Robotic gripper for calli transfer: The design and development of a robotic gripper to automate calli transfer to improve the quality and quantity of plant regeneration

During the transfer of calli in plant regeneration, the repetitive work of pick and placement of calli in new agar is still done by human operators. This process can be automated to eliminate labour-intensive work. The thesis focuses on the development of a robotic gripper to automate the transfer of calli. To be able to grip calli, first its...

An Alternative Micro LED Mass Transfer Technology: Self-Assembly

Micro LED display technology has been spotlighted as the most promising technology compared to LCD and OLED. Its excellent advantages include higher brightness, self-illumination, higher resolution, lower power consumption, faster response, higher integration, higher stability, thinner thickness, longer life, etc. In terms of the unique benefits...

The effect of pick-up point location on fibre angle devation in Non-Crimp Fabrics

For pick-and-place processes to become widely implemented in industry a consistent and acceptable product quality needs to be achieved. One important quality criterion is the fiber angle deviations in the reinforcement. Handling a reinforcement will subject it to forces due to e.g. gravity and accelerations. These forces can result in in-plane...

Straightening out the Adoption of Variable Stiffness Composite Laminates in Aerospace Industry

Significant improvements in the mechanical performance of a laminated composite structure can be achieved by spatial variation of the stiffness properties within the laminate. Such a variable stiffness (VS) laminate, typically is created by steering the fibers within the laminae, resulting in an in-plane variation of stacking sequence and thus...

A Gripper for Deformable and Delicate Objects at High Acceleration Using a Contact-Reactive Grasping Approach

Introduction: This research aims to develop a gripper that is capable of handling deformable and delicate objects at high acceleration (≥10 G) using a contact-reactive grasping approach while moving. Commercial grippers are already suitable for handling various food products at high speed and acceleration when combined with a parallel...

Design and comparison of high speed cable driven parallel pick and place robots, performing a Schönflies motion

In cable driven parallel robots (CDPRs), the end effector or moving platform is actuated by multiple cables in parallel that are wound on winches, which are located on a frame. Compared to classical parallel robots, such as the Delta robot, CDPRs have a lower inertia due to low cable masses. Therefore, they can perform high speed motions with a...

Zero-shot learning in pick-and-place tasks using neuro-symbolic concept learning

Pick and place systems that operate in a warehouse setting have been studied a lot recently due to the high economic value for e-commerce companies. In this thesis, the focus is on the perception pipeline that performs object recognition given a certain input data stream (typically RGB-D images). Impressive results regarding object recognition...

Hybrid Integration of Silicon Photonic Devices on Lithium Niobate for Optomechanical Wavelength Conversion

The rapid development of quantum information processors has accelerated the demand for technologies that enable quantum networking. One promising approach uses mechanical resonators as an intermediary between microwave and optical fields. Signals from a superconducting, topological, or spin qubit processor can then be converted coherently to...

Reasoning for Improved Capacity in Robotic Pick-and-Place Tasks

As e-commerce continues to grow, warehouses face the challenge of keeping up with product flows. Vanderlande provides a pick-and-place robot (SIR) that helps in improving capacity. However, SIR's capacity is limited by its vacuum gripper and its inability to solve failures. The aim of this thesis is to improve SIR by adding a second gripper and...

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...

Microscale surface tension and its applications

Control Strategies for Grasping and Holding Deformable Items Using a Gripper on a Robotic Arm

Because of the increasing e-commerce volume, resulting in increasing demands on the speed of delivery, logistical processes become more and more automated. Order picking is one of the last tasks that is done by humans in warehouses, because humans are flexible with respect to the large variability and changeability in items. However, it is a...

Automation Options for Custom-Made Composite Part Production

This project analyses the feasibility of the integration of an automation system for custom-made composite part production at the superyacht equipment manufacturer Rondal BV. An analysis of the current prepreg production is performed to understand the automation opportunities and production requirements. Nesting, kitting, protective film removal...

An underactuated gripper mechanism for picking objects from a tabletop

Underactuated grippers that are designed for the pick and place industry tend to pull objects into the gripper when a firm grip is required. This movement within the gripper is sometimes undesired and can damage the object. Therefore, the goal of this study is to design an underactuated gripper mechanism that is able to establish a final and...
