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.

On July 10 we did a competition on who could make the tallest tower with paper and tape. Then when time was up, Leland and I got ours up to 63 inches, Jeyton and Kamalu’s was 4 ½ inches, and Ian and Daniel was 1 ½ inches. But the main point of it was practicing to collaborate, plan, build, and record everything in our engineering log page.
The second thing we did was make simple machines using VEX pieces. The simple machines were, lever, inclined plane, pulley, screw, pendulum, wedge, and wheel & axle. Then we had to create a machine by combining 2 of the simple machines to make our car go the furthest. We had an inclined plane with a wheel going down it, and it hits something to make a chain reaction, and the reaction makes our car go forward. Kamalu’s and Daniel’s was a really tall inclined plane, then a seesaw; the wheel went down the inclined plane, hit the seesaw; then the seesaw hit the car to boost the car. It was 2-1 other team’s way. Even though we got it farther. We went farther but we were a few seconds later.
Then we coded on Virtual World and I got to mission 9 on Palm Island. There are 9 missions in total on Palm Island. And they get harder as you go.

Day 2 of practice, we learned part names of the VexIQ pieces. One of the parts we learned was called a “Worm Bracket”. Maybe it’s called a “worm” bracket because it has worm sized holes.
I learned how to program a virtual robot in Graphical RobotC. We coded Palm Island “missions” with a “Mammalbot” I don’t know why it’s called a “mammal” bot. Maybe it’s as fast as a mammal. Maybe a Giraffe. But probably not. Because Giraffes aren’t that fast. Maybe a cheetah.
Then we did our Robotics Bio. We had to write about what skills we brought to the team and what you are looking forward to.
We learned about what an engineering log is and how we are supposed to write entries in it.

sDay 1 of practice, we learned about the Manoa School Robotics Program. We learned the expectations for participating in the competitive teams. The expectations are we should be respectful; no rude comments, no bullying, and no backtalk. We learned about grit and made grit posters so when we feel frustrated, we would look at the posters and it would motivate us to keep trying. Grit basically means to never give up. We also learned routines like signing in when we arrive and cleaning up when we leave.

Coaches note regarding expectations: Students should also try to be at every practice and be focused.
