Abstract:In this paper, we present a recent survey on robotic grippers. In many cases, modern grippers outperform their older counterparts which are now stronger, more repeatable, and faster. Technological advancements have also attributed to the development of gripping various objects. This includes soft fabrics, microelectromechanical systems, and synthetic sheets. In addition, newer materials are being used to improve functionality of grippers, which include piezoelectric, shape memory alloys, smart fluids, carbon fiber, and many more. This paper covers the very first robotic gripper to the newest developments in grasping methods. Unlike other survey papers, we focus on the applications of robotic grippers in industrial, medical, for fragile objects and soft fabrics grippers. We report on new advancements on grasping mechanisms and discuss their behavior for different purposes. Finally, we present the future trends of grippers in terms of flexibility and performance and their vital applications in emerging areas of robotic surgery, industrial assembly, space exploration, and micromanipulation. These advancements will provide a future outlook on the new trends in robotic grippers.

“…The sharp distinction of colors between the mature strawberry fruits and other parts of the plant can facilitate the detection process. Most of the strawberry harvesting robots have used digital RGB cameras with CCD or CMOS imaging sensors to seek red color in successive image frames on-the-go [Arima et al, 2001;Tarrio et al, 2006;Guo et al, 2008;Hayashi et al, 2009Hayashi et al, , 2010aHayashi et al, , 2010bHayashi et al, , 2012Hayashi et al, , 2014aHayashi et al, , 2014b (mobile harvesting robot); Rajendra et al, 2009Rajendra et al, , 2011Takeshita et al, 2010;Feng et al, 2012aFeng et al, , 2012bCui et al, 2013]. CCD digital cameras provide high quality imagery, but they are expensive.…”

“…Also, a harvesting robot with a 7-DOF articulated manipulator arm together with a sliding end-effector was developed in order to grab and pull strawberries (Takeshita et al, 2010). In a strawberry harvesting study, the robot's cylindrical manipulator was designed with two translational DOF and one rotational DOF (Hayashi et al, 2009(Hayashi et al, , 2010a(Hayashi et al, , 2010b. It translated along both upward-downward and forward-backward directions.…”

Review of Robotic Technology for Strawberry Production

With an increasing world population in need of food and a limited amount of land for cultivation, higher efficiency in agricultural production, especially fruits and vegetables, is increasingly required. The success of agricultural production in the marketplace depends on its quality and cost. The cost of labor for crop production, harvesting, and postharvesting operations is a major portion of the overall production cost, especially for specialty crops such as strawberry. As a result, a multitude of automation technologies involving semi-autonomous and autonomous robots have been utilized, with an aim of minimizing labor costs and operation time to achieve a considerable improvement in farming efficiency and economic performance. Research and technologies for weed control, harvesting, hauling, sorting, grading, and/or packing have been generally reviewed for fruits and vegetables, yet no review has been conducted thus far specifically for robotic technology being used in strawberry production. In this article, studies on strawberry robotics and their associated automation technologies are reviewed in terms of mechanical subsystems (e.g., traveling unit, handling unit, storage unit) and electronic subsystems (e.g., sensors, computer, communication, and control). Additionally, robotic technologies being used in different stages in strawberry production operations are reviewed. The robot designs for strawberry management are also categorized in terms of purpose and environment.
