EXMAN TAKES ORDERS
A strange sight greeted Tom’s
and Bud’s eyes. In the first rays of sunlight,
the space robot was moving back and forth about the
laboratory in wild zigzag darts and lunges.
As he rolled toward a bench or other
object, the brain energy seemed to send out invisible
waves that knocked things over! Already the floor
was strewn with toppled lab stools, books, and broken
test tubes. The heavy thud had apparently been
caused by a falling file cabinet.
“Stop him!” Bud yelped.
Exman was heading straight for a plate-glass
window! Reaching from floor to ceiling, the glass
formed one entire wall of the laboratory.
“Oh, no!” Tom tensed,
realizing that it was hopeless to try to stop Exman
in time.
But an instant later, the rolling
robot stopped of its own accord, as if registering
the fact that its energy waves were now striking a
fragile surface. The thick pane of glass vibrated
in its frame.
“Good grief!” Tom wiped
his brow. “Let’s corral that thing
before he wrecks the whole lab!”
Exman was already rolling off on a
new tack. The two boys managed to grab him before
more harm was done. The brain energy in its container
seemed to calm under their touch.
“What in the name of space science
triggered it off?” Bud wondered out loud.
“Time. It must have reacted
to the passage of time,” Tom conjectured.
“I suppose it just decided to explore this place.”
He added a bit nervously, “The sooner we can
communicate with this energy, the better!”
“But how?” Bud asked.
Tom’s brow furrowed. “Say,
I wonder if Exman might understand a direct order?”
Tom backed a few paces away from the
space robot, then said in a loud, clear voice, “Come
here!”
Exman remained fixed to its spot.
“Move right!” No response. “Move
left!” Still no response.
“Guess you’re not getting through, skipper,”
Bud commented with a grin.
“No,” Tom agreed.
“I can’t predict what kind of energy this
brain will respond to. Being only energy, it
must respond to other energy and sound is our form
of energy. The problem is the same as with radio
waves, which are also energy. We must figure
out how we can vary the energy, so it can transmit
information to Exman.”
“What do we try?” Bud asked.
“Or is it hopeless?”
“I’ll try communicating
with it via the electronic brain, which I have adapted
to fit this problem.”
The boys cleaned up the wreckage caused
by Exman in his dawn venturings. Then Tom went
by jeep to the computer laboratory, made connections
to his electronic brain, and wired it for remote control.
Then he returned to the private laboratory. There
Bud watched as he hooked up the leads from the computer
to a transmitting-receiving decoder with a short-range
antenna.
“Speak, O Master!” Bud
said, imitating a squeaky robot voice. “Sound
off loud and clear!”
Tom grinned and tapped out a command
on the keyboard: Move backward.
Exman rolled backward! Bud gave a whoop of delight.
Tom signaled: Move forward. Obediently
Exman rolled toward him.
Stop. Exman stopped.
“Hey, how about that?”
Bud exclaimed happily. “It really savvies
those electronic brain impulses!”
“And minds them—which is equally
important,” Tom added.
A moment later the brain energy seemed
to become impatient. It spurted off in its wheeled
container toward a laboratory workbench.
Crash! A rack of test tubes
went sailing to the floor with an explosion of tinkling
glass.
Stop! Tom signaled frantically.
Again Exman obeyed the order.
“It’s like a mischievous kid,” Bud
said.
Almost as if in defiance, Exman scooted
off in another direction. Then it stopped abruptly
and swiveled around, one of its antenna arms knocking
a Bunsen burner to the floor as it did so.
Come here! Tom signaled.
As the culprit approached, he added sternly, Stop
where you are. And stay there until you receive
further orders.
This time Exman stood patiently, awaiting
the next signal. Bud got a brush and dustpan,
and the boys cleaned up the broken test tubes and
replaced the burner on its shelf.
Then Tom began feeding more complicated
instructions to Exman through the electronic brain.
He guided him through a number of dancelike movements
and other drills, and got him to send out a wave of
heat which the boys could instantly feel. Tom
was even able to make the robot aim its wave energy
so as to short-circuit a switch on an electrical control
panel.
Tom was both pleased and excited.
“Bud,” he exclaimed, “the brain reacts
as quickly as that of a highly intelligent being!
Just imagine—without any sort of decoding
equipment, it can pick up and understand the
radio signals I beam out to it!”
“What we need now,” Tom
went on, “is a simple language to get our ideas
across to Exman without having to use the electronic
brain all the time. That means I must find a
way to give Exman senses as we humans have—smell,
touch, sight, hearing, taste. Then it could receive
the same reactions we do and talk directly to us!”
“Sounds like quite an order,”
Bud said wryly. “Speaking of which, how
about us phoning Chow an order for breakfast?”
He did so, and a short time later
Chow wheeled a food cart into the laboratory.
As he dished out man-sized helpings of ham and eggs,
the cook kept a wary eye on Exman. Tom was putting
the robot through a few more lively maneuvers.
“A good meal’d calm down
Ole Think Box,” Chow observed grumpily.
“But what do you feed that there kind o’
contraption?”
“Well, not gum, that’s
for sure!” Bud teased. After tasting his
first forkful of food, he gasped, “And none
of this ham!”
Jumping up from his lab stool, Bud
began whirling, dancing around, and flapping his arms
as if he were burning up.
“Help! Help!” he
yelled. “Chow’s poisoned me—just
like he did Exman!”
Chow’s leathery old face paled
under its desert tan. “Great snakes, Tom!”
the Texan gulped. “Have I really pizened
him? Maybe we should call Doc Simpson!”
Doc was the medic in charge of the Enterprises infirmary.
Tom was unable to keep a straight
face. “Better call someone with a strait
jacket—or a butterfly net!” he said,
quaking with laughter. “I’m afraid
he’s just pulling your leg, Chow!”
Chow’s jaw clamped shut like
a bear trap and he glared at the pirouetting young
flier. Bud collapsed on his stool, doubled over
with mirth.
“Sorry, old-timer,” he gasped. “I
just couldn’t resist!”
“Okay, Buddy boy,” Chow
said darkly. “And mebbe I won’t be
able to resist gettin’ even one o’ these
days!” The cook stumped out of the laboratory
in his high-heeled cowboy boots, a picture of outraged
dignity.
“Better watch out, pal!”
Tom warned with a grin. “Just remember:
it’s never smart to bite the hand that feeds
you!”
“I guess you’re right,”
Bud agreed, wiping away the tears of laughter.
“I’ll remember, just as long as Chow promises
not to serve us any more armadillo soup or rattlesnake
salad!”
Chow’s fondness for experimenting
with weird dishes was a standing joke around Enterprises.
The boys ate their meal hungrily.
As they were finishing, Tom glanced at the big clock
on the wall. It was now well past eight o’clock.
“Wonder why Dad hasn’t
come to the lab,” he remarked. “I’d
better call and find out if he’s all right.”
Tom picked up the telephone and asked
the operator for the direct line to the Swifts’
home. His father answered.
“’Morning, Dad!”
Tom greeted him. “I thought after your call
last night, you’d be over bright and early to
see our visitor. He’s already—”
“What are you talking about,
son?” Mr. Swift broke in. “I didn’t
phone you last night!”
