Robot 10 • RIS Turtle

Turtle Step 8

Here you add another ratchet to the gear that drives
the belt, which in turn will drive the gear shifter.
The purpose of this ratchet is the same
as the one for the penholder. It only
allows the gear shifter to
rotate in one direction.

Turtle Step 9
Flip the model over and
add these pieces to the
bottom of the body
platform. The pins here
are used for cross bracing.
