This is a presentation that teaches you how to use lego technic. It first covers the basic concepts and then moves on to more complex things such as motorization. For the demonstrations I have used the Lego digital designer software. Made using Powerpoint 2016.

4. THE BASICS

5. BASIC MODEL SYSTEMS
Here, you create a working gear train. The yellow parts seen at the end are
stoppers. The stop the axle from coming off the beam. You can turn one of
the gears, and you will see that the other gear will turn too. This system
provides 1:5 reduction if you turn the small gear first, or 5:1 reduction if
you turn the big gear first.
This model is a working car.. This car cannot steer. It is more complicated
than the last model, but works just as well. You can use different colored
beams or different wheels

6. ALL ABOUT GEARS
Spur gears. These gars can be connected in a straight
line. However, if used with crown gears, they can be
connected with right angles. Available in 8, 24, and
40 tooth versions
Bevel gears. These gears can be connected in
right angles with other bevel , or double bevel
gears. Available in 20, and 12 tooth versions
Crown gears. These gears can be connected in
right angles with spur gears. Available in only a
24 tooth
Worm gears. These gears can be used with spur
gears or double bevel gears for a very high gear
reduction.
Double bevel gears. These gears can be used in
right angles or in a straight line. Available in 12, 20
and 36 tooth versions.

7. HINGE SYSTEMS
For relatively light applications,
the readymade hinge parts can
be used.
For heavy duty applications,
we use a custom hinge made
of beams. In the picture, I
have also added a gear for
controlling the movement of
the joint.
This is a universal joint which
is usually used coupled with a
hinge, which allows rotation to
be transferred over a hinge.

8. TURNTABLES
This is the Lego large turntable. It has 56 teeth
on the outside and 24 teeth on the inside. A
planetary gear system can be built by using an
8 tooth gear as the sun gear and by using two
8 tooth gears as the planetary gears
This is the small turntable which has 28
teeth. As it is small, it can fit in small spaces
and so is very versatile. But it is not very
good for supporting large weights.

9. DIFFERENTIALS AND STEERINGS
Here, the first picture is a standard
non locking differential using three
12t bevel gears and the
differential casing. The second
version is the more complicated
torsen differential, which is a self
locking differential.
Here, the first picture is a rack
and pinion steering while the
other one is a very simple
steering that I have
developed myself.

10. MOTORIZATION
 .
This is the micromotor.
It is the smallest motor
and spins at a very low
speed
This is the minimotor
and is slightly bigger
than the micromotor but
much more powerful
This is the geared
motor and has an
internal gear
reduction
This is the dune buggy
motor and has a very
high RPM
This is the power
functions small motor
and is extremely
versatile and can
produce good amounts
of torque and speed.
This is the power
functions large motor
and can be mounted
very easily
This is the Power
Functions XL motor
and can deliver very
high amounts of torque
This is the Mindstorms
large motor. It is
comparable to the XL
motor but has an
additional feature of
being a servo motor
This is the Mindstorms
medium motor and is
also a servo motor. It is
comparable to the
Power functions
