The purpose of this project was to design and
build a mechatronic device. We decided to build a quadcopter
that could be used for photography. A quadcopter is stable
during flight and has the ability to perform Vertical Take Off
and Landing (VTOL) making it possible to fly almost anywhere.
For these reasons it is an ideal tool for awesome camera shots.
How it Works?
Quadcopters usually come in 2
configurations, the X configuration and the + configuration.
In each configuration, the quad achieves its motion by varying
the speed of each of the 4 motors, connected on arms attached to
a main body. Figure 1 shows the motion of an x
configuration quad. Figure 2 shows the motion of a +
The quadcopter receives a manual input from
the pilot using the remote transmitter. The signal is received
by the receiver and is sent to the flight control board. The
flight control board decides how much power each motor should
receive and regulates the speed of the motor using the
electronic speed controller (esc). Figure 3 is a block
diagram of this procedure. Figure 4 shows the power
distribution for the quadcopter.
The following is a list of all
the components required to build the drone:
·Frame: Wood and Acrylic.
The first prototype was made of mostly wood with some acrylic
giving it a strong rigid body. This frame was too heavy so for
a second prototype a laser cut acrylic one was used.
Motors: 800kv DC brushless motors were used
because they provide low speed and high torque which is ideal to
have stable flight.
Electronic Speed Controllers (ESC): 20A. These
ESCs were recommended to be used with the motors.
(10x4.5in). These propellers were selected because they were
light, cheap and large enough to provide the minimum thrust for
·Flight Control Board: KK
2.15. This board was selected because it was preprogrammed and
had an on board LCD with buttons which means that adjustments
could be made on the fly.
Radio Transmitter and Receiver: Hobby King 6
channel 2.4GHz. This combination was selected because it was
cheap. Another benefit is that it has 6 channels when the
quadcopter only requires 4. This allows for the other 2
channels to be used for accessories later on.
Battery: 5200mAh 4S
14.8V This battery was selected because it is powerful and
ensures a longer flight time.
