1.Introduction
Precision Agriculture(PA) is now a day’s buzzword
used for the implementation of Mechatronics,
Robotics, and Artificial Intelligence in various
agricultural and allied tasks [1]. These robots are
highly complex with different subsystems, which need
to be integrated. This integration is possible using the
Design Thinking approach. Mechatronics design of
such a system mainly includes a synergetic
amalgamation of different disciplines of engineering
like Mechanical, Electronics, Computer, IT, and
intelligent control systems.

Fruit harvesting is a very labor-intensive task that
needs to be automated. Mechatronics modules for the
various agricultural and allied tasks along with
different types of fruits and vegetable harvesting
robots working in the different agricultural
environments have been developed in the last few
decades [2–4]. Each year half the fruits, vegetables of
the world produce are wasted with the reported loss in
the range of 4.58% to 15.88%. Major quality
deterioration and loss occurred during the manual
harvesting process of horticulture and greenhouse
produce which is also a labor-intensive task. The
conventional harvesting process in viticulture also
results in damaging the thin waxy layer from the major
export quality fruits like Table grapes, reducing the
shelf life of the grapes.

Abstract
Motivation for current work is to reduce the harvesting cost and increase the shelf life of the post-harvested yield of grapes
and greenhouse produce using harvesting robots. A novel end-effector design comprising of cutter integrated with a gripper
is developed, tested, and validated for harvesting different types of Greenhouse produce. For evaluating the efficacy of the
novel end-effector, experiments are carried out on various vegetables and fruits like Table Grapes, Sweet Bell Pepper, Bitter
Melon, Long Hot Chili Pepper, Eggplant, and Okra with average harvesting time of 28,19,17,20,17 and 18 seconds
respectively. The designed novel end-effector viz. gripper cum cutter is compact in size and lightweight. It is attached to a
custom-built pneumatically operated robotic arm, mounted on a multi-purpose agricultural vehicle. Once the fruit is
detected through image sensing, a mechatronic module activates the gripper first to firmly grasp the peduncle of fruit, and
the cutter cuts it, without any physical contact with fruit, resulting in the increased shelf life of fruit. The harvesting module
is capable of harvesting various fruits and vegetables with an effective field capacity of 4.625 ha/hr with an effective
operating time of 9.25 hrs in a 10 hours of a day with a field efficiency of 92.5%.
