prep session #5

In this prep session I made my final robotix. I took several of the elements I thought worked particularly well from other peoples robots. I also incorporated saveral things that I found worked from my "reaserch". Unfortunently since almost everyone else had already built their robots and were done I felt bad about taking parts from them so I made do with what I could still find. If I had all the parts I needed I would have used the smaller cyndrilical peices to form the main part of the arm but there were barely enough of those for what I did use them for. I also wouldhave liked to have had more hand held controllers but that was ok. In the end i think I made a fairly good arm with what I had in the alloted time period fueled by my "reaserch".

prep session #4

Most of the versions of arms that I built this session didn't work because thy weren't stable enough. In this prep session I mostly focused on playing with adjusting the center of gravity. on several different occasions I was able to adjust the center of gravity enough that the arm wouldn't fall over compleatly but it was still too heavy to be picked up by two motors. I found that the part that made most of the difference was the grabber at the end, not because it was particularly heavy but because it stuck out too far. by the end of this class I had a beter adn more compleat Idea of how my arm should work.

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.
