DMD (Duchenne muscular dystrophy) is a genetic disorder characterized by progressive muscle weakness, leading to the eventual loss of muscle function. After losing lower extremity function, DMD patients lose the ability to use their arms. To assist individuals with DMD, an upper extremity exoskeleton is being developed to provide support. <br/>...

A novel nonlinear stiffness unit cell aided magnetic gravity compensator is proposed for the purpose of isolating low-frequency vibrations. A negative stiffness magnet setup is combined with a compliant unit cell with tailored nonlinear force-displacement characteristics. This combination offers a large range of motion featuring low stiffness, a...

Duchenne Muscular Dystrophy (DMD) patients suffer from a severe form of progressive muscular weakness. Consequently, as the disease progresses these patients become more and more dependent on assistive devices for their daily activities. For instance lifting their arms against gravity already becomes challenging. So far, a considerable amount of...

The ever increasing demand for better and cheaper electronic devices, sensors, optical components, etc. fuels innovation in nanometer precision positioning machines. However, the overall architecture of these machines has not changed much over the past years. A huge improvement in the architecture is currently impossible due to a crucial element...

The mechanism presented in this paper generates a partially negative stiffness characteristic, which is suitable for the balancing of a pendulum in a gravity field. The mechanism uses deformation in the axial direction of the base joint to store potential energy. The proposed design is located next to the base joint of the pendulum in an area...

An Integrated 6-DoF Lorentz Actuator with Gravity Compensator for Vibration / Precision Positioning has been analyzed and optimized. The gravity compensation function is realized by permanent magnets. The 6-DoF actuator is based on the utilization of the mover magnets. A demonstrator of the novel 6-DoF actuator integrated with magnetic gravity...

We present a design for a manipulator that is intrinsically mechanically safe, i.e. it can not cause pain (let alone damage) to a human being even if the control system has a failure. Based on the pressure pain thresholds for human skin, we derive a pinching safety constraint that limits the actuator torque, and an impact safety constraint that...
