Opis:
While working on a system for verticalization and aiding the motion of the disabled, the problem emerged related to evaluation of the effect of individual traits of the users of the system on the obtained characteristics of the actuators. Studies that have been carried out so far were limited strictly to a case of an ordinary male. The traits of the user will significantly influence operation of the robot, therefore it was decided to carry out studies within a wide range of variability of the basic anthropometric traits. The paper presents a way of determining parameters, which were being changed during the studies, as well as a general structure of the simulation model. Then, a method of computing the energy consumed by the actuators is described, and results of the realized simulation experiments are presented.
Podczas pracy nad systemem pionizacji i wspomagania ruchu osób niepełnosprawnych, pojawił się problem związany z oceną wpływu poszczególnych cech użytkowników systemu na uzyskane charakterystyki siłowników. Badania, które zostały przeprowadzone do tej pory były ściśle ograniczone do przypadku zwykłego mężczyzny. Cechy użytkownika znacząco wpływają na działania robota, dlatego zdecydowano się przeprowadzić badania w szerokim przedziale zmienności podstawowych cech antropometrycznych. Przedstawiono sposób określania parametrów, które były zmieniane w trakcie badań, a także ogólną strukturę modelu symulacyjnego. Następnie opisano metodę obliczania energii zużywanej przez siłowniki i przedstawiono wyniki zrealizowanych eksperymentów symulacji.

Opis:
The paper presents studies pertaining to the quality of embossed characters of the Braille alphabet used, among other applications, for tagging drug labels. The following parameters of embossed inscriptions were measured: height, diameter of the dots and surface roughness (18 samples with various combinations of their values). 48 blind individuals assessed the quality of the printed text. Statistical analysis proved that a text with dots having height of 0.9 millimeter, diameter of 1.6 millimeters and roughness Ra of about 1 micrometer to be the best. The samples had been made using two different methods of rapid prototyping: PolyJet and SLS. 3D printing is increasingly popular and the studies proved the usefulness of these methods for labeling with embossed inscriptions, due to the repeatability, durability and quality they ensure. The assessing group of blind individuals was comprised of 24 persons 14–17 years old and other 24 persons aged over 60 who were not proficient in reading Braille alphabet, This allows to conclude that a text featuring the above values of the parameters will be easy to read for the majority of blind persons.

Opis:
There has been designed a device for verticalization and aiding the gait of individuals suffering from paresis of the lower limbs. It can be counted in the category of so-called “wearable robots”, whose task is to replace or aid human limbs. Dependently on the function realized, these robots are classified into one of the following three groups: a) exoskeletons - strengthening the force of human muscles beyond their natural abilities, b) orthotic robots - restoring lost or weakened functions of human limbs, c) prosthetic robots - replacing an amputated limb. A significant feature of the device that has been designed is the fact that it has not to replace human limbs, but only restore them to their lost motor capabilities. Thus, according to the presented classification, it is an orthotic robot. Unlike in the case of the existing systems for verticalization, the gait is to be realized in a way that is automatic to the highest possible extent, keeping the user involved as little as possible, and the device is to imitate the natural movements of man with the highest fidelity. Within the works on the system for verticalization and aiding the motion, a simulation model of the device was created. It includes a structure of the robot, a model of the actuators and a model of the human body that constitutes the load for the driving units. Then, simulation studies were carried out, including evaluation of the power demand of the device as well as the influence of the gait rate and of the length of the steps on the operation of the system.

Opis:
Mechatronics is nowadays a dominating concept in design of various kinds of systems and technical devices. High speeds of data processing by control units of mechatronic systems, as well as high dynamics of their actuators allow the systems to be applied in wider fields. This refers to the medicine as well, especially while making attempts to replace lost human motor abilities by means of robots aiding the man. These devices can be divided into three groups: exoskeletons designed to strengthen the natural force of human muscles, orthotic robots that restore lost or weakened functions of human limbs, and prosthetic robots replacing an amputated limb. The first and the third group are known quite well, whereas the orthotic robots are at an initial phase of their development. The authors have worked on a device for aiding the motion of disabled people suffering from paresis of the lower limbs. The paper presents a concept and a structure of the system that has been created, comparing it with similar devices that have already existed. There are indicated some connections and areas where the subunits merge, as well as the rules of their working with the user.
