Cause for Corrosive Action

Getting to gate 4, our group has had some issues. We try to work together to overcome these issues so our grades will not be affected. The members that work well together have decided to get most of the gate done before the due date. We are no longer waiting until the last minute which is improving our grade since we have extra time to look over things or ask questions. We are getting together on a regular basis and we do not leave until we have finished what we wanted to get done or if we know what our responsibilities are to finish. Most of the group members communicate frequently about the projects to see what has been done and what else needs to be done. If a member will not have enough time to finish their part then another member will help them out. For example, one group member was struggling to finish the three design revisions so another came up with an idea and helped get it done on time.

Design Revisions

Add a battery powered motor to put energy into the spring instead of the hand operated cocking mechanism. This will make the gun easier to play with. Younger children and children with complications will be able to play with this nerf gun because it will only require them to pull the trigger to release the disc. There will no longer be a need for the outer cocking mechanism. This will be done inside the gun. The only thing the user will have to do now is turn on the battery by a switch. Once the switch is on, the gun will automatically reload and set the disc every time.
