  • Beta version of the MIT App Inventor VirtualBox Appliance file

    Hello Folks,

    We have setup a separate download page where a beta (pre-release) version of the FTC MIT App Inventor VirtualBox appliance. You can access this download page for the beta software at the following address,

    http://frc-events.usfirst.org/FTCImages/2016/beta

    There is a readme.txt file on the beta download page that summarizes the major changes to this newest version of the code. Users are welcome to try the beta software, but they should keep in mind that it is a beta (pre-release version).

    Note that if a user wants to test the new beta MIT App Inventor appliance file, he/she must make sure that they use the most current beta version of the FTC Driver Station app. The beta MIT App Inventor download page allows the user to download the beta FTC DriverStation app as a .apk file. Once the file has been downloaded to the phone, a user can side load it onto their phone.

    On the beta FTC MIT App Inventor download page, there is a button entitled "Driver Station" that will download the newest (beta) FTC Driver Station app.

    Note that we would like to start implementing regularly scheduled code releases of the FTC software, but at the moment, we do not have a scheduled release date for this particular release candidate.

    Thanks Tom.

    Are you recommending that teams move to the Beta release now, or stick with the previous one?

      Hi Cheer4FTC,

      At the moment, I do not have a strong recommendation to do either. If a team feels comfortable with the existing release (v 1.25) then they are welcome to continue to keep on using it. However, there are some changes/fixes incorporate in the beta that were implemented with the goal of enhanced reliability, so teams might want to test the new software and see if it seems to work well for their application.

      If you check out the readme file, you can see a summary of the changes (including several fixes and some changes that are designed the system a little more reliable) that were implemented in this beta release candidate.

        Thanks for the response, Tom.

        All previous releases have been new releases that superseded the previous one (I think?). Is there a reason that this particular release is a beta? Are there specific concerns you have that teams should be on the lookout for?

          What is the license for App Inventor? If permitting, can a App Inventor only download be provided by FIRST (of course, with the notice that this is for advanced uses only)?

            Hi Cheer4FTC,

            We don't have specific concerns about the beta release. We just wanted to establish a more formal release procedure. I personally like the idea of having a beta branch that provides the option for teams to test the new appliance but allows them to revert to the previous release if they prefer.

              Using App Inventor - both Virtual Box, and online versions.

              Tom, I've setup the MIT App Inventor 2 (http://ai2.appinventor.mit.edu/, for access from my workstation for programming the FTC applications, but from this website, I don't see the User Interfaces for the First Tech Challenge in the palette, as shown on the following website (http://ftc.edu.intelitek.com/).

              Also, following the instructions here, I don't have enough information to setup the Oracle VirtualBox, and it doesn't even follow the screens shown in the instructions. I know this sort of probably jumps around on different subjects, but I'm having problems with both options. I'm going to continue to look for assistance, but just lost at this time.

                App Inventor 2 from MIT, doesn't contain the FTC specific code,;only a Hosted Version designed for FTC (i.e. https://appinventor.mustangrobotics.club), or the VirtualBox Image contains the source for running the FTC robots.

                The VirtualBox image is fairly is easy to setup. Download VirtualBox (https://www.virtualbox.org/wiki/Downloads), install it, open it, click File | Import Appliance... | Select the OVA file you downloaded, follow the rest of the instruction on screen, then start it.

                  Thanks for the link to the mustangrobotics.club.
                  I got the VirtualBox image working on my old laptop, after a few miscues. The one website, http://ftc.edu.intelitek.com/, is difficult to follow, but finally got it working. The issue is I can't get it working on my primary desktop workstation, keep getting a network error. Fortunately, I think the hosted version will work currently. I'm mostly in the learning model, trying to get this understood for my high school group.
