Assembly 5 - Wheels, Tyres and Rear Skid
The Microbot is driven by two wheels at the front and uses a skid to
support itself at the rear. Each wheel has a tyre which must be fitted and
the skid assembly consists of four parts; a bric, a 14mm support post, a
bolt and the plastic skid itself.
Gently stretch the tyres over the wheels and once in place ensure the tyre
is evenly fitted, check there are no bumps and that each tyre’s width is
consistent all the way around the wheel
Fit the wheel and tyre
assemblies to each of the
motor housing axles.
These are a push fit. Either
wheel can be fitted to
either motor.
To assemble the rear skid, the 14mm support post should be pressed into
the centre hole of its mounting bric as far as it will go.
The skid cover should then be slipped over the 14mm support post.
Align the skid assembly with the centre connection point at the back of
the motherboard. The two posts of the bric will fit into the two holes of
the centre connection point. When correctly oriented the connecting bric
will fit flush with the motherboard. If incorrectly fitted the connecting
bric will be angled to the motherboard; in this case remove the
connecting bric, rotate it through 180 degrees and refit.
Once the connecting bric
has been correctly aligned
with the centre connection
point at the back of the
motherboard it should be
bolted it into place with a
single bolt.
If desired you may also
choose to connect the
servo module here at the
same time, as this helps
strengthen the connection.
This is how your Microbot should now look.
