Ch. 4 and 5 Robotics with the Boe-Bot

Front

What direction does the left wheel have to turn to make the Boe-Bot go forward? What direction does the right wheel have to turn?

Back

Left wheel counterclockwise, right wheel clockwise.

Front

When the Boe-Bot pivots to the left, what are the right and left wheels doing?

Back

The right wheel is turning clockwise (forward), and the left wheel is not moving.

Front

If your Boe-Bot veers slightly to the left when you are running a program to make it go straight ahead, how do you correct this?

Back

You can slow down the right wheel to correct a veer to the left.

Front

What kind of electrical connection is a whisker?

Back

A tactile switch

Front

When a whisker is pressed, what voltage occurs at the I/O pin monitoring it? What binary value will occur at the input register? Options: One (1) volt, resulting in binary one (1) at the input register.; Five (5) volts, resulting in binary five (5) at the input register.; Zero (0) volts, resulting in binary zero (0) at the input register.; Ten (10) volts, resulting in binary ten (10) at the input register.

Back

Zero (0) volts, resulting in binary zero (0) at the input register.

Front

What command is used to jump to different subroutines depending on the value of a variable?

Back

GOSUB performs the actual jump.

Front

What command is used to decide which subroutine to jump to? What are these decisions based on?

Back

The IF...THEN command is used to decide which subroutine to jump to. That decision is based on conditions, which are logical statements that evaluate to true or false.

Front

The purpose of having nested IF...THEN statements is so the program can check for one condition, and if that condition is true, it can check for another condition within the first condition.

Back

True

Front

IN7 = 1 means the right whisker is not pressed.

Back

True

Front

IN7 = 0 means the right whisker is pressed

Back

True
