LettuceThink : A open and versatile robotic platform for weeding and crop monitoring on microfarms

Precision farming and in-field phenotyping benefit from developments in robotics. However, the
technological advances are usually dedicated to large scale facilities, either monoculture farms or
research facilities. We introduce the LettuceThink robotic platform as a versatile tool to ease the
work on market farms. The design and software are modular and open source so that it can be built
with standard parts and modified to fit specific needs. We demonstrate its use with two applications:
precise mechanical weeding and 3D reconstruction of plants.
