Question

Consider a program that will make your Boe-Bot navigate counter-clockwise along a circular course as shown below. Assume the diameter of the circle to be about 1 m.

In the program given below, select the values for X (P13) and Y (P12) in the PULSOUT commands that will result in the desired circular motion of the Boe-Bot.

(Select the one best answer from the choices given below.)

X = 850 and Y = 650 (Full Speed: P13 CCW, P12 CW = Forward)

X = 650 and Y = 850 (Full Speed: P13 CW, P12 CCW = Backward)

X = 850 and Y = 850 (Full Speed: P13 CCW, P12 CCW = Right rotate)

X = 650 and Y = 650 (Full Speed: P13 CW, P12 CW = Left rotate)

X = 750 and Y = 850 (P13 Stopped, P12 CCW Full speed = Pivot back left)

X = 650 and Y = 750 (P13 CW Full Speed, P12 Stopped = Pivot back right)

X = 750 and Y = 750 (P13 Stopped, P12 Stopped = Stopped) y>

X = 760 and Y = 740 (P13 CCW Slow, P12 CW Slow = Forward slow)

X = 770 and Y = 730 (P13 CCW Med, P12 CW Med = Forward medium)

X = 850 and Y = 700 (P13 CCW Full Speed, P12 CW Medium = Veer right)

X = 800 and Y = 650 (P13 CCW Medium, P12 CW Full Speed = Veer left)

a.

X = 850 and Y = 650 (Full Speed: P13 CCW, P12 CW = Forward)

b.

X = 650 and Y = 850 (Full Speed: P13 CW, P12 CCW = Backward)

c.

X = 850 and Y = 850 (Full Speed: P13 CCW, P12 CCW = Right rotate)

d.

X = 650 and Y = 650 (Full Speed: P13 CW, P12 CW = Left rotate)

e.

X = 750 and Y = 850 (P13 Stopped, P12 CCW Full speed = Pivot back left)

f.

X = 650 and Y = 750 (P13 CW Full Speed, P12 Stopped = Pivot back right)

g.

X = 750 and Y = 750 (P13 Stopped, P12 Stopped = Stopped) y>

h.

X = 760 and Y = 740 (P13 CCW Slow, P12 CW Slow = Forward slow)

i.

X = 770 and Y = 730 (P13 CCW Med, P12 CW Med = Forward medium)

j.

X = 850 and Y = 700 (P13 CCW Full Speed, P12 CW Medium = Veer right)

k.

X = 800 and Y = 650 (P13 CCW Medium, P12 CW Full Speed = Veer left)

Explanation / Answer

It should be

X = 650 and Y = 650 (Full Speed: P13 CW, P12 CW = Left rotate)

X = 650 and Y = 650 (Full Speed: P13 CW, P12 CW = Left rotate)
