mini culmination

today i made a basket to go ontop of ur robot to catch the parashoot. It was really fun to make and it fits ontop of our robtot. Anja also finally got a robot to work. she was very very very VERYYYY happy. i also made a basket for my fellwo classmate em because her group didnt make her one. our group works very well together. Today we accomplished alot of things. it was really dun to have amajor breakthough the robots finally they wored. we are happy. Were doing a run through first thing tomorw.

robots

today we tried to program a robot to follow a the back line and move away from the light and go in a loop. it workd for a little while and then it got off trrack and went all over the place. its not as hard as it seems and its fun to program songs into the robot. its really hard to ake sure it stays on track though

launch pad

today clara and I were partners, we had to build a launching pad for the spaceship aka a water bottle. we have to build a structure that was light enough not to wighed down and strong enough to hold the force of 3 launches. clara and I decided to go with a triangel shape, and it held up well and passed all the tests. we realized that by making somehting not hollow it would withstand better. we also needed a whole lot of glue! we then decided if we could make something even lghted than the popcicle stick one by using skewers on teh same deisghn. the skewers also worked and they were 10 grams lighter than the first one

building report

today we had to tell eachothe rhow to build lego robots using skype. lilly wasnt very god at giving directions so me lego robot was very messed up. gabby built hers perfectly though. it took a long time and was much harder than i thought. I think this will relate to mission to mars because we wil probobly have to be communicating to eachother about what to do/program or build hen in the pods or something. it was really hard, and im not good at building.

motion detector blog

today we learned about motion detectors and graphing motion. I learned that when you speed up towards the motion detector the graph line goes down and if you move backwards it goes up. It is really hard to move and go backwards without making the graph line go crazy, you have to move really smoothly and at the same rate, and that is almost imposible. When you run faster towards or away from the detector the velocity for time is kind of like mile per hour, the faster you go, the more the graph line moves up. when you are slow the line goes slowely up, going up slower per second then when you move faster.
