Robot #2

 

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.
