The current approach to reducing impact forces during component placement in micro-assembly is to couple the gripper with 5 Degrees Of Freedom (DOF) to the drive unit of the placement device, wherein the mass of the gripper has been reduced maximally. At the end of the placement motion the drive unit will move relatively to the gripper, as linear as possible given the limitations of the constru...

Rapid and versatile object manipulation in air is an open challenge. An energy-efficient adaptive soft gripper combined with agile aerial vehicle could revolutionize robotic areas such as warehousing. This paper presents a bio-inspired powered by hydraulically amplified electrostatic actuators mounted to quadcopter that can interact safely naturally its environment. Our gripping concept motivat...

This paper presents a comparative study of the use different fingertips in robotic gripper jaws with respect to measuring pulling force selected shaped objects from their grasp. The authors built dedicated test stand and provided methodology evaluate it. authors’ innovative approach was design accessory-controlled for base Robotiq 2F-140 gripper. For study, rigid structures—flexible soft cushio...

This work proposes a novel generative design tool for passive grippers -- robot end effectors that have no additional actuation and instead leverage the existing degrees of freedom in robotic arm to perform grasping tasks. Passive are used because they offer interesting trade-offs between cost capabilities. However, designs limited types shapes can be grasped. use rapid-manufacturing optimizati...

results twelve original studies fulfilled the inclusion criteria. the current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. conclusions there are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and ou...

Grasping and manipulating uncooperative objects in space is an emerging challenge for robotic systems. Many traditional robotic grasping techniques used on Earth are infeasible in space. Vacuum grippers require an atmosphere, sticky attachments fail in the harsh environment of space, and handlike opposed grippers are not suited for large, smooth space debris. We present a robotic gripper that c...

The robotic arms of the human arm type, so-called collaborative robots, have been improved, optimized, and diversified greatly in recent years. However, most them are still equipped with mechanical grippers plier-like jaws. Equipping these anthropomorphic is currently hampered by variants on market that far too complex at inaccessible prices to be used a large scale. As an alternative familiar ...

It is often suggested that hand prostheses and robot grippers must possess a kinematic structure that is similar to those of the natural human hand [1-4]. Such structure allows better adaptation of the gripper to the size and the shape of the grasped object and better cosmetic effect. Anthropomorphic hands with a large number of joints are highly dexterous, but their independent joint control r...

Assistive robotic arms hold great potential to assist individuals with motor impairments in performing pick-andplace tasks, object retrieval tasks, or even assist with personal hygiene and feeding. There are about 150,000 people in the United States who could benefit from using such assistive technology [4]. However, robotic arms typically have a much higher number of controllable degrees of fr...
