Drop Test Results

Drop Tests Reports


Why do we do the drop tests?

In any case where the balloon pops or the arduino dislodges from the housing, we want to make sure that the arduino does not get damaged and can be used again. Therefore, we do the drop tests to ensure that our arduino can survive a fall and in this case for testing purposes, an egg will emulate the fragility of the arduino and this will save us some money.

Drop Test 1 (Without Egg):  25 July 2014


Free Fall: The structure spiralled without control.
Damage: No aesthetic damage. Internal Foam bent a little.

Drop Test 2 (With Egg):  29 July 2014


Free Fall: The structure spiralled without control.
Damage: Egg cracked and the yolk spilled everywhere
   Satay Stick also snapped


Drop Test 3 (With Egg): 29 July 2014


Free Fall: The structure flew downwards in one direction only. The speed of the fall was slow.
Damage: Egg Cracked but did not make a huge mess
   No aesthetic damage.


Drop Test 4 (With Egg): 30 July 2014


Free Fall: The structure flew downwards with a high speed
Damage: Egg Cracked and the yolk spilled onto the styrofoam parts.  No aesthetic damage


Drop Test 5 (With Egg): 30 July 2014


Free Fall: The structure flew downwards at a reasonable speed
Damage: Egg Cracked and yolk did not splatter anywhere. However, when we lifted the               structure up, all the yolk spilled out. No Aesthetic Damage


Drop Test 6 (With Egg): 31 July 2014


Free Fall: The structure flew down at a high speed due to strong winds.
Damage: No damage at all. No aesthetic damage as well.


Drop Test 7 (With Egg): 31 July 2014


Free Fall: The structure flew down at a reasonable speed.
Damage: Egg Cracked and yolk spilled everywhere. The foam pieces were stained with yolk and thus, we needed to wash the foam pieces with water. The foam pieces became a lot softer than before.


Drop Test 8 (With Egg): 31 July 2014


Free Fall: The structure spiralled without control.
Damage: The egg cracked.


Drop Test 9 (Without Egg): 1 August 2014


Free Fall: The structure spiralled without control.
Damage: No aesthetic damage.


Drop Test 10 (Without Egg): 1 August 2014


Free Fall: The structure flew downwards at a high speed even when a parachute was attached.
Damage: One piece of foam from the base came off.

AND THAT MARKS THE END OF OUR DROP TESTS

Conclusion:


We realised that a parachute is extremely important in our design as it reduces the speed of flight. We also noticed that there were a few successful drop tests when foam was used. The first few tests were using styrofoam.
