The main parachute was tilted to one side. As an effect, it did not help the lander land on its feet. What worked was the parachute slowed the fall of the lander. So, it did half of its job.
The mini parachutes were not placed correctly so, it did not balance each other out. Hence, the lander leaned to one side. We did not have time to calculate the position and place it properly because we did not have much time to make the lander.
The parachute connectors were connected to the moving cardboard instead of the main cup. Causing the parachute to be moving when we threw the lander off the building. Another issue might be those connectors were bendable. We should have used less bendable ones because it would have allowed the parachute to be positioned properly.
We tried to get the Lander to land on its feet because it was supposed to help break the lander's fall. Unfortunately, it did not get to be used because the parachutes did not make it land on its feet. Even though we did not get to test it, we were pretty confident if the lander landed correctly, the feet would have worked.
