Development of a Practical Tool in Pick-and-Place Tasks for Human Workers

Abstract

We introduce smart hand, a practical tool for human workers in pick-and-place tasks. It is developed to avoid picking up the wrong thing from one location or place the things in an unexpected location. Smart hand features sensors (e.g., imaging sensors, motion sensors) to sense the world and offers suggestions or aid based on the sensed results when a human worker is performing a pick-and-place task. A smart hand prototype is made in the study. In our design, the smart hand has an RGB-D sensor and an inertial measurement unit (IMU). RGB-D sensor is used to do object detection and distance/position estimation while IMU is used to track the motion of the smart hand. An experiment is conducted to compare the two working conditions that a subject performs the pick-and-place tasks with or without the smart hand. The experiment results proved that the smart hand can avoid human errors in pick-and-place tasks.

Implementation analysis of vacuum area gripping system in pick and place machinery in wooden door company

“…The gantry handle lowers to the door, suctions and moves the wooden door to the desired location, and finally the handle lowers to the lowest point and places the door. The wooden door is transported to the roller table beneath the gantry type loading and unloading machine [9] [10]. The manufacturers' specifications for pick-and-place machines can be used to calculate the necessary requirements, and estimates concerning the need for vacuum devices and suction motors can be used to gather data.…”
