The completed Sumo Man robot
All the Movit kits include a comprehensive instruction
manual which should be followed closely during the construction
process to ensure a successful conclusion!
The
Sumo Man in kit form as removed from the box.
All the parts
are clearly laid out in relevent groups and detailed in
the comprehensive instruction manual accompanying the kit.
Individual parts should not be removed until required and
care should be taken to correctly identify tapping screws,
machine screws and so on to avoid confusion during assembly.
All traces of joiners (sprue) should be removed from all
the parts.

A
motor converts electrical energy into kinetic energy. It consists
of an electromagnet and a permanent magnet, and spins by using
the power of "pull" and "resist." In the
SUMO MAN it produces the power to rotate the wheels and arms.
The rotating power of the motor is transmitted to the cranks
and the wheels by gears and shafts installed in the gearbox.
Gears function to, "change the direction of rotation,"
"change the speed of rotation" and "change
the power of rotation" in the motor at the same time.
The
gearbox has to be constructed by getting the motor, the
crown gear and the 2 flat spur gears with pinions on to
the correct base as shown in the picture. Take care with
the order you put the gears in otherwise the gears will
jam and it wont work.

The
gearbox is attached to the main panel.
Attach
the gearbox to the main panel using M3x10mm screws provided
and the 2 nuts. Make sure that the gear box is orientated
correctly (ie make sure the cranks are at the top).

The
wheels are installed on the right and left panels, then
are mounted onto the gearbox and main body. (hint: long
nose pliers are required at this stage.)
Once mounted on the body the tracks are put on. Using a
nutdriver to secure the lock nut will make life much easier
when constructing SUMO.

The
picture on the left shows you the
positioning and correct line up of the cogs.
Make sure your robot looks like this before proceeding to
the next stage.
The picture on the right is a basic overview of the
whole robot at this stage. |

The
left picture shows you where the
cranks are meant to be. The right hand picture is of where
the punching fists are meant to be.
If you have problems adding the punching fists, use a small
tapping hammer
to push the pinion on the punching fists into the cranks,
but remember to use it gently! |

On
the left
we have the battery box the terminals in the battery box
have to be installed by you, take care with this, don't
get confused with the negative and positive terminals.
On the right we have the battery box attached to
the robot. When inserting batteries, refer to page 40 in
your instruction manual for warnings on how to deal with
batteries.

Left
picture-
the motherboard, this is the main processing board this interprets
the signals from the sensors and tells the motors what to
do. You have to wire up the motherboard on your own, no soldering
is required at this stage. It is not very complicated. Follow
the guidelines carefully though.
Right picture- this is relatively simple, all that
is being done is using a self tapping screw (supplied) to
attach the motherboard to the clear plastic dome, then connect
the wires to the correct terminals in the battery box and
the motor. |
