A study on micro-gripping technologies

Risicoscan Rondweg Druten-Beneden Leeuwen (N322)

De afdeling Wegenbouw van de provincie Gelderland wil het risicobewustzijn in haar afdeling verankeren en verbreden. Om dit te bewerkstelligen wil de afdeling een methodiek voor risicomanagement implementeren in de bestaande werkprocessen met behulp van ondersteunende tools. Voorafgaand aan dit implementatietraject wil de afdeling voor het einde...

Vacuum grasping as a manipulation technique for minimally invasive surgery

Background- Laparoscopic surgery requires specially designed instruments. Bowel tissue damage is considered one of the most serious forms of lesion, specifically perforation of the bowel. Methods - An experimental setting was used to manipulate healthy pig bowel tissue via two vacuum instruments. During the experiments, two simple manipulations...

Learning to use a body-powered prosthesis: changes in functionality and kinematics

Background: Little is known about action-perception learning processes underlying prosthetic skills in body-powered prosthesis users. Body-powered prostheses are controlled through a harness connected by a cable that might provide for limited proprioceptive feedback. This study aims to test transfer of training basic tasks to functional tasks...

Parallel manipulators with two end-effectors: Getting a grip on Jacobian-based stiffness analysis

Robots that are developed for applications which require a high stiffness-over-inertia ratio, such as pick-and-place robots, machining robots, or haptic devices, are often based on parallel manipulators. Parallel manipulators connect an end-effector to an inertial base using multiple serial kinematic chains. This architecture enables the design...

Strategies for swift automated pick-and-place operations of multiple large-sized layers of reinforcement - a critical review

For the application of composite materials to become more widespread and replace traditional materials their manufacturing processes and final products will need to be competitive and be e.g. lighter, stronger or stiffer and quicker, easier or more cost-efficient to produce than traditional materials. The state of the art for pick-and-place...

Design of a bio-inspired soft robot for break bulk manipulation in transport engineering

This research explores the possibility of upscaling bio-inspired designed soft robots in transport engineering application with the focus on grabbing and manipulating break bulk such as windmill blades or rolls of steel. Upscaling current state soft robotic systems includes challenges regarding the structural strength of the robot. Also...
