Motion Module- Day 2 continued

After printing out all the pieces from a delrin plastic sheet, we assembled our motion module. We quickly found that the holes for the rods in the circle pieces were too big. The middle circle piece (the one where the hole is off center) did not stay on the rod and it was very important that it would be tight enough not move in order to push the other rod upwards. It was also important for the other circles to fit in tightly with the rods because otherwise they would simply fall off. Because of that, the motion module could not work. Therefore, we changed the diameter of the new circles to .242 inches, which was the perfect dimension for the circles to stay on the rods.

After printing these parts out, we assembled our improved motion module. This is what it looked like:

With the new pieces, the motion module worked and the rotating motion was successfully transferred into a translational motion. However, the drawbridge aspect did not work as well as we expected. The bridges just fell off the circle platform that is attached to the rod that moves vertically. The problem was that the drawbridge or the platform was too small. This is a picture of what happened:
Now, we have to figure how to fix this aspect of the motion module...
