Kurzfassung: Zur mechanischen Unterstützung des menschlichen Be-wegungsapparates schreitet die Entwicklung von Exoskeletten voran. Be-stehenden Systemen fehlt jedoch die Marktdurchdringung, da diese meist Individuallösungen darstellen. Mit diesem Beitrag stellen wir ein Konzept für ein Exoskelett der aktiven Unterstützung des Hand-Arm-Schulter-Syst...

Sowohl in der klinischen Diagnostik als auch bei der Untersuchung biomechanischer Fragestellungen in der Medizin, der Sportwissenschaft und weiteren Anwendungsgebieten wie der Medizintechnik werden verschiedene Verfahren der Bewegungsanalyse genutzt. Dabei sind die etablierten Verfahren häufig sowohl teuer als auch aufwendig in der Anwendung. Zu de...

This chapter considers locomotion in living machines, focusing particularly on mammals and on the possibility of designing mammal-like quadrupedal robots. Locomotion is the movement of an organism or a machine from one place to the other, covering a defined minimal distance. In organisms, locomotion usually is driven by a central element and/or app...

In the follicle sinus complex of sinus hairs in mammals two blood vessels seem to have a prominent function. Up to date their biological role is unknown. Hypotheses suggest that they are used as a hydraulic bearing for the hair shaft which is able to change the stiffness and compliance of the fixation depending on the application. Thereby different...

Die Bewegungsanalyse an Menschen basiert wesentlich auf vier Messverfahren: • Kinemetrie: Messung von kinematischen Daten = Bewegungsbeschreibung, • Anthropometrie: Vermessung der geometrischen und mechanischen Eigenschaften des Körpers, • Dynamometrie: Messung der auf den Körper von außen wirkenden Kräfte, zumeist Bodenreaktionskräfte und • Elektr...

In the follicle-sinus-complex of sinus hairs in mammals, two blood sinus seem to have a prominent function. Up to date, their biological role is unknown. Hypotheses suggest that they are used as a hydraulic bearing for the hair shaft which is able to change the stiffness and compliance of the support depending on the desired application. Thereby, d...

While the facial (mystacial) sinus hairs are intensively studied regarding their structure, follicle anatomy and biological role in various mammals, less is known about the tactile hairs found on the palmar side of the rat's forelimbs near the wrist. These carpal sinus hairs are assumed to play an important role during locomotion in dark or narrow...

Facial (mystacial) vibrissae, a kind of sinus hairs within the group of tactile hairs, have been intensively studied for muscle activities, neurological patterns, anatomy details and their biological role in different species. The skill to move in a more or less regular pattern (whisking) is known from various species, like rats. In addition to the...

During the flow of evolution, animals have developed specific sensory systems for the interaction with their environment. One example are tactile hairs – so called sinus hairs or vibrissae – on the body surfaces of mammals. These sinus hairs provide inspiration for technical development, since the variability of the biological sensors is due to mec...

Sinus hairs are tactile hairs of mammals, commonly also known as vibrissae or whiskers. The term “whisker” contemplates to the mystacial sinus hairs (mSH) in specific, which are situated around the snout of the animal. These mystacial sinus hairs can be moved actively to support and control sensing [1, 29]. The cyclic motion (whisking) of the mysta...

Excitation of sensors triggered by carpal vibrissae has an influence on the kinematics of legs during locomotion of rats. Via motion studies, anatomic and mechanical characterization of vibrissae – especially in the contact period with the substrate – we try to gain a better understanding of the adaptability of those special sensory organs. This kn...

This extended abstract introduces the biologically inspired swimming robot URMELE light. The robot embodies the strategy of massive under-actuation. Propulsion is generated using a central module with one single actuator and coupled passive, compliant tail modules. Therewith this robot differs from other modular swimming robots like e.g. AmphiBot [...

The idea of biomechatronics is based on the observation, that for mechatronic as well as for living systems a high degree of functional integration is characteristic. This allows biomimetic approaches without logical constraints. On the other hand, modularization is a major strength of mechatronics, while in life sciences “module” is a functional a...

Vibrissae or tactile hairs, commonly known as whiskers, are the mechanical gates of special mechano-sensitive organs. In terrestrial mammals, they carry various functions, especially object determination and texture discrimination. We hypothesise that the characteristic morphology and structure of whiskers is a primary morphological condition for t...

We report about the investigation of the amoeboid locomotion at Amoeba proteus. Based on the detailed experimental study of the internal cytoplasm flow and the variation of the contour of the amoeba with optical flow measurement techniques like particle image velocimetry (PIV) we found characteristic velocity fields and motions of the center of mas...

We report about micro PIV measurements of the internal flow in the protoplasm of an amoeba. The velocity data shall give information about the mechanism of the change of amoeba's contour during its locomotion in water. The experimental data is used for an analytical modeling of the locomotion mechanism with the help of a variable contour and finall...

Discussions on transitions from quadrupedalism to bipedalism beneath ecological aspects have to take into account the mechanical interactions of the animals with the substrate. The observable shift from higher forelimb loads in non-primates to higher hindlimb loads in primates points onto the need of measuring and modeling the moment transfer betwe...

At Technical University of Ilmenau a Peristaltically Actuated Device for Minimal Invasive Surgery (PADeMIS) is being developed. PADeMIS will be produced from silicone rubber and its design is being optimized by Finite Element Analysis (FEA). Thus, a constitutive law of silicone rubber is required. When an element of PADeMIS is hydraulically actuate...

The kinematics of scapula and shoulder joint movements were analyzed in three species of arboreal quadrupedal primates using cineradiography. Our findings indicate that scapular movement is highly important for forelimb movement in primates with this ancestral mode of locomotion. Retroversion of the scapula (syn. caudal rotation or extension) durin...

The postural and locomotor activity and its relation to substrates was observed in 3 Saguinus oedipus, and 3 Saimiri sciureus for comparison, during a period of 10 h for each individual. The animals moved freely in cages of 3.40 m x 3.40 m x 2.40 m (height) on rather diverse substrates. Observations were made according to the focal-animal-method, w...
