Today, March 24th, we had a meeting with everyone. Ashwin and Cassie chose to start off by building a prototype for our conveyor belt with cups ideas.
Conveyor belt with cups idea:
-cloth for the belt
-two paper towel rolls for the shafts to turn the belt.
-three different sized yoghurt cups and cardboard strips to attach to the cloth (by making slits into the cloth).
Ashwin continued this idea by wrapping twine around the tubes to make it turn the cloth. That didn't work!
Anisha also tried to continue this idea by cutting many cardboard tubes in half to make them a sort of half pipe. She was planning on attaching many to the cloth as well as around the tubes so that it would be like treads. Anisha didn't continue with this idea because none of us knew how to continue..
Also, Matthew and Cassie continued with our prototype from last weekend. Looks at the pictures and you'll probably understand it. We had four strings, two to move the scooper and then two more to move the whole scooper back and forth to get the sand into the hole at the end of the collecting area.
At the same time Anisha and Ashwin worked on another idea that would go with the collecting device that was just discussed before. Anisha came up with an idea to make a kind of rake inside of scooper. The rake is made up of two dowels pushing or pulling a slanted piece of poster board. We all agree that we like the dowels better because they are stronger and more stable and someone can push OR pull the sand collector.
We couldn't think of anything else to do with these prototypes so we moved on to doing something with Ashwin's brother's bike. We jumped right into taking apart the bike to figure out it works! As we were taking apart the different parts, we learned a whole lot about bike mechanics and how we would want to put it back together! We have lots of ideas for next meeting after seeing and looking very closely at the bike and how we would want to adapt it to fit to this challenge. We ended up taking off both wheels, the seat, some of the gears, brakes, handles, and a whole bunch of screws and bolts!
