Rough sketches of the revolutionary moon phase model that will combine all learning styles into one incredible learning machine! It will provide visual, auditory, reading and kinesthetic learning modes. The prototype will use an NXT to power it. We plan to meet with an electrical engineer to talk about ways to reduce cost and create kits that schools could buy and use to help teachers and students get the most out of their moon phase learning.
Our team decided to break the table into 3 general zones. The south zone (zone 1), the west zone (zone 3) and the NE zone (zone 2) We started the programming in zones 1 & 3 first because they are closest to base and easiest to navigate. We are starting to work on figuring out the best way to get to the NE corner. When we get there we are hoping to get Sports and the slider.
THe carabiner is for picking up the loop on the south wall. The first version didn't have enough space for loops that were slightly different. It also stuck out too far to be able to do the Cloud Access mission in the same run. It got shortened, a thinner axle for the "gate" part, and made taller to increase the margin for error.We use the wall follower in our Engagement Zone. We use the drift steer to keep it against the south wall. It drops into the robot and pulls right off. Very easy to attach and remove. The pulley wheels that follow the wall come off sumetimes. Thinking that we should make the axles that hold them longer? Also, it wouldn't work if the table has short sides. Maybe we need to make it extend down lower too just in case.
Now that we have decided on a robot chassis, we are making a duplicate so that two subteams can work on programming the robot at the same time. This is taking a loooong time and is a lot harder than we expected!!!!Big team discussion focusing on the two chassis prototypes. Both were really cool. We went through the list of must have characteristics we decided on before building the chassis and compared how well the prototypes met these. We first decided if we wanted to start from scratch and build a completely new one combining ideas, or choose one and modify. We decided to choose Paul McFerrari Crab (not a name every one likes...) and make modifications to it. WE'll start duplicating soon.We met with Mark Samberg and learned about how the Friday Institute works hard to improve education. They have really cool meeting facilitites and do a lot to help teachers and legislators innovate what they are doing.This is our first attachment. It started as a stick of short technic beams and we were using it to open the door. It didn't always move the same way. So we changed the programming so the set up was always laying flat against the brick. This made it move the same way everytime no matter who ran the mission. Then we realized the door wasn't always exactly the same. So we added a bendy stick at the end so it was flexible. This made it more repeatable. We also figured out a way to add a loop to carry the ball. Planning to use this to make a shot toward the goal.
