Brief update

I’ve been busy with other projects, traveling for work, and other tasks, that have cut into my App Inventor posts. Sorry about that!

One task I have been busy with is a project from AV8 Designer LLC to create an aircraft wing tip protection system. The system places proximity sensors on the tips of aircraft wings to detect – and help prevent – collisions with obstacles during aircraft ground movement operations. Aircraft are pushed and pulled around on the ground during all times of the day and night, and during all types of weather. They are frequently squeezed into aircraft hangers and parked extremely close to other aircraft. Unfortunately, this leads to occasional wing tip collisions that are expensive to repair.

The wing tip sensors provide audio and visual alerts of potential collisions and status (with audio and visual display) on Android tablets or smart phones carried by ground crew. The Android app is simple to use but incorporates complex programming to wirelessly communicate with all wing tip sensors. The app and the wireless communication links were implemented using App Inventor, rather than the Android Java SDK.

We took a risk in choosing to use App Inventor. While preliminary experiments were done to verify the concept, we did not know if we could develop the full application in App Inventor. Well, we took the risk and everything worked out great. Using App Inventor we were able to quickly develop – and demonstrate – the user interface and functionality. In doing this project, we proved App Inventor is capable of creating powerful and complex industrial applications. App Inventor can do much more than only educational and gaming applications!
