Today Kirby and I were supposed to put a light sensor on our robot. We put the sensor on, but it was to close to the table so we raised it up. We were the first group to attach the light sensor. We held Tigger on different colored surfaces to find different light sensor value percentages. When we found theses percentages, we used them to find the trigger point value. The trigger point is (40%+66%)/2 which equals 53%. With the trigger point value, my partner and I are going to try and get our robot to follow a black line.

I took a screen shot of what our robot accomplished. All that we and our robot accomplished was half of the figure eight. Almost every time we programmed our robot, it would not do what we asked it to do when we ran it. We also could not get the turns right. After we tried to fix each turn, they would all either be too wide or not wide enough!

Today my partner and I attempted to do a figure eight. Every time, our robots turns were either too wide or not wide enough. We finally fixed its turns, then right when we started to record our work, the robot messed up and its turn was bad! Next time we are going to try to make the other half of the figure 8

Today we programed Tigger to do a figure eight. The first run, Tigger wasn't even close to making a figure eight, it looked like he was having a seizure. Next try, his turn was too wide so we had to lessen his turn. Then, Tigger would not program, we had to get the teacher to come make Tigger feel better. We shut down the program, reopened it, then everything was better. On the last try, Tigger's turn was not big enough, so he kept running into the blocks making the figure eight.

Today we made Tigger go forward then backwards 50 cm. We were successful with that. Then we tried to make Tigger go forwards 50 cm, turn, then go back 50 cm, except our turns were too big and we couldn't figure out how to make the turns smaller. Also, Tigger's wires kept getting in the way of his wheels, and would block him from moving. Kirby and I tied his wires so he wouldn't be blocked anymore. Next time we are going to try and master a figure eight so we can have free time on Friday! :)
