| Reliability | Time | Efficiency | Innovative | total |
Pneumatic | 2 | 3 | 4 | 3 | 12 |
Tree Design (magnets) | 1 | 2 | 3 | 4 | 10 |
Spring | 3 | 1 | 1 | 1 | 6 |
Photosensors | 2 | 4 | 2 | 2 | 10 |
Because the pneumatics scored the worst, we tried to use as little as possible. The spring was extremely innovative, and required no power, only that it needed to be calibrated. The photo sensors worked well, but only when the marbles were opaque in nature. We decided to scrap magnets altogether because the spring would take care of the metal marbles.
Good job breaking out some of your key considerations with this matrix.
ReplyDeleteBased on your commentary, I'm assuming low scores are better?
I did enjoy seeing your spring solution in action. That was a new technique for me to see.
