ROBOTICS FAQs

ROBO LT Beginner Set


Can programs be stored on the ROBO LT controller?

No, the ROBO LT controller can only be operated in online mode (USB connection to PC).

Can the ROBO LT controller be operated without a connection to the PC (download mode)?

No, the ROBO LT controller can only be operated in online mode (USB connection to PC).

Can the ROBO LT controller be controlled with the ROBOPro software?

Yes, that works. The ROBO interface must be set as COM/USB interface.

Can the TXT or TX controller be controlled with the ROBOPro Light software?

No. ROBOPro Light software is exclusively for the LT Controller and as of version 4.3.1 also for the BT Smart controller.

ROBOPro


What are the system requirements for ROBOunderPro?

ROBOPro 4.2.x with the TXT controller under Windows/Mac/Linux Windows:

The current ROBOPro version runs under Windows 7, 8 and 10.

Mac:

On Mac OS X, ROBOPro can be installed using the commercial program "CrossOver" and with the open source software "WineBottler" (http://winebottler.kronenberg.org/). No additional drivers are required for the TXT controller and all interfaces (Bluetooth, USB, WLAN) are supported.
Alternatively, ROBOPro can be used when it is installed in a Windows virtual machine. In this case, USB and WLAN are supported. Please note that you need a fully-fledged Windows license.

Linux:

With the help of the program wine (https://www.winehq.org/) ROBOPro can also be installed on Linux. For this, the following command must be executed on the console: 

msiexec -i Setup.exe.
No additional drivers are required for the TXT controller and all interfaces (Bluetooth, USB, WLAN) are supported. Ubuntu 14.04 LTS and OpenSuse 13.2 distributions were tested.

The ROBOTICS software ROBOPro does not operate correctly.

Please download the latest software version (update) under the heading Service/Downloads.

The USB driver cannot be installed - no connection to the controller can be established.

As of ROBOPro version 3.1.2, the USB driver is pre-installed and operates automatically when the TXT/TX controller is connected to the USB interface. You can download the manual here.

Error message "An unexpected situation has occurred" appears with the ROBOTICS software ROBOPro.

There is a software or programming error. Please send the program that causes the error message with a short explanation by e-mail to fischertechnik (info@fischertechnik.de). We're here to help!

I cannot update my TX controller’s firmware.

Start ROBOPro from the Windows start menu and not from the fischertechnik ROBOTICS terminal. Then the firmware update works without problems.

Error message "No interface to USB could be found" appears with the ROBOTICS software ROBO Pro.

Is there a power failure?
Please check whether the display on the ROBO TXT or TX controller is working or the light-emitting diode on the ROBO interface is lit.

Is the TXT/TX controller or the ROBO interface correctly connected to the computer?
Please carry out a visual inspection.

Is the USB driver installed correctly?
For the driver, see "C:\ Program Files (x86)\ROBOPro\USB Driver Installation."

Does the ROBOPro software offer a random function?

The subroutine library "Random" contains several subroutines that can be used to generate random numbers.

Where can I get a manual for C programming a ROBO interface or a TXT/TX controller?

You can download the manual for C programming under the heading Service/Downloads/ROBOTICS.

I cannot install the USB driver. I always receive an error message.

The USB driver can only be installed by a user who has administrator rights on the PC.

How can one access multiple TXT/TX controllers in ROBOPro?

You will find corresponding information in chapter 7 "Controlling Multiple Interfaces" in the ROBOPro Help. The following error messages could appear: "The minimum number of processes is too small. Please increase the maximum number of processes in the Properties window of the main program."

In the ROBOPro program's "Properties" tab, the minimum number of processes must be higher than the number of "green traffic lights" that you use in your program.

Is there a software manual for the ROBOPro software?

The ROBOPro software contains a help file, in which the programming language is explained in detail. It also contains numerous examples. In addition, all the programming elements are explained. This can be opened via the menu bar under "Help -> Help." On the ROBOPro CD this help is available as a printable PDF file, which you can download.

Where can I find the digital booklets for the ROBOTICS kits?

The digital booklets for TXT Automation Robots, TXT ElectroPneumatic and TXT Explorer are installed together with the software ROBOPro on the computer. After installation, these are available via the menu items "Windows Start-All Programs."  

The didactic accompanying material for the TXT Discovery Set is also installed together with the software ROBOPro on the PC and can be selected via the ROBOTICS terminal, which also shows the welcome movie. 

Compared to a printed version, the digital guidance material offers numerous advantages:
Under "First Steps," an animated movie shows exactly step-by-step how the controller is put into operation and how to create the first program.

The "TXT Discovery Set" contains information about components, programming the models and troubleshooting. For each model, there is a direct link to a sample program in ROBOPro. The accompanying material is also linked directly to ROBOPro's help file, so that you can jump directly to the help desk at the right places for further detailed information. 

All didactic accompanying information is available on our eLearning portal at:
www.fischertechnik-elearning.com. However, the linking of other external data (ROBOPro software, ROBOPro help, sample programs) does not work with these pdf files. To do this, the pdf files must be installed on the computer together with the ROBOPro software.

The didactic accompanying materials cannot be opened.

It could be because "Adobe Acrobat Reader" is not installed on the computer. This is available for free download at http://www.adobe.com/de/products/reader.html.
 
Note: Other readers may not support all the convenient features (such as links to other files, animations) used in the accompanying materials.

TXT/TX Controller

How can I measure the battery voltage with the TXT/TX controller?

Connect the battery to the TXT/TX controller's universal input (I1-I8). In this case, you must connect the battery’s negative pole to the input ground socket and connect the battery's positive terminal with the other input jack.

What is the maximum voltage allowed to operate the TX /TX controller without causing damage?

9V. We recommend the power supply with the fischertechnik Accu Set or Power Set.

Can the sound module be connected to the ROBOTICS TXT/TX controller?

Yes, connect the TXT/TX controller and the sound module to a common power source (important). Then connect a sound input A - B - C to one of the ROBO TXT/TX controller's outputs (O1 - O8).

What is the conversion rate for analog channels?

An internal time clock of 10ms is used in ROBOPro. This means that a program gets a new analog value every 10ms.

How can I determine that the Robo Interface has detected the connected I/O extension?

You can see that only the green "Ext" light-emitting diode flashes.

How many expansion modules can I connect to the ROBO interface?

The ROBO interface can control a maximum of three I/O extension modules.

Why do I need the ROBO TXT/TX controller for the ROBO TXT Automation Robot?

The ROBO TXT Automation Robots are equipped with two encoder motors, which send fast counting pulses to the TXT/TX controller. The ROBO interface does not have fast counter inputs that can process these signals. Therefore, you need the ROBO TX or the TXT controller.

Suddenly the TXT/TX controller inputs no longer work in my ROBOPro program.

In the ROBOPro toolbar,you have mistakenly switched the programming environment from TXT/TX to ROBOIF. If you switch this environment back to TXT/TX by mouse click, the inputs are read correctly again. 

Upon updating the ROBOPro TXT controller the error message occurs: "Error Update Phase 2 (oder 3).“ What should I do?

In this case something went wrong with the update. First of all, you can try to download the update repair tool (link to the download area) from our website and run it as described there. If the update still does not work, you must send the TXT controller to us for repair. 

My TXT controller no longer boots. What can I do?

Unfortunately in this case, you must send the TXT controller to us for repair.
