Today in LDD Our challenge was to make a Lego model that was robust and strong. For it to be classified a robust it had to be drop tested from table height. First I built a back up model so if my other model broke I would have that one. That model was just a normal car but it was very robust. Then I started on my next one, for that model I made a quad copter. The propellers were wheels connected to axles then the axels were connected to the base. Because my Bricks didn’t overlay it wasn’t very strong and when I tested that model it broke.
In design on Friday we worked on our Rube Goldberg machines. In our machines we had to have the number of elements and simple machines equal to the number of people in the group. Our group was almost done building but unfortunately we didn’t have enough simple machines so we had to completely restart. We all went back to our table and thought up a whole new design, this time with enough simple machines. Our design now has a pulley, inclined plane, fulcrum and a lever. The fulcrum and lever make up a see saw and the inclined plane makes a ramp. So far we have built the first element, a ramp leading to a see saw. Next session we will try to get the see saw to work and build the next element, which is a track leading to a pencil that releases a wind up car.
Today everyone chose electives. There were four to choose from, including robotics, 3d printing, micro worlds and my group Lego Digital Designer. The program that our group uses is the same as the program that the people at Lego use to make new products. Instead of using LDD we got to use actual Lego, I built a tractor and tried to make steering that worked but it was too hard. I think our group is the best.
