Prep session #3

I built Two different arms today and neither of them worked. I first built an arm that bent in three places and had multiple motors at several joints. After I foun out theat theat one was two heavy I went in annother direction and built a crane which would have worked if it didn't have to be so tall. on both of these Arms the main problem was that the center of gravity was off.

Prep Session #2

I tested ut the arm I made last session and it didn't work because it was too heavy to be controlled by the hand held controllers so I tryed to connect it to the main robot, and that didn't work either. So for the rest of the session I built diffeent parts of arms to find out how I could make an arm that was long enough and light enough/strong enough at the ame time.

Preperation session #1

at our first prep session we spent most of the time coordinating and asaigning jobs. after that was all sorted out we split up into our groups and started working. me and gillian were working on the robotix section. I built an arm that had moters in several places I was unfortunently unable to test it because I ran out of time.

Launching From the Moon

Gemma, Le'Jayah, and I did the launching from the moon lab. At first we found it difficult to move the sticks and roll, but then we measured how many tiles the thing moved. It had moved 4 tiles with one balloon on and there were 16 tiles, so we needed to use 3 balloons. We tried it and it worked. After that we tried to move the ball and wheels with three balloons but one popped and we had to get more. Unfortunately that didn't work either. I wonder if It would have worked if we would have used four or five balloons or what wold have happened if we would have only used the wheels. One of us was recording the $ amount and the other two were building and blowing up balloons. This system worked very well. I think we spent about $300,000.
