Mini Culmination Prep- Day 6

On Tuesday, our group got together and talked about what worked well on Friday and what needed work. I wasn't there, so I was very interested to hear how it all went. After that, I helped maya a little bit with the robot. Then Lena and I tested out our notes on the lever and we perfected some of them. I think our group worked pretty well together although we didn't check in at the end, do I'm not sure how the rest of my group is feeling about the Mini Culmination

Mini Culmination Prep- Day 5

On Tuesday, Gillian and I played around with our rover the whole time. It would not go and comeback to the same place. We changed the battery, the motors, everything and we played with our program, but the rover was still being inconsistent. On tuesday in homework center, though, Bert and I problem solved. He suggested a tunnel and I decided it would be more logical to make a track/road thing. I used 5 rulers on each side and I taped them to the floor. this way, the rover can't go side to side, and it must come straight back to where it was before. It made me very happy!!

Mini Culmination Prep- Day 4

Today, Lena and I worked together again. Unfortunately, we found out that we have to launch 15 feet, not just 56 inches. This was not so great news for us. I was actually working with the rover again today, with Gillian, but Lena said that in order to make the pieces go 15 feet, we have to multiply our height measurement by 2 1/3 (2.33333) and our weight by 2. Apparently she tested this on a couple things and it worked. phew!! So, as for the rover. We got it to work perfectly!!!!!! we were so happy!! What we did, is because it turned on the way to the Mars base, we made one wheel go slower and one go faster on the way back and so it turned back and ended up in exactly the same place where it started. Yay!!!

Mini Culmination Prep- Day 3

On Friday, Lena and I took measurements of how high we had to drop the bag if we wanted certain things to go 56 inches from the board. We concluded that how high we dropped it was determined by how much surface area it had. We measured a motor, a wheel, a gray arm, 1/2 of a pincher/ grabber, a small gray connector, a 2 barred red arm, a dark gray triangular piece and a platform. We got very far. Then I helped Gillian try to get the rover to go straight be playing with the wheels and how far away they were from the body. It didn't work. We couldn't get the rover to go straight.
