Create
:
Ask the user for a size and then create a new robot of that given size. At any given
time there is a
currently active
robot (the one to which the “Walk,” “Speed,” and
“Reset” commands apply).
Walk
:
Ask the user for a number of steps, then walk the robot that many steps in the direc-
tion it is facing with its joints moving in a way so that the walk is reasonably close
to a human's walk.
Speed
:
Ask the user for a new speed that is a function of the distance between positions at
which the robot is displayed.
Reset
:
Resets the robot to its initial configuration.
Select
:
Let the user specify another robot to be the currently active one.
4.13.2 Robot walking along path
Extend project 4.13.1 by associating a path to each robot along which it walks. For example,
the robot in Figure 4.27(b) is walking along path
C
. The default path for a robot (if the user
did not explicitly define one) is a straight line in the direction the robot is pointing.
The menu should now look like
