Week of 3/17 -3/21

This week I started by finishing designing the cylinders and then printed them out on the new printer. I designed them so that one of them would be able to attach to the spinner through the bearing, and when I tested them it was very stable which was important. I needed them to not fall apart when they spun fast or else it could end disastrously. I tested putting it all together and it fit in the acrylic very well without falling apart or ending disastrously when I put all the pieces together, added the band, and spun the motor. Frankly speaking, it worked amazing. Then, I discovered something terrible with the bearings, something disastrous, they were magnetic. This was very bad and I was distraught at this discovery. This was until I tried testing it with no bearings, and just let it slide on the acrylic. This would work since the motor side cylinder as well as the bottom of the spinner cylinder could still have bearings since they were far enough away from the motor and the magnet.

When I made the holes I made them to fit the side of the bearing, so now they were much too large and I changed the design to make them smaller and hopefully able to fit the current design. This would help with not wasting material and also make it so it won't be as shaky. My robotics teacher also showed me some other ways such as acrylic rods that might work better or some plastic bearing but I will test this design first and if it doesn't work then I'll look into some of those options.
