Tree Measurer - Construct

The tree measurer's design is apparently ideal for measuring objects that has the length/width of the space between the mobile caliper and immobile caliper. The robot's gear configuration (power from one motor) is significant to the movement of the caliper which allows it to measure an object; additonally, there is even a handle which makes it very easy to handle.

Overall the design is quite modular, however, the limit as to the size of the calipers* is a disadvantage.
