A new algorithm for pick‐and‐place operation

Abstract

Purpose

This paper aims to represent a novel framework for optimization of robotic handling from disarray to structure where the products are randomly distributed on a surface, the initial location of the products are known (with the aid of image processing, laser position sensors, etc.) and there is a set of final positions for the products.

Design/methodology/approach

Pick‐and‐place is one of the main solutions especially for the food products where the products are prone to damage, have adhesive surfaces and the grippers can be complicated. The aim of this paper is to maximize the utilization of the pick‐and‐place robotic system. In order to do so the handling process is modelled mathematically and the pick‐and‐place problem is formulated based on assignment problem where Hungarian algorithm is utilized to minimize the total distance travelled by the robot. Furthermore, a simulation program is developed to demonstrate the possible improvements of the algorithm in comparison with the existing algorithms.

Findings

Utilizing the proposed algorithm can significantly increase the utilization of robots in the pick‐and‐place operation.

Originality/value

The new optimization algorithm can be applied to any industry with pick‐and‐place where time efficiency and maximum utilization matters.
