Part Four of the lab was to make Gizmo complete a square circuit (approx 1 meter by 1 meter) and recording the (x,y) positions of where it finally stops. This part of the lab required 10 trials. As expected, Gizmo could not perform perfectly although it still managed to do the required functions (moving straight and turning). It landed in various spots and not once back at the origin (0,0).
We computed the following results after 10 trials:
X Y
Average = 8 15.31818
Variance = 657.45 1793.914
Std Deviation = 25.64079 42.35462
Co-Variance (x and y) = -520.626
Here is an example of what the robot had to do
