Today was and tomorrow will be preparation for our demos to middle school students on Thursday. Today we wrote up our power point presentations; written so that middle schoolers can understand it. Also, we further developed and began to construct our demos. Dean and I dropped the Space Elevator/Lunar Orbiter idea as the TETRIX robot, requiring a heavy 12V battery pack, would be too heavy and unwieldy to climb a rope. Instead, we decided to create an iPad controller for the other two robots, one that would ultimately control nine independent robots. For the demo, we created sample GUIs (graphical user interfaces), and Dean, who had been working on a TETRIX tank, decided we should control that tank with the iPad.
Dean: Prepare Tank for Demo. Worked on powerpoint -> wanted to work on Tank.
Lawrence: Today for my group was mainly just thinking how we can finish our robot and make it better. The whole day we pretty much spent all of our time building. Today was a fun but stressful day because with our prototype of the NASA Axel Rover was difficult to make out of Tetrix because a lot of pieces that were necessary for our prototype were not located in the Tetrix kit so we had to find ways around these conflicts. At the end of this day we had pretty much finished our prototype but the huge problem was that the wheels were not big enough for our robot. 🙁
Jess: It was on this day that I searched NASA rovers on youtube and came across the Nasa Axel Rover. It seemed pretty cool and interesting, so that was the idea we decided to take and replicate with Tetrix for the middle school audience. After doing a bit of research on the rover, we started to mock it up in a very prototypic way. This was the first time I had actually tried to build something complete out of solely Tetrix. We ran into a lot of problems with construction, mainly since the motor mounts don’t have holes the properly match up when placed perpendicular to the majority of pieces, and since the biggest wheels/gears were far too small.
Briyana: Mostly just made a power point for the middle school students.
Sarah: All that our robot did at this point was detect craters, although I hadn’t yet written a code for that to work. So Morgan gave us the idea to make (in a future version) the robot able to hold smaller robots inside of it that it could deploy at specific times. That way the middle school students could participate and create small LEGO robots to put inside of the big one.
