Bioloid Build Report
The Bioloid is a unique robot, unlike any of the other robots we have built before. The Robonova-1, KHR-1 and
the I-Sobot are designed specifically to be humanoids that walk on two legs. But the Bioloid was designed to be
more of an erector set, allowing you to construct many shapes and sizes, from a robot car on wheels to a robot
dinosaur. The humanoid shape is only one of the possibilities available with the Bioloid, but for the purposes of
this build report, we concentrate solely on the humanoid.
Our build report will demonstrate the Comprehensive Kit. Other kits are available to suit your experience level
and your budget (Beginner and Expert). As the chart below shows, it only took 7 hours to build the humanoid
shape of the Bioloid. This time measure starts with taking the parts out of the box and ends with getting the robot
to move under its own power. This is substantially faster than how long it took to build either the Robonova-1 or
the KHR-1 in our previous Build Reports.

PREPARATION:
Before you start building, you need to find a place where you can spread out and work. There are lots of small
parts included in the Bioloid kit, and it is easier to find them when they are spread out. You should also protect
your work surface against nicks and scratches by putting down some cardboard. The servos may leak a small
amount of lubricant, so be careful and protect your table.
TOOLS:
In every Build Report we do, we always recommend having the right tools for the job. The Bioloid was designed
to be assembled using a set of Japanese Industrial Standard (JIS) screwdrivers. American screwdrivers will not
work with this kit, and you run the risk of stripping screws if you try to use an American screwdriver. Do yourself
a favor and buy the right tool to get the job done.
The Bioloid Comprehensive Kit comes with all of these parts to
make many different kinds of robots. You won't need all of
these parts to build the humanoid.
After the build you can see a small amount of lubricant
from the servos has stained the cardboard.
QUICK START:
The Bioloid kit comes with a manual called "Quick Start", which is kind of ironic since the book is 200 pages
thick. This manual includes the instructions on how to build 26 different kinds of robots with the Comprehensive
Kit. The first thing you should do is put the manual away and don't bother with it. Most robot manufacturers
make the mistake of putting their instructions in a bound manual which is nearly impossible to hold open to a
specific page while assembling a robot. The best approach is to open the PDF version of the manual included
on the CD with the kit. This way you can look at the instructions on your computer screen and use both hands
to work on the robot, instead of using one hand to keep the book open to the right page. Furthermore, you can
zoom in on specific pictures in the PDF version to see details not visible in the printed manual.
The manual does have detailed diagrams of how parts are supposed to be assembled, but the instructions on
how to actually do things is pretty light. The manual doesn't have a lot of tips and warnings on things to watch
out for. You have to follow the pictures very closely since there isn't a lot of text. If you have ever built furniture
from IKEA, then you will know the feeling.
While the manual has a lot of detailed diagrams, there isn't a
lot of text describing what you need to do, and how to do it.
The nut rests in a flange on the
upper left side of the servo.
NUTS AND BOLTS:
Other robots we have built relied on screws to hold servos and frame brackets together. The Bioloid has
taken a different approach using nuts and bolts to keep things together. Considering the modular features
of the Bioloid, this is pretty logical. Unfortunately, dealing with tiny screws was bad enough on other robots,
now you have to deal with tiny nuts and bolts on the Bioloid. It can be incredibly frustrating getting these
parts to fit together properly. Your best bet is to watch the short video that comes on the CD which
demonstrates the proper way to insert and remove nuts from the servos.

TOTAL TIME TO BUILD:
Here is a high level summary of each step in the process and how long it took:
Individual Step Time Cumulative Time Step
1 hour 11 minutes 1 hours 11 minutes Build brackets for legs & feet
1 hour 23 minutes 2 hours 34 minutes Attach leg servos & connect wires
0 hours 47 minutes 3 hours 21 minutes Build both legs & feet
1 hour 38 minutes 4 hours 59 minutes Build brackets & servos for arms
0 hours 27 minutes 5 hours 26 minutes Build torso
0 hours 13 minutes 5 hours 39 minutes Attach both legs to torso
0 hours 8 minutes 5 hours 47 minutes Attach both arms to torso
0 hours 15 minutes 6 hours 02 minutes Attach head to torso
0 hours 20 minutes 6 hours 22 minutes Wire servos together
0 hours 22 minutes 6 hours 44 minutes Connect CM-5 unit to torso
NOTE: These robots are not meant for children. All of the humanoid robot models discussed on this website use
powerful servos that can pinch or even crush your fingers if you are not careful. Consult the recommended minimum
age from the manufacturer before allowing children to use any of these robots.
Use your screwdriver to apply a little
leverage and "pop" the nut into the flange.
The nut is now properly seated in the
flange, ready to accept a bolt.
