2012/2013/2014: Quadrokopter

In the lab year 2012/2013 there were two groups due to the significantly increased demand for the participants. One group continues to work on the JACK vacuum robot.

Meanwhile, the second group started another new development: to construct and control a quadrocopter using corner profiles. 4 BLDC motors were fixed on the aluminum plates. The motors are controlled by a PWM signal that is specified via the I2C interface. A central control unit takes over the calculation of the control tasks. Remote control was used for communication.

The attached sensors mainly serve to determine the attitude of the quadrocopter. An inertial attitude sensor was used for this, which measures the linear acceleration and angular velocities. A microprocessor processes the sensor data and controls the four motors via power electronics using the control signals sent by remote control.
