The paper presents an observation and evaluation of the recovery process. Seven weeks after the fracture of the fibula and six weeks after surgery the measurement of the gait of the subject has been started. Inertial measurement units applied above both ankles are used to acquire kinematical data and three surface EMG at each leg to get information about the activity of three muscles. The intensity of the weekly tests has been increased in dependence on the healing progress. Both scenarios-walking on the floor and on the treadmill-were included in the experiments to obtain comparable data sets. Beside of the investigation of the healing process the paper is focused on symmetry/asymmetry properties of the gait. The results indicate that asymmetry is not only an essential property of pathologic gait but it is present in normal gait too, especially if short distances are evaluated. They may be caused by the influence of a dominant/injured leg, of the first/last steps, the natural variance of the gait or the daily fitness of the subject. Asymmetry is obviously in the contribution of both legs to a stride (step length, strike and lift angle, stand and swing phase).
Towards Practice-oriented Higher Education for Sustainable Rural Development in Western Kenya
(2021)
The workshop proceedings contain the written versions of the presentations of the Kenyan participants of the final workshop of the DAAD-funded cooperation project "Practice-oriented Higher Education in Western Kenya" (ProUniEdu-WeK) in August 2021 at the Brandenburg University of Applied Sciences (THB).
The contributions give an impression of what has been achieved in the last years on the way to practice-oriented higher education in the participating departments of the Masinde Muliro University of Science and Technology (MMUST) in cooperation with its partners from the THB and what is planned to be done in the years to come.

An intelligent robot platform for autonomous systems with vision capabilities has been developed by the University of Applied Sciences Brandenburg in cooperation with SME's. The system is suitable as a research and education platform for universities, a basis for industrial applications and for private developers of robots. This paper presents an architecture overview and application details of the RCUBE system. RCUBE is available in 2 modular versions: (1) a cost-effective platform for reactive robots and private developers (2) a performant platform for intelligent robots with image processing capabilities suitable for research, development and education in the field of service robotics. The system consists of 3 ready-to-program hardware modules with a basic software layer. They can be combined in different configurations. The modularity provides the flexibility to configure an RCUBE system for different application areas, but also single modules can be used in applications such as autonomous intelligent cameras or planning robots (e.g. lawnmower, vacuum cleaner). A key feature is the capability to autonomous image processing combined with sensors and actors, small size and low power consumption. RCUBE opens the way to small independent seeing robots.
Since 1995 mobile robot systems have been
investigated and included in the education process.
Using commercial and/or open source platforms like
LEGO-techniques with the 6.270-Board [5], the
EyeBot controller [3] or the PIONEER robots [10]
various aspects of mobility, sensing, control and
navigation were taken into account. The limited
abilities of all these platforms in computing power or
image processing required the development of a new
hardware platform called RCUBE [2], [11] combining
the features of a typical actuator-sensor-input-outputboard
with computing power and image recognition
capabilities. The system is suitable as a compact
platform for universities, small enterprises and private
developers.
Since 1995 autonomous, intelligent or mobile robot systems have been investigated and included in the education process. Using commercial and/or open source platforms like LEGO-techniques with the 6.270-Board (Flynn, A.M. and Jones, J.L., 1996), the EyeBot controller (Braunl, Th., 2002) or the PIONEER robots various aspects like mobility, controllability, sensor fusion, line or object recognition, navigation and control strategies were taken into account. The limited abilities of all these systems in computing power or image processing required the development of a new hardware platform called RCUBE (Boersch, I., et al., 2003) combining the features of a typical actuator-sensor-input-output-board with computing power and image recognition capabilities. The system would be suitable as a compact platform for universities, small enterprises and private developers.
