The draft of the new frame.

I have started the construction of a new frame for the "quadcopter". In this frame the propellers, engines and components are within the frame, to prevent them becoming damaged if a crash happens. The new frame shown in the Figure in an initial state, it is made of carbon tubes (4mm in diameter) which are connected by connectors used in kites. As I could not find connectors for the corners, I did them by myself using aquarium tube. However this tube is flexible and therefore it not strong enough to be used in the new frame. So I will have to find out another way to connect the corners of the new frame.

After many accidents...

After many accidents at my home with the "quadcopter", several propellers have broken and several walls of the house scratched (my wife would like to kill me...), I have concluded that this device should not be used neither tested indoors. So I have decided to make another frame that solves this problem.

My first quadcopter.

I built this quadcopter (quadrotor) from a kit that I modified to use in my academic master's thesis. In a short resume, the objective of the thesis is to provides an adequate solution to wide area sensing by the use a mobile autonomous rotorcraft platform capable of sensing and collecting information from sensing nodes thus permitting the deployment of sensor nodes with a smaller density.
