Mechanical figures that mimic human motions continue to entertain us and capture our imagination. Creating such automata requires expertise in motion planning, knowledge of mechanism design, and familiarity with fabrication constraints. Thus, automaton des ...
Disclosed are methods and devices for distributed sensing of a measurable parameter employing stimulated Brillouin scattering in an optical fiber. A frequency-modulated or phase-modulated light wave is transmitted into the optical fiber. A scattered light ...
We demonstrate the demolding of topologically complex three-dimensional elastomeric microstructures from a femtosecond laser micromachined glass substrate. Demolding success rates of > 90% are achieved, which are qualitatively supported by a simple mechani ...
The basic idea of the project (run in collaboration with a Swiss company) is to design a flexible winding, which will 'replace' the classical slotless BLDC motor winding. The new winding should be thermally and mechanically improved compared to the classic ...
This paper presents the results of an extensive experimental campaign on 16 flat-slab specimens with and without punching shear reinforcement. The tests aimed to investigate the influence of a set of mechanical and geometrical parameters on the punching sh ...
Pressure tunnels are in operation subjected to internal water pressure. When the hoop tensile stress acting at the lining intrados exceeds the tensile strength of concrete, longitudinal cracks occur in the concrete lining. As a consequence of crack opening ...
Increasing situational awareness at human-machine interface level is a key success factor for high efficiency therapies and surgical procedures. On a technical level, cost-effective, reliable sensor integration becomes the most critical element where multi ...
Throwing is a complex and highly dynamic task. Humans usually exploit passive dynamics of their limbs to optimize their movement and muscle activation. In order to approach human throwing, we developed a double pendulum robotic platform. To introduce passi ...
Fluid flow in biological tissues is important in both mechanical and biological contexts. Given the hierarchical nature of tissues, there are varying length scales at which time-dependent mechanical behavior due to fluid flow may be exhibited. Here, spheri ...
In this paper we present the key phases to design and calibrate ultra-high-precision industrial robots (i.e. submicrometric precision robots). The first part of our study will cover the robot design aspects, from the choice of the kinematics with the help ...
