This paper describes four-wheeled robotic chassis of the autonomous mobile robot Bender II utilizing Ackermann steering and independent rear drive units. The robot is designed for the use in outdoor environment. Independent rear drive gives better traction in uneven terrain with the cost of doubling the motion hardware (motors, gears and controllers). Hardware and software implementation details as well as practical experiences of this approach deployment are presented.
This paper presents a novel approach to the design of a motorized rehabilitation device -active elbow orthosis (AEO) -inspired by the principles of robotic exoskeletons. The device is currently designed for the elbow joint, but can be easily modified for other joints as well. AEO determines the motion activity of the patient using a strain gauge and utilizes this measurement to control the actuator that drives the forearm part of the orthosis. Patient activity level is related to a free arm measurement obtained via a calibration procedure prior to the exercise. A high-level control module offers several types of exercises mimicking the physiotherapist. The device was successfully verified by tests on a number of patients, resulting in extended range of elbow-joint motion.
For more than three years we have been researching the possibilities of robot programming teaching at elementary schools. The aim is to increase an interest in technical subjects of study at secondary schools and universities with a technical orientation. Research has revealed many interesting facts, on the basis of which the methodology and teaching was proposed and production of robotic system kits was developed and launched. The system allows continuous education from primary school to university including production of prototypes of automation and robotic systems. In fact, construction suitability and quality has already been tested in practice. It turns out that education has a significant positive influence on both the natural and mutual authority of student -student and student -teacher and pupil discipline, diligence, consistency and the ability to solve problems. Further, it also influences the area of occupational safety and active creative use of IT technologies..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
