Mission Hub set includes three motors and a sound
and light module.
It's easy to build, has a relatively small
footprint, yet towers over
three feet tall. What do the motors do? One runs
an elevator, which
carries the included figure of Lieutenant Denver
(left). The yellow
controller has a three position switch (purple) to
run the elevator up,
down or off. A light above the elevator also

purple sound and light module is also shown in the
What do the other two motors do? One runs an arm
(yellow) that sort of
grabs the rocket. The other turns the launch pad
(right). Both of these
seem rather odd uses for the motors, but the
elevator is very well
done, and if you used pieces from this kit to
build your own creations,
you'd have some outstanding motors, sounds, and
lights. This set, which
dates from 2000, is branded "Learning Curve", and

Each of the sets also builds something else. The

afterthought dreamed up so the set could be billed
as a construction
kit, rather than just a Mission Hub kit. The five
minute project turned
into five hours. One thing that made it so
difficult was that many
parts look alike in the construction plans, and
it's not very clear how
they go together.
Remember that the great thing about the Mission
Hub is the motorized
vertical elevator. Here it becomes a horizontal
traveling crane to
position and launch a sub. It's still the best
part of the set. The
countdown voice is the same (the purple module),
so you launch the sub.
The second motor operates a claw that can move up
and down to grab the
sub. But it can't pick up the sub because the claw
opens as it lifts.
The third motor is put to better use than in the
Mission Hub, however,
as a rotating launching platform.

chamber that came with the Will Robinson figure
released with the Lost
in Space movie in 1988 (see Lost in Space
section). But we think it
looks like a sub, and it fits the claw well. The
claw can grasp it, but
not lift it, because the jaws of the claw open
when it raises. We put
layers of fluffy "snow" under the sub to raise it
up, so the claw could

Activated Robot Building Kit was branded as a
Radio Shack Exclusive and
sold in 2001. However, it still displays the
Learning Curve Robotix
logo. Inside was the Learning Curve manual,
which referred to their (no
longer active) web site. The set shown was
labelled for age 8 up, but
the robot shown is harder to build than the
Mission Hub, which was
labelled for age 9 up. The reason is the unclear
directions, a number
of similar, easily-confused parts, and a very
odd design which makes
the robot walk.
There's also an extra piece of paper shoved in the
box of building
hints, apparently meant to address this issue.

robot towering over
five feet high.

do things stand? A glance at the R&T web site
reveals a "complete
library of Robotix parts". However, they are all the
white/ black/ red/
gray parts from the Milton Bradley era. They do sell
complete kits. In
2014, the Mission Hub was priced at $174.99, and the
Ion Centurion at
$169.99. Robot Commander is $399.99.
However, the Learning Curve era, (brightly colored)
kits carry this
disclaimer: "In order to give our consumer customers
clients the very best Robotix value and keep our
shipping costs from
rising, this item will only be available in a bulk
parts bag with the
exact same parts reproduced." If I had to hazard a
guess, I'd say this
means they don't have the Learning Curve boxes or
can't use them
because of copyright reasons. Since the Robot
Commander dates from the
MB era, he carries no such disclaimer.
Anyone interested in exploring the wonderful Robotix
sets need not
despair. There are twenty years of excellent sets
from both the MB and
LC eras widely and inexpensively available on E-Bay,
used on Amazon, at
garage sales, and elsewhere, as well as oodles of
random parts to build
these or your own creations.
