Kuppens, P.R. (author)
This thesis presents energy invariant mechanisms that can be scaled to micro size. They are also called statically balanced, because all static forces are balanced against each other. They enable effortless suspension of weight, and flexible devices without stiffness, seemingly defeating gravity and elasticity. In large scale applications such...

Ahmadi Dastjerdi, A. (author)
Proportional Integral Derivative (PID) controllers dominate the industry and are used in more than 90 percent of machines in this era. One of the reason for the popularity of these controllers is the existence of easy to use frequency-domain analysis tools such as loop-shaping for this type of controller. Due to the advancement of technology in...

Bos, R.A. (author)
Orthoses have evolved from simply maintaining bone fractures and correcting spinal deformities to full mechatronic systems that can read a person’s intention and translate that into a desired motion or force path. A vast variety in pathologies (e.g., stroke, muscular dystrophies), applications (e.g., daily assistance, research) and environments ...

The demand for electronic devices like telephones, tablets and computers is still growing and will grow further in the future. All these devices contain electronic components, which are placed on printed circuit boards (PCBs). The assembly of a PCB is performed by several machines in an assembly line. As the accurate placement of several...

Classical human-engineered transmission mechanisms such as linkages, gears, and couplings are well established designs which made out of multiple parts and rigid hinges. However, these mechanisms impose disadvantages such as wear, friction, low precision and reliability, need for assembly and lubrications, and difficulty for miniaturization. By...

Radaelli, G. (author)
In this dissertation a collection of concepts to synthesise nonlinear springs is presented. Such springs can be useful in various application domains where, e.g., multi-stability or static balancing is desired. These behaviors are often sought to alleviate the effort required for actuation. The explored concepts are presented by showing the...

Hoevenaars, A.G.L. (author)
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...

Dunning, A.G. (author)
The goal of this dissertation is to develop a wearable, passive, dynamic arm support that provides users with Duchenne muscular dystrophy (DMD) with support to perform activities of daily living. The arm support needs to be inconspicuous and not stigmatizing, to encourage the users to participate in social activities. Ideally, the device fits...

Lambert, P. (author)
This thesis explores the fundamentals of a new class of parallel mechanisms called parallel mechanisms with configurable platforms as well as the design and analysis of parallel robots that are based on those mechanisms. Pure parallel robots are formed by two rigid links, the base and the end-effector, connected in parallel by independent serial...

Kragten, G.A. (author)
There is an emerging need to apply adaptive robotic hands to substitute humans in dangerous, laborious, or monotonous work. The state-of-the-art robotic hands cannot fulfill this need, because they are expensive, hard to control and they consist of many vulnerable motors and sensors. It is aimed to develop simple, adaptive hands that are capable...
