Summer Session Day 4

​Today we had a test on simple machines (inclined plane, screw, pendulum, wheel & axle, pulley, lever, and wedge).

We watched 5 videos about building tips for VEX IQ robotics. Then after the videos, we drove this cool robot. But Mr. Leong took out the cables to the arms because we were having driving practice not picking stuff up practice. We did two types of driving; tank, with both levers, and arcade, with only one lever. Then after, we learned about two ways to make the wheels move. The first one was gears, and the other one was sprockets & chains. We also looked at robots from like 2013-2019. The first ones (2014-2016) about 80% of the robots had gears but then as they got to 2017-2019 most of them had chains. The gear drives have more friction, so sprockets & chains is better, I think. So anyway, we got into two groups 1 group (Me, Kamalu, and Jeyton) made gears drive. And the other group (Liana and Paige) made Sprockets and Chains drive. We finished our drive and tested it out. It worked. But the problem with it was that it looked like a small valley. In other words, it was tilted. So to fix it we put two 2 x 12 beams under for support and it looked better.

After that, we practiced driving around the VEX IQ Squared Away game field with our drives.
