Lecture Racing. Student vs FlightPlan!

Application for students It is a unique tool for quizzes on lectures and classes. No need to prepare the quizzes ahead, you can do it in real time! The class turns into a competition, a race – who is the best?! It engages the students and makes them pay attention. How is that achieved? Everything is done on the fly, no preparation required! The teacher asks a question about the slide on a projector, and students mark their answers on the same slide on their devices. Then, the teacher encircles the correct answers using his tablet or smartphone. After that, the app analyzes the results and creates a student rating that can be transferred back to the projector or to the personal device. The students and the teacher can use various devices including tablets, smartphones, laptops, and personal computers. The system Lecture racing includes an application for students Lecture Racing.student, an application for the projector Lecture Racing.projector, and a support website http://lectureracing.com/. Features: 1) Conducting tests and quizzes on lectures and classes without preparation, in real time 2) Racing competition, who is the best?! 3) The students receive badges based on results of the tests and quizzes. The answers given faster get higher score. 4) Presentation control tools, laser pointer, and drawing 5) Conducting quizzes, analyzing answers, and presenting the results 6) Three types of student rating 7) Presentation slides can be uploaded beforehand at http://lectureracing.com/. 8) Support for presentation formats PPT, PPTX and PDF

This app allows you to visually program a flight plan for the Tello Drone and then upload it to the drone for execution. You can also fly the drone manually with the app if you wish. Real time telemetry from the drone is displayed on the glass cockpit. Tello is a mini drone equipped with a HD camera that is manufactured by Ryze Robotics and includes a flight controller with DJI smarts. We access the Tello API by connecting to the airframe via a WiFi UDP port. Once a connection is in place, the drone is controlled using simple text commands. So before using the app, make sure that your Tello drone is on and the iPhone is connected to the Tello WiFi. You can check this by going to Settings -> WiFi. The first time that you use the app it will request your permission to use Location Services. This is required to allow the app to determine the SSID of the WiFi connection so we know when you are connected to the drone. The app doesn't use location services for anything else. The app has two modes of operation: manual and planning / auto pilot. The app status is shown in the top centre panel. This panel also indicates whether WiFi is connected or not. It may take a few seconds for a change in WiFi status to be displayed.  If you are connected to the Tello and in manual mode, then tapping the take off icon will cause the drone to auto take off and hover. Tapping land will auto land. Only tap emergency stop if necessary as it will immediately stop all four motors and the drone will fall out of the sky! Tapping the plan button toggles the app state between planning mode and manual mode. In planning mode a grid (representing the ground) and yellow arrow (representing the drone), will appear. The arrow direction indicates the front of the drone. In planning mode, you can enter the sequence of commands which will be transmitted to your drone for execution. Start with take off or you will receive a warning message. When you are finished with your flight plan tap land. The arrow will simulate the position of the drone but is not to scale. Tapping the upload icon will send your flight plan to the Tello and execute it. While the plan is being flown, the app will display the glass cockpit. Real time telemetry from the drone is displayed on the glass cockpit. This includes pitch, roll, yaw, velocity (x, y, z), temperature, time of flight (tof), height, battery percentage, motor on time, barometric pressure, and acceleration (x, y, z). A full description of how the app operates is provided at our website (reefwing.com.au). FlightPlan is a refined version of another that I described in an article called "Programming the Tello Drone using Swift." (https://medium.com/@reefwing/programming-the-tello-drone-using-swift-f9122fd4aeb8?). You can refer to this article to understand how the app operates and create your own version.
