come into the ARC debug window from the app.
I think my issue is how I am trying to send the string to the TCP server. An example would help very much indeed.

Thanks so much.
Firstly, I use the System.Net.Sockets.TcpClient instead of the EZ_B one. This is because the EZ_B one is made specifically for Shell prompts. The System.Net.Sockets.TcpClient is much more versatile for your needs.
Code:
In the connection method, I added code to allow you to specify the connection timeout. Without this code, simply using TcpClient.Connect() will timeout for 10 seconds or something ridiculous. My example allows you to specify the Timeout in the TimeSpan.FromSeconds()
Also, the TCP NoDelay will increase the transfer speed. Without NoDelay, the tcp packets will have a minimum response speed of something like 20ms - which is way too slow
Code:
Send Command will send the command and send the response to the Debug Log window.
Code:
The SendCommand() uses ClearInputBuffer() and ReadReponseLine(). The details are specified in their respective summary comments.
Code:
Finally, to send a command - simply send the EZ-Script syntax and voila
Code:
Based on this interaction I firmly believe I made the right choice in going with EZ-Robot in my feature robotic projects.
The fact that the EZB method is made specifically for Shell prompts at least explains why my send code did not work but my socket read did.
Thanks again.
The reason for all of this is that I am going to try and write an application that sits between the roborealm AVM navigation module and ARC. I will pull values from the module, provide them to ARC and use EZ-Script to make the robot do the movements. That way I might be able to have the robot learn a path via the webcam and then navigate it again autonomously.
Should be a nice learning experience. Now I only need the EZ-B
Just so you know your time spent on providing the information was not wasted I have successfully integrated and adjusted your code examples to pull the information I needed from Roborealm into ARC for use in EZ-Script.
Thanks again for your help
The next step requires me to having the EZB since I need to find a way to get the video from the robot's camera streamed into roborealm so the AVM module can do its job on the video stream and report back the movement variables.
Assuming I can get the whole thing working I have no issue posting what I did but don't want to get anyone's hopes up until I actually have the robot navigate using roborealm AVM navigate mode.
If you take a look at roborealm AVM you will see what it is I am trying to do especially the navigate mode.
Plus it's a nice way to learn c# even if the whole idea falls flat on its face in the end
