Turning
Karel can turn in place to the left whenever he's standing at a corner.
Direction sensing
Karel has an internal compass that can tell him what direction he
is facing (north, south, east, or west).
Sensing walls
Karel has three inexpensive cameras attached to his head and
can tell when there is a wall in front of him or to his
left or right.
Hearing beepers
There is an inexpensive microphone attached to Karel's head.
He can hear a beeper with this microphone, but only if he is standing
at the same corner as the beeper.
Picking up beepers and putting them down
Karel has a soundproof bag attached to his waist.
He also has a mechanical arm with which he can pick up a beeper and
deposit it in the bag, or take a beeper from the bag and place it on the
ground.
If a program is read into Karel's onboard control computer, he can carry out
the actions specified by that program.
