QUADCOPTER The goal of presentation was to acquaint you to a semi-autonomous quadcopter capable of self-sustained flight via wireless communications while utilizing a microcontroller. The quadcopter was designed to be small enough so that costs would be minimized. which is why small motors and propellers are being used. While a PIC microcontroller, accelerometer, and gyroscope are communicating between each other to maintain control. The scheduler program arranges the following tasks: controller input, sensor data received from the accelerometer, Gyroscope, and Magnetometer. The wireless transceivers use SPI to send control signals to the microcontroller on the quadcopter from the handheld controller unit. The accelerometer/gyroscope and magnetometer both use I2C to send the amount of acceleration, stabilization, and the direction vector. The motors are being controlled by the PWM ports on the PIC microcontroller. To achieve flight, two of the motors must apply downward force and the other two motors have to apply an upward force. To turn, one pair (left or right side) of motors slows down to turn the copter. To ascend, all motors will increase in speed, and will all decrease in order to descend. To move forward, the front two motors will decrease while the back two motors will increase. And vice versa in order to move in a backwards direction. We are also working on integrating our own Graphical User Interface (GUI) which will allow us to have direct control over all systems.]]>
