This post is about the second day with robots.
I’ll start saying the formula of the error:
Error% = Distance (measured) – Distance (Lab view)
Distance (measured) + Distance (Lab view) X 100%
First thing we had to do, is to calculate the circumference of the wheel. (C= Pi * d)
We figured out that it was 5.5 cm and what is the same, 0.055m
Circumference = Pi * 0.055 = 0.173
Trial 1:
In both wheels the strength was the same (left & right) were 525 degrees.
The distance was 0.249.
We noticed that the left wheel didn’t have the same strength than the other wheel, making our robot goes a little to the left.
We tried this, with the same variables, three times, and we found out that there weren’t any error.
Trial 2:
We decided to change the power in the two wheels, but in a different amount, trying to make the robot going straight. (The left at 504 degrees and the right wheel at 511 degrees).
Number of wheels turned =1.4
Distance = 0.24
Velocity = 0.24
Time Traveled = 1 second
After testing this trial we found an error percentage of approximately 1.5%
Trial 3
We decided to chang the power in both wheel. (The power in the left wheel, 87, and the right one, 80).
Number of wheels turned = 1.67
Distance = 0.289
Velocity = 0.289
Time Traveled = 1 second
Error:
0.295-0.290
0.295 + 0.290/2 X 100% = 1.7%
-By increasing the power in the wheels the number of wheels turned, distance, velocity, and rotation increase.
