The mech |
The driving mechanism assembled. The mechanism is attached |
209 |
|
to the LEGO framework by the long axle; the driving tyre |
210 |
|
is on one end of the 1x5 liftarms and |
211 |
|
a towball for attaching a rubber band |
212 |
|
at the other. |
213 |
|
The rubber band is used to pull the towball upwards, |
214 |
|
which in turn presses the tyre downwards. |
215 |
|
The force is easily adjustable by adjusting the other |
216 |
|
end of the rubber band. |
