‘search and rescue’ double arm grabber

Through a rear vertical gear clutch lever a single cream gear on top controls through the turntable either the opening or closing of one of the grabbers, or the lifting up and down of the grabber arm.

The black knob controls the horizontal movement of one of the arms through 90 degrees.

The above is mirrored for the other arm and grabber to create twice the play on the same area as a normal tracked base.

Designed to be as compact as possible for ease of transportation and to keep the brick count at around 700 using two 42006 Lego sets and some spares.

Each half can be played with separately, so they can independently search and rescue, or split to go around obstacles and re-join afterwards!

Expandable in-between each half with two motors, one to control each set of tracks and above 3 functions using a 2nd clutch lever.
