In the first week of lego midstream Ariana, Sabrina, and I were partners. The goal of the activity was to 1) drive the car in a 2ft radius, one revolution 2) 2ft radius in reverse, one revolution 3) have the car make a sound. The three of us started to plug in numbers for the car to move in a clockwise rotation. To do this you must put the car at different power levels to make the car operate. When we tested the car it went ~4 ft radius forward. We did not test the car to go in reverse in a 2 ft radius because our car started to have problems. When we tried to set up the robot to the computer but ran into issues. The system on the computers was not woking correctly to operate the robot. Out of the three computers we were using the system didn’t work properly so we had to use Prof. Shatz computer. By the time we were able to program the car and make it turn class was over. We were not able to complete the class activities.

The car used to preform activity

In the second week we had another team exercise. The goal of the exercise is to measure the distance and speed the car moves. First we had to measure the diameter of the wheel of the car which was .5 cm. Then we had to find the circumference of the car.
circumference = 3.14 X diameter
c = (3.14) X (.05) = .157
The next part of the exercise is to run the car.
To find the rotation of the car the equation is
rotation = # of degrees / 360
The degrees that the wheel rotated is related to the turns of the wheels because it determines how far the robot will move. The distance is related to the number of turns because, number of turns X circumference = distance. Next, we put the car next to a ruler and observed how far the car will go at different speeds. In one second the car moved 29cm in one second and in two seconds the car moved 32cm. This activity shows that time and distance are correlated. Some discrepancies that could have occurred during the exercise are that the wheel and ruler could have not been matched up properly and data was off.
