Requirements
Requirements
The requirements of the full sculpture draw a multitude of parallels to the mini sculpture, such as having both automated and human interface mechanical systems within a structure along with a stable build that does not drop any marbles off an intended path.
Like the mini sculpture, the full sculpture should also have at least one sensor detecting light, color, position, or velocity which would then change the output of a motor.
The major changes presented towards the full sculpture would be the requirement for the sculpture to continue "indefinitely" along with a more professional aesthetic (i.e. no tape, organized building, etc.).
It was also required to fully integrate our mini sculpture into our full sculpture.
Integration & User Interface
Integration & User Interface
For our final sculpture, we incorporated the mini sculpture we made the previous week in full. Instead of taking apart our mini sculpture and using pieces of it for our final, we used it as the base of our final sculpture. Additionally, we made sure to keep the entire track automated. Every track leads down to a point where an elevator will then lift the marbles back up to the start.
By removing the last leg of the mini sculpture and rerouting it to another elevator before returning the track to the original elevator, we were able to add a new portion of track, sensors, and motors that created a full sculpture. In this new portion, we added a track switcher that led each marble down one of two paths, either routing it through a loop or a ball dropper with a bell. Both of these tracks, as mentioned before, returned to the original elevator present in the mini sculpture, thus integrating it fully.
For our user interface, we have a button that when pressed will override a ball pusher. The ball pusher is a mechanism we created to push a ball when passed through a sensor. Our user interface overrides the sensor and activates the ball pusher manually. This is the same human interface as the mini sculpture.

Ball Pusher
This mechanism was incorporated from our original mini sculpture. It works through a light sensor that causes a motor to activate when a ball passes through. The motor will then push the ball forward onto another track using a piston design. The ball pusher is also our human interface mechanism. We added a button that overrides the light sensor and manually activates the ball pusher.
Bridge Drop
The Bridge Drop system is another device we had in the original Mini Sculpture. The mechanism operates through another piston device,and activates when a ball passes a light sensor, triggering the piston to rotate downwards, lowering the previously inclined bridge. The Bridge Drop is a completely automated system.
Track Switcher
Track Switcher
The track switcher is a new mechanism we added to the sculpture. For this part, we used another light sensor to detect a ball. When a ball passes through the sensor it causes a track to move after a delay. The delay is so the ball can go through the track before it moves to another path.
