Hello all!
Jeremy updating the blog for this week.
At the start of this week we finalised the different concepts that we were going to use. At the same time each member presented his chosen concept and would be proceeding with it.

By the way this is the end of week 6. The end draws near....

First off we have Angus,

Based on calculations, he has determined the number of motors needed for different propeller blades.

                                          Figure 26. Propeller configuration

From this he is also able to select the number of battery and capacity required. More calculations coming his way to take into account drag.

Next up is Bing Zhi.

He will be conducting experiments to calculate the amount of bending a carbon fibre rod can take.

                                          Figure 27. deflection equations

He is also looking into possible work of increasing the drag of the quadcopter during free fall. Very interesting work going on.

And next we have Edwin.

He has designed a test sample to simulate a load on the structure of the main piece.

                                          Figure 28. Test rig for central structure

The part was 3D printed and its use to test the force the joints can withstand before failure.

Next up we have JD,

He will working closely with Angus to complete the design of experiment for the motor selection.
He is also doing work on the microcontroller board, the arduino leonardo. We'll be posting snippets of the coding soon.

On my side I have started on the docking bay design.

And lastly we have Leonard.

                                         Figure 30. Rolling terrestrial drive

This drawing is an initial form and it will be converted into a cad drawing.

That's all for this week! Feel free to comment below.
