I will discuss the G15 specfically, but the
comments are the same for the KS.
The box states that this is for 10 years and up, but
I think a little more maturity may be needed, perhaps
12+. The instruction manual is a nice size and the
pictures are decent, but there is no text. For the most
part, the manual is adequate, but I hit a problem
several times with the G15 because the rendering of
the 3D pieces in 2D is sometimes ambiguous. Twice
with the G15, I had to disassemble and reassemble
some major subsystems because a piece was in
I strongly recommend watching the available
videos. When I built the KS, I watched the videos and had
only a minor problem (which was my fault). There is one
main reason to look at the manual, as well. Each screw
used in the instruction has a life-size picture of the screw.
This is a big help as some of the screws are only a 1/16 of
an inch or so different.
Construction goes quickly, and I finished the G15 in
about five hours over four days. The KS took about twice
that. I found no problems in the G15 manual, but the KS
manual omits two screws when connecting the legs. These
may be critical, but when making the robot, it is obvious
they are needed.
One final point: Many of the pieces are “polarized,”
meaning that the two sides are different (one side usually
has cutouts to hold the nuts). This can make a critical
difference if you get it wrong. The manual is adequately
clear about this.
One major difference is that the G15 requires four C
batteries (I eventually got four rechargeables), but it seems
to be pretty good on battery life. The KS comes with a
rechargeable battery pack.
Both are powered by the “Meccabrain.” This controls
the servos, motors, and lights (especially the eyes).
Currently, the Meccabrain is proprietary, but when I spoke
to them they said it would eventually be open source. This
is great news as I can see adding sensors (such as a PING)))
sonar, for example) to enhance the robot.
When powered up for the first time, the system runs
some diagnostics and — if all goes well — some
initialization. Here is where I had a problem with the G15,
However, the new brain acted just like the old, so I did
some debugging. One of the servo wires was slightly out of
the socket. When I fixed that, the robot came to life! Still,
they were very helpful and quick with replacement parts, so
I give them an A.
Once the checkout is done, it asks you for your name
and its name (Meccanoid is the default), and then goes into
listening mode. The eyes tell you what mode the robot is in:
blue represents listening for its name, green is for the main
menu, amber is for motion control, and purple is for the
Once you say the robot’s name, it goes into command
