In Project Collisions, I am creating a system to deliverSwitch Game cards by drones. The drone will release the package from a height up to 10 meters and my job as an engineer is to develop a solution so that the package is protected in its fall.
For Drop 0, a package with the dimensions of Width 10.5cm height of 17cm and a length of 1 cm was dropped from a height of 5 meters. Below is a photograph of the package:
The package will hold 1 through three switch games. Inside, items are organised like this:
The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.
- Reset stopwatch
- Bring package to the balcony for drop
- clear area of people
- plug the computer to force plate
- Start the recording of the force plate
- start the videos
- make sure the package is 40 cm off the bar of the balcony
- start the stopwatch and drop at the same time
- stop stopwatch as soon as the package hits the ground
- stop videos
- measure the distance from the middle of the force plate to the center of the box within a 30cm radius
- get the package and bring it to a safe place
- get the videos of the Ipads
- record the force and stopwatch time in the data table
A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was ok in dropping because it hit the side of the force plate. As a project metric for accuracy, we want our project to Hit some where in a 60 cm squared box with the center of the force plate being the very middle of the box.
The average force on impact was 172N . As a project metric, our group has decided toTry and reduce the impact by at least 50%
Summary: Project Metrics
Our team has decided that the three most important criteria to design towards are ____________________<input project metrics> Below, each metric is described and the goals were determined by data from Drop 0.
- Reduce the force by 86N.
We want to make the box safe with the products clean.
Our group is now building the first prototype. I hope that we will be successful in dropping the box.
