1. PRODUCT INFORMATION ROPE DANCER
The Rope Dancer is a robot which can climb over a rope. Then it looks like if
he is dancing because of the movements of the rope. However, before this
robot can climb you have to build it first.
An excellent robot kit for beginners. This battery-controlled kit teaches the
basic principles of robotic mechanics and motion. This simple robot can be
assembled by almost anyone from age 8 and up. Only basic hand tools are
required for the assembly. We already included a screwdriver and a wrench
in this kit.
This robot kit is more than just fun. Assembling, building and following instructions help develop fine motor skills, hand-eye coordination and understanding
technical drawings.
Specifications:
Power source : 3V (2 Penlite AAA Batteries 1.5V, not included)
Current consumption : Approx. 100 mA max.
Height : 140 mm
Length : 170 mm
Width : 85 mm
Warning
- No return is possible after having opened the bags with components and pieces
- Prior to the assembly, read the manual thoroughly.
- Be careful when using tools.
- Keep this kit away from young children during construction and operation.
(They might get hurt by the tools or swallow small components).
- Observe the correct polarity of the batteries.
- Keep the batteries dry. When the Rope Dancer gets wet, remove the batteries and let
the Rope Dancer dry for some time.
- Remove the batteries when you will not use the Rope Dancer for a longer period.
- Children below 14 should only assemble this product with the help of adults.
- Use new batteries and do not MIX batteries (old, new, recharchable) in any way!

2. GENERAL ASSEMBLY INFORMATION
IMPORTANT: First read all the instructions about the mechanics !
Follow the step-by-step instructions for the mechanical assembly as shown in this
manual. Read and work very accurately, this is the best way to avoid assembly failures.
When you follow the instructions and study the drawings and comments carefully, you
have a big chance the robot will work directly and without any problems.
Also a great help is the picture on the package. You can see very clearly how the robot
should look like. Best is that you only take out the parts from the packages and frames
the moment you need them! Sometimes parts or bags are numbered.
All parts fit perfectly so you do not need to use force assembling this robot!
Do not hurry and once more, best is to read all instructions first before you actually start
the assembly.
Small plastic Hammer
The correct tools already
do half of the job!
Screwdriverset
Always use a good fitting screwdriver size
Hobby knife
WARNING! Be carefull not to cut yourself
when using a hobby knife!
How to cut the plastic parts
Assembly of a gear to an ax
When you install a gear or a pinion to an ax or shaft, like the pinion
to the motor shaft, you must be very careful. Be 100% sure you
put the right gear onto the right ax. Best way is always to press the
gear on the shaft with your hands. When you cannot manage it
this way, use a very small plastic hammer. When you use a hammer, you can protect the gear or the shaft by putting a piece of
wood or carton between the hammer and the part you will hit on.

Plier set with cutting plier &
flatnose plier
Best plier size is approx. 150 mm.
To take out the plastic parts from a
frame, use a sharp hobby knife or a
cutting plier. Cut carefully and take
of the bosses with a knife to make it
smooth.
Do not cut parts from a frame
when you do not need them
directly!
Locknut
English
Self-tapping screws (Parker)
A self-tapping screw looks similar to a wood screw.
When you screw it in a hole, it cuts the threads at
the same time. Never try to screw it down all the
way for a first time, because it may easily become
stuck or you will damage its head.
Tapping screws always have a sharp point,
sometimes with a small carve. They look
almost the same as screws which we use for
wood, only the thread is more fine. The best
way is to screw it in and out a bit.
Do not screw a tapping screw in and out too often because the screw hole may become enlarged and
the screw will loose all grip and proper function.
Screws and nuts
Thickness
Length
1. Screw in
2. Screw out a bit
3. Screw in further and continue
step 1 and 2
Nut
In a moving environment, screws and nuts must be tightened properly. A lock nut is a
special nut with nylon inside which will lock itself automatically.
Another easy way to lock a screw is to use ordinary fingernail polish. A big advantage
of nail polish is that you always can loosen it quite easily again. A professional way to
lock a screw is to use for example locktite, a sort of glue especially made for screws,
but it is very difficult to unlock such a screw afterwards.
The size of a screw is expressed by thickness and length. A screw with the marking M2 x 10
means 2 mm thick. The length of the thread is 10 mm. A M2 nut is used for a M2 screw, so the
nut always corresponds with the screw thickness.
Wrench
This kit includes a small wrench. Please use this wrench
to fit the M2 and M3 nuts in a proper way. You can use it
instead of a plier.
