MEGAKOPTER| SCIENCE NEWS
Megakopter is a RC-multirotor, commonly known as a drone. It is built at the Institute for informatics at University of Oslo by students.
The Megakopter is constructed of aluminum, plywood and a 3d-printed top cone. It has only electronics used in RC-hobby applications. This includes motors, batteries, electronic speed controllers(ESC’s) and flightcontroller (KK2).
CONTROLLING THE MEGAKOPTER
It is controlled by a pilot with a radio transmitter (TX) and the Megakopter has a radio receiver (RX). This setup is known as RC.
The KK2 is a flightcontroller, this is a microcontroller that takes the input signals from the RX and converts them to signals the ESC can process. The flightcontroller also has accellerometer and a gyro. These components makes the Megakopter stabilize.
The ESC takes control signals from the flightcontroller and feeds just enough current from the batteries so the motors spin at just the right speed. The motors spin at around 10k rpm. and when the motors combined generates 70k watts of power the Megakopter is capable of lifting the weight of a human.
To ensure safety we have installed two radio systems on the megakopter, one for controll, and one to switch of the power to the flight controller. If the flight controller stops sending signals the ESC will shut down and the drone will fall to the ground.
Our RPAS and operation manual dictates that max liftoff weight is 149.9 kg.
We have also done a drop test to ensure that the Megakopter does not break if it falls or that something unforseen happens.
