We started off working seperatly. Jon worked on the outside part of the lander and Ty worked on the Inside part that holds the egg. We used rubber tubes and crossed them at the top and the bottom was connected to PVC pipe which made the base. 5 batteries were tapped to the base to make it land upright. This added too much weight so we took one battery off. For the inside part or the egg cage we used straws to make a box shape then closed off the bottom. First thread was used to make the basic shape to hold the egg in the box. We later added crisscossing straws on each side of the box to better hold the egg inside. After further testing we put thicker string around the thread and box to completely sucure the egg. We had put 8 hooks in the rubber tubes of the lander to connect to the egg cage. We connected it useing rubber bands and now the egg cage is susspended in the middle of the outside part of the lander. keeping the egg inside the cage had been our main problem and the crisscrossed straws and string solved this problem. After this we had serveral seccessful tests before the egg cracked. We learned from this that if we spin our lander when dropped it lands much better and the egg doesnt crack as often. After we decided that we had everything finalized we used logger pro to calculate the velocity of our lander. |
